Circular_text TITLE: GCN CIRCULAR NUMBER: 14204 SUBJECT: GRB 130215A: Swift detection of a burst DATE: 13/02/15 01:50:26 GMT FROM: Scott Barthelmy at NASA/GSFC V. D'Elia (ASDC), S. D. Barthelmy (GSFC), N. Gehrels (NASA/GSFC), J. A. Kennea (PSU), A. Y. Lien (NASA/GSFC/ORAU), C. B. Markwardt (NASA/GSFC) and B. Sbarufatti (INAF-OAB/PSU) report on behalf of the Swift Team: At 01:31:30 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 130215A (trigger=548760). Swift did not slew because of Moon constraint. The BAT on-board calculated location is RA, Dec 43.479, +13.371 which is RA(J2000) = 02h 53m 55s Dec(J2000) = +13d 22' 14" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows a single peak with a duration of about 40 sec. The peak count rate was ~1300 counts/sec (15-350 keV), at ~1 sec after the trigger. Due to a Moon observing constraint, Swift cannot slew to the BAT position until 14:00 UT on 2013 February 18. There will thus be no XRT or UVOT data for this trigger before this time. Burst Advocate for this burst is V. D'Elia (delia AT asdc.asi.it). Please contact the BA by email if you require additional information regarding Swift followup of this burst. In extremely urgent cases, after trying the Burst Advocate, you can contact the Swift PI by phone (see Swift TOO web site for information: http://www.swift.psu.edu/too.html.)

Reichart, J. Moore, H. N. Frank, T. Cromartie, R. Egger, A. Foster, N. Frank, M. Nysewander, A. Oza, E. Speckhard, A.Trotter, and J. A. Crain report: Skynet began observing the field of GRB130215A (Swift trigger 548760, GCN 14204) in BVRI beginning ~12 minutes after the burst using four of the PROMPT telescopes located at CTIO in Chile, and the DSO-14 telescope and Morehead telescope in North Carolina, USA. A bright, fading source is detected at the position reported by the ROTSE group (GCN 14205.) Calibrating to several nearby USNO B1.0/NOMAD stars, we find the following initial magnitudes: Filt Time Mag B 15.4m 15.4 V 15.4m 14.5 R 13.0m 13.8 I 15.5 13.3 The object has set in Chile, but further observations from the Northern hemisphere telescopes are ongoing.

Circular_text TITLE: GCN CIRCULAR NUMBER: 14207 SUBJECT: GRB 130215A: Redshift estimate DATE: 13/02/15 02:57:36 GMT FROM: Antonino Cucchiara at UCSC/UCO Lick A. Cucchiara (UCSC/UCO Lick), M. Fumagalli (Carnegie Observatory/ Princeton University), report on behalf of a larger collaboration reports: On February 15.1 UT (~50 minutes after the BAT trigger) we observed the field of GRB 130215A (D'Elia et al., GCN 14204, Zheng et al GCN 14205) using the KAST Spectrograph on the Lick Shane 3-m telescope. The optical candidate is clearly detected. We obtained a 2x600s spectrum, covering the wavelength range 3500-8000A The spectrum reveals strong absorption lines of MgII2796, MgII2803, MgI2853, FeII2586, FeII2600, and Ca H&K. A provisional reduction gives a redshift of z=0.597, which we believe is most likely the redshift of this burst. We thank the Lick Observatory staff for their prompt support.

Circular_text TITLE: GCN CIRCULAR NUMBER: 14208 SUBJECT: GRB 130215A: ROTSE-III data analysis DATE: 13/02/15 04:07:03 GMT FROM: Weikang Zheng at U.of Michigan W. Zheng (UC Berkeley), H. Flewelling (IfA/Hawaii), T. Guver (Sabanci U), F. Yuan (Australian National University), report on behalf of the ROTSE collaboration: Further analysis of ROTSE-IIIb data revealed that the OT of GRB 130215A (Swift trigger 548760; D'Elia et al., GCN 14204; Zheng et al GCN 14205; LaCluyze et al. 14206) peaked around 750s after the burst, followed with a single power-law decay with index alpha = -1.24 up to ~4ks after the burst. Observation is on going. Interestingly the GRB is also triggered by Fermi-GBM (trigger 382584689). The GBM trigger arrived ~600s earlier than Swift-BAT trigger and ROTSE-IIIb responded to GBM trigger at first. A 4x4 tiling follow-up mode was performed before BAT-trigger interrupted it and a total of 22 images were obtained to GBM trigger. Unfortunately, our effort of the tiling follow-up still didn't cover the OT location in these images since the GBM trigger is about 3.78 degree away, just a bit away from one of the corner.

Cenko (UC Berkeley) reports on behalf of a larger collaboration: We imaged the location of the Swift GRB130215A (D'Elia et al., GCN 14204) with the robotic Palomar 60 inch telescope. Images were obtained in the SDSS r', i', and z' filters beginning at 02:29 UT on 2013 Feb 15 (~ 1 hr after the Swift trigger). We detect a bright point source at the location of the optical counterpart (Zheng et al., GCN 14205) in all filters. Using several nearby point sources from the USNO-B1 for reference, we measure a magnitude of R = 15.9 at this time. Observations are ongoing.

Keating (UC Berkeley) report on behalf of a larger collaboration: We began observations of the position of GRB 130215A (D'Elia et al., GCN 14204) with the Combined Array for Research in Millimeter Astronomy at a frequency of 93 GHz (3mm) starting at 03:28 UT, 1.95 hours after the burst. Observations continued until 05:03 UT (midpoint t=2.73 hours.) A provisional reduction of the data shows a strong detection of a source consistent with the location of the optical afterglow (Zheng et al., GCN 14205). We estimate a preliminary flux at this time of 2.99 +/- 0.39 mJy. Follow-up observations are planned. We thank the CARMA staff for executing these rapid observations.

Fugazza, V. d'Elia, on behalf of the REM team report: We imaged the field of GRB130215A (D'Elia et al., GCN 14204) with the REM NIR camera with the J, Hand Ks filters. Observations started at 2013/02/15 01:43:21, i.e. about 12 min after the prompt event. The optical counterpart detected by ROTSE-IIIb (Zheng et al., GCN 14205) was well detected and still fairly bright at H=11.6+-0.1 (preliminary calibration) at the beginning of our observations. [GCN OPS NOTE(14may13): Per author's request, the line "2013/02/15 01:38:40, i.e. about 7 min" was changed to "2013/02/15 01:43:21, i.e. about 12 min", due to a clock error correction.]

We detect the optical counterpart discovered by ROTSE (Zheng et al.; GCN 14205). In comparison with USNO-B1 and 2MASS, we derive the following magnitudes in the AB system: r' = 17.86 +/- 0.05 i' = 17.10 +/- 0.04 Z = 16.86 +/-0.04 J = 16.67 +/- 0.04 These magnitudes are not corrected for Galactic extinction in the direction of the GRB. Compared to the earlier observation at Palomar (Cenko et al; GCN 14209), our r band magnitude implies a temporal fade by >1 mag on a timescale of 2 hours, with a corresponding power law fade f ~ t^(-1.5) between 1 and 3 hours after the GRB. We thank the staff of the Observatorio Astronómico Nacional in San Pedro Mártir.

(Artemis/IRAP), Dereli, H. (Artemis/OCA), Atteia J.L. (IRAP-CNRS-OMP), Boer M. (UNS-CNRS-OCA), Klotz A. (IRAP-CNRS-OMP) report: We imaged the field of GRB 130215A detected by SWIFT (trigger 548760, D'Elia et al., GCN 14204) with the TAROT robotic telescope located at the European Southern Observatory, La Silla observatory, Chile. The observations started 15.5s after the GCN notice (704.3s after the SWIFT trigger). The elevation of the field decreased from 20 degrees above horizon and weather conditions were good. At the position reported by Zheng et al. (GCN 14205) we clearly detect the afterglow between 704s and 5481 seconds after the trigger. We also confirm the peak in the light curve around 750s post-trigger announced by Zheng et al. (GCN 14208). We obtained the following magnitudes, calibrated with three different USNO-B1 objects (statistical 3 sigma errors are of the order of 0.1-0.2), and not corrected for galactic extinction. MidTime (s) R mag 719 13.8 1192 14.4 1795 15.0 2723 15.7 4439 16.3 N.B. Galactic coordinates are lon=163.0747 lat=-39.7685 and the galactic extinction in R band is 0.3 magnitudes estimated from D.

Baumgartner (GSFC/UMBC), J. R. Cummings (GSFC/UMBC), V. D'Elia (ASDC), E. E. Fenimore (LANL), N. Gehrels (GSFC), H. A. Krimm (GSFC/USRA), A. Y. Lien (NASA/GSFC/ORAU), C. B. Markwardt (GSFC), D. M. Palmer (LANL), T. Sakamoto (AGU), G. Sato (ISAS), M. Stamatikos (OSU), J. Tueller (GSFC), T. N. Ukwatta (MSU) (i.e. the Swift-BAT team): Using the data set from T-239 to T+963 sec from recent telemetry downlinks, we report further analysis of BAT GRB 130215A (trigger #548760) (D'Elia, et al., GCN Circ. 14204). The BAT ground-calculated position is RA, Dec = 43.486, 13.387 deg which is RA(J2000) = 02h 53m 56.7s Dec(J2000) = +13d 23' 13.6" with an uncertainty of 1.5 arcmin, (radius, sys+stat, 90% containment). The partial coding was 8%. The mask-weighted light curve starts at ~T-10 sec, peaks at ~T+10 sec, and slowly returns to baseline at ~T+170 sec. T90 (15-350 keV) is 65.7 +- 10.8 sec (estimated error including systematics). The time-averaged spectrum from T-5.83 to T+73.38 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.59 +- 0.14. The fluence in the 15-150 keV band is 5.4 +- 0.5 x 10^-6 erg/cm2. The 1-sec peak photon flux measured from T+11.16 sec in the 15-150 keV band is 2.5 +- 0.7 ph/cm2/sec. All the quoted errors are at the 90% confidence level. The results of the batgrbproduct analysis are available at http://gcn.gsfc.nasa.gov/notices_s/548760/BA/ We note that the BAT trigger occurred during a telemetry downlink session during which the real-time TDRSS messages (that GCN uses) are buffered on-board until the end of the downlink. For this trigger the minimum bufferring delay to the ground was 692 sec.

The angle from the Fermi LAT boresight is 86 degrees. The GBM light curve consists of single FRED like pulse with a duration (T90) of about 140 s (50-300 keV). The time-averaged spectrum from T0-7.0 s to T0+124 s is adequately fit by a Band function with Epeak= 155 +/- 63 keV, alpha = -1.0 +/- 0.2 and beta = -1.60 +/- 0.03. The event fluence (10-1000 keV) in this time interval is (2.02 +/- 0.05)E-05 erg/cm^2. The 1-sec peak photon flux measured starting from T0+10.56 s in the 10-1000 keV band is 3.5 +/- 0.3 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."

Greiner (all MPE Garching), and D. A. Kann (TLS Tautenburg) report on behalf of the GROND team: We observed the field of GRB 130215A (Swift trigger 548760; D'Elia et al., GCN 14204) simultaneously in g'r'i'z'JHK with GROND (Greiner et al. 2008, PASP 120, 405) mounted at the 2.2 m MPG/ESO telescope at La Silla Observatory (Chile). Observations started at 00:50 UT on 16.02.13, 23.3 hrs after the GRB trigger They were performed at an average seeing of 1".8 and at an average airmass of 1.98. We detect a point source in most bands at position: RA (J2000) = 02:54:00.70 Dec. (J2000) = +13:23:43.4 with an uncertainty of 0".4, close to the position reported by Zheng et al. (GCN 14205). Based on the first 13 min of total exposures in g'r'i'z' and 14 min in JHK, we estimate preliminary magnitudes (all in AB system) of g' = 21.0 +- 0.1 mag, r' = 20.5 +-0.1 mag, i' = 20.2 +- 0.1 mag, z' = 19.9 +- 0.1 mag, J = 19.4 +- 0.2 mag, H = 19.0 +- 0.1 mag and K > 18.0 mag. Given magnitudes are calibrated against GROND zeropoints as well as 2MASS field stars and are not corrected for the expected Galactic foreground extinction corresponding to a reddening of E_(B-V)=0.16 mag in the direction of the burst (Schlegel et al. 1998).

Perley (Caltech) reports: I observed the location of GRB 130215A (D'Elia et al., GCN 14204) with the Wide-Field Infrared Camera (WIRC) on the Palomar 200-inch telescope on 2013-02-16 UT between 02:14 and 03:17. A series of nine 60-second images each were taken in Ks, J, and H filters, followed by a second series in Ks. High winds were present and seeing significantly degraded over the course of the observations. The optical/NIR afterglow (Zheng et al., GCN 14205, Covino et al., GCN 14211) is well-detected in a preliminary reduction of the Ks-band images. Photometry (calibrated relative to 2MASS standards in the field) gives the following magnitudes: t_mid=24.89 hours : Ks = 17.23 +/- 0.05 mag (19.07 AB) t_mid=25.65 hours : Ks = 17.34 +/- 0.08 mag (19.18 AB) Further observations are planned.

Perley (Caltech) reports: I re-observed the location of GRB 130215A with the Wide-Field Infrared Camera (WIRC) on the Palomar 200-inch telescope on 2013-02-17 UT between 02:09 and 02:37 and between 04:29 and 04:56. Images were again taken in J, H, and Ks-bands; transmission and seeing conditions were good. The NIR afterglow remains well-detected in the most recent images. Photometry of the Ks-band images gives the following magnitudes (Vega): t_mid=48.75 hours : Ks = 17.57 +/- 0.05 mag t_mid=51.07 hours : Ks = 17.60 +/- 0.07 mag Relative to the previous night (GCN 14222), these observations show remarkably little fading (decay index alpha~0.4 between 25-50 hours, compared to alpha~1.5 earlier; Butler et al., GCN 14212). This could indicate contribution from a bright host galaxy, but no obvious extension of the source is seen (in 1" seeing). Alternatively it could indicate a bump, plateau or flare in the light curve. Further observations with WIRC are not planned, but observations elsewhere are encouraged to constrain further evolution of the afterglow.

From 2013/02 18.13 to 2013/02 18.21UTC (73.5 to 75.5 hours after the BAT trigger), we obtained a total of 1.40 hours exposure in the r' and i' bands and 0.53 hours of exposure in the Z, Y, J, and H bands. In comparison with USNO-B1 and 2MASS, we derive the following AB magnitudes, not corrected for Galactic extinction in the direction of the GRB, for the afterglow: r' 21.92 +/- 0.09 i' 20.92 +/- 0.07 Z 20.21 +/- 0.12 Y 20.38 +/- 0.15 J 20.37 +/- 0.13 H 19.59 +/- 0.11 We thank the staff of the Observatorio Astronmico Nacional in San Pedro Mrtir.

Cenko (UC Berkeley), and D. A. Brown (Syracuse) report on behalf of a larger collaboration: We have imaged the 3-sigma Swift BAT error circle (S. Barthelmy, GCN 14214) of GRB130215A (Swift548760, S. Barthelmy, GCN 14204) with the Palomar 48 inch Oschin telescope (P48) as part of the Palomar Transient Factory (PTF). Images were obtained in the Mould R filter on 2013-02-15 at 02:35:05 and 04:05:52 UTC, 1.1 and 2.6 hours after the trigger. We detect a fading point source that is absent in the USNO B-1 catalog at magnitudes of 16.38 and 17.59 at RA(J2000) = 2h 54m 00.73s DEC(J2000) = +13d 23' 43.0" , matching the ROTSE-IIIb position (GCN 14205, Zheng & Flewelling). Assuming a power-law decay, these two P48 observations give us an index alpha=-1.25, consistent with the index of alpha=-1.24 reported by ROTSE analysis (GCN 14208, Zheng et al.).

Makishima (Univ. of Tokyo), on behalf of the Suzaku WAM team, report: The long GRB 130215A (Elia et al GCN14204; George et al GCN14219) was detected by the the Suzaku Wide-band All-sky Monitor (WAM) which covers an energy range of 50 keV - 5 MeV at 01:31:25.437 UT (=T0). The observed light curve shows a single peak with a duration (T90) of about 46.0 seconds. The fluence in 100 - 1000 keV was 1.04 (+0.13/-0.13) x 10^-5 erg/cm^2. The 1-s peak flux measured from T0+1 s was 0.69 (+0.28/-0.36) photons/cm^2/s in the same energy range. Preliminary result shows that the time-averaged spectrum from T0-7 s to T0+55 s is well fitted by a single power-law with a photon index of 1.61 (+0.08/-0.07) (chi2/d.o.f = 13.9/14). All the quoted errors are at statistical 90% confidence level, in which the systematic uncertainties are not included.

Malesani, J. Hjorth (DARK/NBI), P. Jakobsson (U. Iceland), O.E. Hartoog (U. Amsterdam) report on behalf of a larger collaboration: We have observed the optical counterpart of GRB 130215A (D'Elia et al., GCN 14204, Zheng et al., GCN 14205) with the 10.4 m GTC telescope equipped with the OSIRIS imager and spectrograph. A spectroscopic observation was performed on 12 March 2013 at a mean time of 20:52 UT, 25.8 days after the burst, corresponding to 16.2 days after the burst in the rest frame, considering a redshift of z=0.597 (Cucchiara et al. GCN 14207). The total exposure was 3x1200s using a low resolution grating (R~600) covering a wavelength range 5000-10000 A. Due to its current location, observations had to be carried out at high airmass, between 1.6 and 2.2. There were thin cirrus but seeing was very good, at 0.6". At this epoch, the spectrum presents undulations typical of SN spectra, including a prominent bump at ~8200 A. Using SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we have compared the spectrum to a series of SN templates. The spectrum gives a good match to a number of SNe Ic, including broad-lined and normal events such as SN 2002ap and SN 1994I, around maximum light or slightly after. By leaving the redshift unconstrained we obtain the same template fit and derive a redshift of z=0.58+/-0.02, fully consistent with the absorption line redshift. We acknowledge excellent support from the GTC staff, in particular Carlos A. Alvarez Iglesias.
