Circular_text TITLE: GCN CIRCULAR NUMBER: 21214 SUBJECT: GRB 170607A: Swift detection of a burst with a bright optical counterpart DATE: 17/06/07 23:32:47 GMT FROM: David Palmer at LANL A. D'Ai (INAF-IASFPA), D. N. Burrows (PSU), A. Cholden-Brown (PSU), V. D'Elia (ASDC), J. A. Kennea (PSU), N. P. M. Kuin (UCL-MSSL), F. E. Marshall (NASA/GSFC), D. M. Palmer (LANL), B. Sbarufatti (INAF-OAB/PSU) and M. H. Siegel (PSU) report on behalf of the Swift Team: At 23:21:33 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 170607A (trigger=756284). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 7.343, +9.238 which is RA(J2000) = 00h 29m 22s Dec(J2000) = +09d 14' 16" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a single FRED structure with a duration of about 40 sec. The peak count rate was ~4000 counts/sec (15-350 keV), at ~1 sec after the trigger. The XRT began observing the field at 23:22:47.1 UT, 73.4 seconds after the BAT trigger. XRT found a bright, uncatalogued X-ray source located at RA, Dec 7.3655, 9.2425 which is equivalent to: RA(J2000) = +00h 29m 27.72s Dec(J2000) = +09d 14' 33.0" with an uncertainty of 4.8 arcseconds (radius, 90% containment). This location is 81 arcseconds from the BAT onboard position, within the BAT error circle. No event data are yet available to determine the column density using X-ray spectroscopy. The initial flux in the 2.5 s image was 5.32e-09 erg cm^-2 s^-1 (0.2-10 keV). UVOT took a finding chart exposure of 150 seconds with the White filter starting 83 seconds after the BAT trigger. There is a candidate afterglow in the rapidly available 2.7'x2.7' sub-image at RA(J2000) = 00:29:27.80 = 7.36582 DEC(J2000) = +09:14:36.2 = 9.24339 with a 90%-confidence error radius of about 0.61 arc sec. This position is 3.4 arc sec. from the center of the XRT error circle. The estimated magnitude is 15.90 with a 1-sigma error of about 0.14. No correction has been made for the expected extinction corresponding to E(B-V) of 0.04. Burst Advocate for this burst is A. D'Ai (antonino.dai AT ifc.inaf.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.)

Goad and J.P. Osborne (U. Leicester) report on behalf of the Swift-XRT team. Using 1379 s of XRT Photon Counting mode data and 1 UVOT images for GRB 170607A, 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 = 7.36612, +9.24329 which is equivalent to: RA (J2000): 00h 29m 27.87s Dec (J2000): +09d 14' 35.8" 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. (2007, A&A, 476, 1401) and Evans et al. (2009, MNRAS, 397, 1177). This circular was automatically generated, and is an official product of the Swift-XRT team.

Cholden-Brown (PSU), A.P. Beardmore (U. Leicester), P.A. Evans (U. Leicester), S.L. Gibson (U. Leicester), A. Melandri (INAF-OAB), P. D'Avanzo (INAF-OAB), S. J. LaPorte (PSU) and A. D'Ai report on behalf of the Swift-XRT team: We have analysed 7.5 ks of XRT data for GRB 170607A (D'Ai et al. GCN Circ. 21214), from 63 s to 19.1 ks after the BAT trigger. The data comprise 395 s in Windowed Timing (WT) mode (the first 8 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 Beardmore et al. (GCN Circ. 21215). The late-time light curve (from T0+5.1 ks) can be modelled with a power-law decay with a decay index of alpha=0.54 (+/-0.09). A spectrum formed from the WT mode data can be fitted with an absorbed power-law with a photon spectral index of 2.003 (+0.038, -0.019). The best-fitting absorption column is consistent with the Galactic value of 4.4 x 10^20 cm^-2 (Willingale et al. 2013). The PC mode spectrum has a photon index of 1.92 (+/-0.08) and a best-fitting absorption column of 7.1 (+1.9, -1.8) x 10^20 cm^-2. The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 3.4 x 10^-11 (3.9 x 10^-11) erg cm^-2 count^-1. A summary of the PC-mode spectrum is thus: Total column: 7.1 (+1.9, -1.8) x 10^20 cm^-2 Galactic foreground: 4.4 x 10^20 cm^-2 Excess significance: 2.5 sigma Photon index: 1.92 (+/-0.08) If the light curve continues to decay with a power-law decay index of 0.54, the count rate at T+24 hours will be 0.13 count s^-1, corresponding to an observed (unabsorbed) 0.3-10 keV flux of 4.3 x 10^-12 (5.0 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/00756284. This circular is an official product of the Swift-XRT team.

Heintz (Univ. of Iceland and DARK/NBI), A. de Ugarte Postigo (IAA-CSIC, DARK/NBI), and J. Claesen (NOT) report on behalf of a larger collaboration, We have observed the field of GRB 170607A (D’Ai et al., GCN 21214) with the 2.5m Nordic Optical Telescope at La Palma, Spain. The observations consisted of 3x180s in the Sloan g-, r- and i-bands and were carried out at a mid-time of 04:23:59 UT (i.e. 5.03 hr after the burst). The bright afterglow is well detected in all the individual frames. From the reduced and combined images we measure magnitudes of: g(AB) = 18.57 +/- 0.08 mag r(AB) = 18.36 +/- 0.06 mag i(AB) = 18.22 +/- 0.05 mag calibrated against nearby SDSS field stars. We also note the presence of a galaxy at a photometric redshift of 0.632 in the SDSS images, close to the location of the burst, which we identify as a host galaxy candidate.

Meegan (UAH) report on behalf of the Fermi GBM Team: "At 23:17:59.57 UT on 07 June 2017, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 170607A (trigger 518570284 / 170607971), which was also detected by the Swift/BAT (D'Ai et al. 2017, GCN 21214). The GBM on-ground location is consistent with the Swift position. The angle from the Fermi LAT boresight at the GBM trigger time is 100 degrees. The GBM light curve consists of a sharp peak with a duration (T90) of about 23 s (50-300 keV). The time-averaged spectrum from T0-2.4 s to T0+14.0 s is adequately fit by a power law function with an exponential high-energy cutoff. The power law index is -1.40 +/- 0.04 and the cutoff energy, parameterized as Epeak, is 154 +/- 13 keV. The event fluence (10-1000 keV) in this time interval is (9.6 +/- 0.3)E-06 erg/cm^2. The 1-sec peak photon flux measured starting from T0+2.1 s in the 10-1000 keV band is 15.5 +/- 0.6 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."

D'Ai (INAF-IASFPA) report on behalf of the Swift/UVOT team: The Swift/UVOT began settled observations of the field of GRB 170607A 84 s after the BAT trigger (D'Ai et al., GCN Circ. 21214). GRB 170607A was also triggered by Fermi GBM (Hamburg and Meegan GCN Circ. 21218) We detect a fading afterglow consistent with the position given by XRT (Beardmore et al., GCN Circ. 21215) and ground-based optical detections (Heintz et al., GCN Circ. 21217; Lipunov et al., GCN Circ. 21219). The preliminary UVOT position is: RA (J2000) = 00:29:27.82 = 7.36591 (deg.) Dec (J2000) = +09:14:36.0 = 9.24334 (deg.) with an estimated uncertainty of 0.42 arc sec. (radius, 90% confidence).

E. Heintz (Univ. of Iceland and DARK/NBI), A. de Ugarte Postigo (IAA-CSIC, DARK/NBI), and S. Schulze (Weizmann Institute) report on behalf of a larger collaboration, In our previous GCN (Heintz et al., GCN 21217) we reported a possible SDSS host galaxy at z=0.632. We note, however, that this identification was incorrect, as this galaxy lies a few arcseconds away from the GRB afterglow. However, further analysis of SDSS and Pan-STARRS images do show a possible host galaxy lying just 0.”8 of the afterglow position as measured by UVOT, with a faintness around the Pan-STARRS r-band detection limit.

Stamatikos (OSU), (i.e. the Swift-BAT team): Using the data set from T-240 to T+962 sec from the recent telemetry downlink, we report further analysis of BAT GRB 170607A (trigger #756284) (D'Ai et al., GCN Circ. 21214). The BAT ground-calculated position is RA, Dec = 7.358, 9.225 deg which is RA(J2000) = 00h 29m 26.0s Dec(J2000) = +09d 13' 30.8" with an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment). The partial coding was 57%. The mask-weighted light curve show two prominent pulses. The first pulse starts before it came into the BAT FOV at T0-217.9 s during a preplanned spacecraft slew. It peaks at ~T0-210 s and ends at ~T0-190 s. The second pulse starts at ~T0-10 s, peaks at T0, and ends at ~T0+40 s, with a tail lasting till ~T0+140 s. The time-averaged spectrum from T0-207.896 to T0+144.104 s is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.61 +- 0.07. The fluence in the 15-150 keV band is 7.5 +- 0.3 x 10^-6 erg/cm2. All the quoted errors are at the 90% confidence level.

GCN 21237) using OSIRIS at the 10.4m GTC telescope. Observation consisted of 3x900s using grism R1000R, which covers the range between 5100 and 10100 Å, at a mean epoch of 10.1955 June 2017 UT (2.2222 days after the GRB). The acquisition image still shows a bright afterglow at r(AB) = 20.70 +/- 0.05 mag, as compared to SDSS field stars. In spite of the strong contribution from the afterglow, no clear absorption features can be detected in this spectral range. However, there are strong emission lines due to [OII], [OIII], and H-beta at a common redshift of 0.557, which we identify as the redshift of the GRB.

The burst signal was seen only by the SGM instrument. The light curve of the SGM shows two distinct peaks. The first peak starts at T+2 sec, peaks at T+4 sec and ends at T+8 sec. The second peak starts at T+210 sec, peaks at T+215 sec and ends at T+230 sec. The T90 durations of the first peak and the second peak measured by the SGM data separately are 4.0 +- 0.5 sec and 10.5 +- 0.8 sec (40-1000 keV). The light curve is available at http://cgbm.calet.jp/cgbm_trigger/flight/1180912206/ The CALET data used in this analysis are provided by the Waseda CALET Operation Center located at the Waseda University.

Scaife (Manchester) The AMI Large Array robotically triggered on the Swift alert for GRB 170607A (D'Ai et al., GCN 21214) as part of the 4pisky program, and subsequent follow up observations were obtained up to 10 days post-burst. Our observations at 15 GHz on 2016 Jun 08.12, Jun 10.29, Jun 12.28 and Jun 16.24 (UT) do not reveal any radio source at the XRT location (Beardmore et al., GCN 21215), with 3sigma upper limits of 318 uJy, 108 uJy, 117 uJy and 117 uJy respectively. We thank the AMI staff for scheduling these observations. The AMI-GRB database is a log of all GRB follow up observations with the AMI, and is available at http://4pisky.org/ami-grb/.
