Circular_text TITLE: GCN CIRCULAR NUMBER: 18893 SUBJECT: GRB 160119A: Swift detection of a burst DATE: 16/01/19 03:18:51 GMT FROM: David Palmer at LANL F. E. Marshall (NASA/GSFC), D. N. Burrows (PSU), J. A. Kennea (PSU), H. A. Krimm (CRESST/GSFC/USRA), K. L. Page (U Leicester) and D. M. Palmer (LANL) report on behalf of the Swift Team: At 03:06:08 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 160119A (trigger=671014). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 211.893, +20.474 which is RA(J2000) = 14h 07m 34s Dec(J2000) = +20d 28' 28" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows low level variability followed by a peak from T+120 to T+180. The peak count rate was ~3000 counts/sec (15-350 keV), at ~142 sec after the trigger. The XRT began observing the field at 03:08:48.0 UT, 159.8 seconds after the BAT trigger. Using promptly downlinked data we find a bright, fading, uncatalogued X-ray source located at RA, Dec 211.92111, 20.46161 which is equivalent to: RA(J2000) = 14h 07m 41.07s Dec(J2000) = +20d 27' 41.8" with an uncertainty of 3.8 arcseconds (radius, 90% containment). This location is 104 arcseconds from the BAT onboard position, within the BAT error circle. This position may be improved as more data are received; the latest position is available at http://www.swift.ac.uk/sper. A power-law fit to a spectrum formed from promptly downlinked event data gives a column density in excess of the Galactic value (3.08 x 10^20 cm^-2, Willingale et al. 2013), with an excess column of 3.4 (+2.60/-1.22) x 10^21 cm^-2 (90% confidence). The initial flux in the 0.1 s image was 2.75e-08 erg cm^-2 s^-1 (0.2-10 keV). UVOT took a finding chart exposure of 150 seconds with the White filter starting 168 seconds after the BAT trigger. No credible afterglow candidate has been found in the initial data products. The 2.7'x2.7' sub-image covers 100% of the XRT error circle. The typical 3-sigma upper limit has been about 19.6 mag. The 8'x8' region for the list of sources generated on-board covers 100% of the XRT error circle. The list of sources is typically complete to about 18 mag. No correction has been made for the expected extinction corresponding to E(B-V) of 0.03. Burst Advocate for this burst is F. E. Marshall (marshall AT milkyway.gsfc.nasa.gov). 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.)

Circular_text TITLE: GCN CIRCULAR NUMBER: 18895 SUBJECT: GRB 160119A: NOT and GTC afterglow candidate DATE: 16/01/19 05:06:13 GMT FROM: Daniele Malesani at Dark Cosmology Centre, Niels Bohr Inst D. Malesani (DARK/NBI), A. de Ugarte Postigo (IAA-CSIC and DARK/NBI), D. Xu (NAO/CAS), C.E. Martinez-Vazquez (IAC-ULL), A. Tejero (GTC), S. Geier (GTC), C.C. Thoene (IAA-CSIC), P. Jakobsson (Univ. Iceland) report on behalf of a larger collaboration. We observed the field of GRB 160119A (Marshall et al., GCN 18893) with the Nordic Optical Telescope (NOT) equipped with the ALFOSC camera. Observations were carried out in the SDSS r and i bands, starting on 2015 Jan 19.151 UT (31 min after the GRB trigger). We also observed the same field using the Gran Telescopio Canarias (GTC), equipped with OSIRIS, starting on Jan 19.164 UT (50 min after the GRB trigger), also in the r and i bands. Compatible with the current XRT localization (3.6" radius, SPER-based; http://www.swift.ac.uk/xrt_positions/), we detect a single, faint optical source, at coordinates (J2000): RA = 14:07:41.35 Dec = +20:27:40.1 with an uncertainty of <0.5". Using nearby stars from the SDSS catalog, we measure from the NOT image a magnitude r = 22.75 +- 0.15 (AB). This magnitude measurement is affected by the extended glare of a nearby bright star, making background subtraction less accurate than normal. This object is also seen, faintly, in the short GTC images (30-60 s exposure). The object seems marginally brighter than the SDSS detection limit. However, despite ~20 min time difference between the NOT and GTC data, we do not measure obvious variability between the two epochs, as it is common among GRB afterglows close to the trigger. Further observations will be necessary to ascertain the relation of this object with the GRB.

Beardmore and P.A. Evans (U. Leicester) report on behalf of the Swift-XRT team. Using 1310 s of XRT Photon Counting mode data and 1 UVOT images for GRB 160119A, we find an astrometrically corrected X-ray position (using the XRT-UVOT alignment and matching UVOT field sources to the USNO-B1 catalogue): RA, Dec = 211.92183, +20.46094 which is equivalent to: RA (J2000): 14h 07m 41.24s Dec (J2000): +20d 27' 39.4" with an uncertainty of 1.7 arcsec (radius, 90% confidence). This position may be improved as more data are received. The latest position can be viewed at http://www.swift.ac.uk/xrt_positions. Position enhancement is described by Goad et al.

D'Avanzo (INAF-OAB), D.N. Burrows (PSU), T.G.R. Roegiers (PSU), L.M. McCauley (PSU), J.P. Osborne (U. Leicester), K.L. Page (U. Leicester), C. Pagani (U. Leicester), V. D'Elia (ASDC) and F.E. Marshall report on behalf of the Swift-XRT team: We have analysed 8.4 ks of XRT data for GRB 160119A (Marshall et al. GCN Circ. 18893), from 149 s to 18.2 ks after the BAT trigger. The data comprise 456 s in Windowed Timing (WT) mode (the first 9 s were taken while Swift was slewing) with the remainder in Photon Counting (PC) mode. The enhanced XRT position for this burst was given by Goad et al. (GCN Circ. 18896). The late-time light curve (from T0+4.9 ks) can be modelled with a power-law decay with a decay index of alpha=0.59 (+/-0.11). A spectrum formed from the WT mode data can be fitted with an absorbed power-law with a photon spectral index of 1.86 (+/-0.05). The best-fitting absorption column is 2.57 (+0.23, -0.22) x 10^21 cm^-2, in excess of the Galactic value of 3.1 x 10^20 cm^-2 (Willingale et al. 2013). The PC mode spectrum has a photon index of 2.11 (+/-0.11) and a best-fitting absorption column of 1.9 (+/-0.3) x 10^21 cm^-2. The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 3.3 x 10^-11 (4.7 x 10^-11) erg cm^-2 count^-1. A summary of the PC-mode spectrum is thus: Total column: 1.9 (+/-0.3) x 10^21 cm^-2 Galactic foreground: 3.1 x 10^20 cm^-2 Excess significance: 8.0 sigma Photon index: 2.11 (+/-0.11) If the light curve continues to decay with a power-law decay index of 0.59, the count rate at T+24 hours will be 0.056 count s^-1, corresponding to an observed (unabsorbed) 0.3-10 keV flux of 1.8 x 10^-12 (2.6 x 10^-12) erg cm^-2 s^-1. The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/00671014. This circular is an official product of the Swift-XRT team.

Barthelmy (GSFC), J. R. Cummings (GSFC/UMBC), N. Gehrels (GSFC), H. A. Krimm (GSFC/USRA), A. Y. Lien (GSFC/UMBC), C. B. Markwardt (GSFC), F. E. Marshall (NASA/GSFC), D. M. Palmer (LANL), T. Sakamoto (AGU), T. N. Ukwatta (LANL) (i.e. the Swift-BAT team): Using the data set from T-239 to T+963 sec from the recent telemetry downlink, we report further analysis of BAT GRB 160119A (trigger #671014) (Marshall, et al., GCN Circ. 18893). The BAT ground-calculated position is RA, Dec = 211.916, 20.453 deg which is RA(J2000) = 14h 07m 39.8s Dec(J2000) = +20d 27' 09.1" with an uncertainty of 2.0 arcmin, (radius, sys+stat, 90% containment). The partial coding was 77%. The mask-weighted light curve shows some low-level activity from about T+20 sec to T+100 sec. This is followed by a single main peak starting at T+110 sec, with a broad peak from T+140 to T+155 sec, and a slow decay out to T+200 sec. T90 (15-350 keV) is 116 +- 14 sec (estimated error including systematics). The time-averaged spectrum from T+32.62 to T+190.39 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.68 +- 0.05. The fluence in the 15-150 keV band is 7.1 +- 0.2 x 10^-6 erg/cm2. The 1-sec peak photon flux measured from T+146.06 sec in the 15-150 keV band is 2.9 +- 0.2 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

We identified the source reported by Malesani et al., GCN 18895. In comparison with the SDSS DR9 and 2MASS catalogs, we obtain the following detections and upper limits (3-sigma): r 23.78 +/- 0.28 i 23.26 +/- 0.17 z > 20.78 These magnitudes are in the AB system and are not corrected for Galactic extinction in the direction of the GRB.

Knust, J. Greiner (all MPE Garching), and D. A. Kann (TLS Tautenburg) report on behalf of the GROND team: We observed the field of GRB 160119A (Swift trigger 671014; Marshall et al., GCN #18893) simultaneously in g'r'i'z'JHK with GROND (Greiner et al. 2008, PASP 120, 405) mounted at the 2.2 m MPG telescope at ESO La Silla Observatory (Chile). Observations started at 07:53 UT on 2016-01-19, about 4.8 hours after the GRB trigger. Our images were performed at an average seeing of 1.8" and at an average airmass of 2.0. Based on 19 min of total exposure in g'r'i'z' and 16 min in JHK at a midtime of 08:38 UT on 2016-01-19, we estimate the detection and upper-limit magnitudes (all in the AB system): g' > 23.9 mag, r' = 23.6 +- 0.2 mag, i' = 22.9 +- 0.2 mag, z' = 22.5 +- 0.2 mag, J > 20.5 mag, H > 20.2 mag, and K > 19.1 mag. Our observation was about 4.8 hours later than the NOT followup observed by Malesani et al. (GCN #18895), and about 0.2 hours earlier than the RATIR observation by Cucchiara et al. (GCN #18901). The fading of r'-band magnitudes between NOT and GROND is about 0.85 mag, and within the uncertainties between GROND and RATIR. The decline rate is about 0.18 mag/hr, which confirms the afterglow nature. The given magnitudes are derived based on calibrating the images against SDSS and 2MASS field stars and are not corrected for the Galactic foreground extinction corresponding to a reddening of E(B-V)= 0.03 mag in the direction of the burst (Schlafly & Finkbeiner 2011).

Oates (IAA-CSIC), Martin Jelinek (Astronomical Institute ASU-AVCR Ondrejov) and A. J.Castro-Tirado (IAA-CSIC & ISA-UMA), on behalf of a larger collaboration, report: "The 60 cm BOOTES-2/TELMA robotic telescope (Malaga, Spain) automatically responded to the Swift trigger of GRB 160119A (Marshall et al., GCN 18893). The first unfiltered images where obtained at 03:07:59 (111 seconds after the burst, 9.44 seconds after receiving the GCN alert). No credible source is found when combining the first 40 unfiltered images of 3 seconds exposure. The combined image ranges from 03:07:59 UT - 03:10:28 UT (1.85-4.33 minutes after the burst) and results in a limiting magnitude of 19.5 when compared to SDSS-R6 r filter catalog. We also observed the field using the i filter, no credible source is found either when combining 6x60s exposures. The combined image ranges from 03:16:54 UT - 03:40:01 UT (10.7-33.9 minutes after the burst) and results in a limiting magnitude of 18.5 when compared to SDDS-R6 catalog."

Malesani (DARK/NBI), D. Xu (NAOC/CAS), P. Jakobsson (Univ. Iceland), C.E. Martinez-Vazquez (IAC-ULL), S. Murabito (IAC-ULL) report on behalf of a larger collaboration: We observed again the field of GRB 160119A (Marshall et al., GCN 18893) with the Nordic Optical Telescope (NOT) equipped with the AlFOSC camera. Observations start on January 20.14 UT (1.01 days after the GRB) and consisted of 3x600 s in the SDSS r band. No object is detected at the position of the candidate afterglow (Malesani et al., GCN 18895; Cucchiara et al., GCN 18901; Chen et al., GCN 18902), down to a limiting magnitude r > 23.8 AB (3 sigma), calibrated against nearby SDSS stars. Compared to our previous observation (Malesani et al., GCN 18895), the new measurement conclusively establishes fading, thus confirming that this source is the afterglow of GRB 160119A, as already suggested by Chen et al. (GCN 18902).

Aptekar, D. Frederiks, P. Oleynik, M. Ulanov, D. Svinkin, A. Tsvetkova, A.Lysenko, and T. Cline, on behalf of the Konus-Wind team, report: The long-duration GRB 160119A (Swift-BAT trigger #671014: Marshall, et al., GCN Circ. 18893, Stamatikos, et al., GCN Circ. 18899) was detected by Konus-Wind in the waiting mode. The burst light curve shows a weak count rate increase starting from ~T0(BAT)+9 s. The main phase of the event consists of a single peak from ~T0(BAT)+120 s to ~T0(BAT)+175 s. As calculated from the Bayesian block division, the total duration of the burst is ~215 s. The K-W light curve of this burst is available at http://www.ioffe.rssi.ru/LEA/GRBs/GRB160119A/ As observed by Konus-Wind, the burst had a fluence of 1.68(-0.18,+0.19)x10^-5 erg/cm2 and a 2.944-s peak flux, measured from ~T0(BAT)+144.3 s, of 6.39(-0.85,+0.89)x10^-7 erg/cm2/s (both in the 20 - 1200 keV energy range). Modelling the K-W 3-channel time-integrated spectrum (measured from ~T0(BAT)+8.9 s to ~T0(BAT)+223.8 s) by the cutoff power law yields the following model parameters: the photon index alpha = -1.73(-0.12,+0.15), and the peak energy Ep = 189(-53,+231) keV. Modelling the 3-channel spectrum near the peak count rate (from ~T0(BAT)+138.4 s to ~T0(BAT)+150.2 s) by the cutoff power law yields the following model parameters: the photon index alpha = -1.16(-0.13,+0.15), and the peak energy Ep = 187(-25,+34) keV. All the quoted errors are estimated at the 1 sigma confidence level. All the presented results are preliminary.
