  At 22:07:25 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 090621B (trigger=355359). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 313.432, +69.013 which is

     RA(J2000)  =  20h 53m 44s
     Dec(J2000) = +69d 00' 48"
  

  with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows a single spike with a duration less than 128 millisec. The peak count rate was ~7000 counts/sec (15-350 keV), at ~0 sec after the trigger.
  The XRT began observing the field at 22:08:36UT, 70.7 s after the BAT trigger. In promptly downlinked data, XRT found a faint uncatalogued source at RA, Dec (J2000) = 313.4700, 69.0282, which is

  RA = 20h 53m 52.8s
  Dec = +69d 01' 41.5"
  

  with an uncertainty of 8.0 arcseconds (radius, 90% containment). This location is 73 arcseconds from the BAT onboard position, within the BAT error circle.
  UVOT took a finding chart exposure of nominal 150 seconds with the White filter starting 76 seconds after the BAT trigger. No credible afterglow candidate has been found in the initial data products at the XRT position. Data from the 2.7'x2.7' sub-image are not available at this time. The 8'x8' region for the list of sources generated on-board covers 100% of the BAT 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 0.43 (Schlegel et al. 1998).
  Burst Advocate for this burst is P.A. Curran (pac AT mssl.ucl.ac.uk). 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.)

• GCN Circular #9547
  A.J. Levan (U. Warwick), P. Curran (MSSL), K. Wiersema (U. Leicester) and P. Groot (Nijmegen) report:
  "We observed the location of the short GRB 090621B (Curran et al. GCN 9545) with the WHT, beginning at 23:48:33 UT. Observations were obtained in the i-band, with a total exposure time of 1800s. Inside the XRT error box we find a faint object at

  RA = 20 53 53.07 
  Dec = +69 01 40.8
  

  with errors of approximately 0.5" in each axis. The object is significantly fainter than the DSSII limit, and shows no obvious variability between the first and last exposures (taken ~1.7 and ~2.3 hours post burst). Given the relatively high foreground extinction the probability of a chance alignment within the XRT error box is non-trivial. Hence we are unable to make strong statements about the association of this source with GRB 090621B at this stage."

  report:
  We observed the field of the Swift-BAT GRB 090621B (Curran et al., GCN9545) with Russian-Turkish 1.5-m telescope (RTT150, Bakirlitepe, TUBITAK National Observatory, Turkey), starting at 21 Jun, 22:52:55 UT, i.e. approximately 45 minutes after the burst, using TFOSC.
  We made 3x300s exposures in Rc band. On combined image we do not detect any new source inside the XRT error circle (Curran et al., GCN 9545) besides the source reported by Levan et. al. (GCN 9547), which is detected only marginally. There is also one more brighter point-like source (RA=20:53:51.25, DEC=+69:01:37.4, J2000) outside but close to the edge of XRT error circle. Using USNO-B1 stars we estimate its magnitude as m_Rc=21.8+/-0.06. The limiting magnitude of combined image is m_Rc ~23.6.

• GCN Circular #9550
  A.P. Beardmore, K.L. Page (U. Leicester) and P.A. Curran (UCL-MSSL) report on behalf of the Swift-XRT team:
  We have analysed five orbits of Swift-XRT photon counting (PC) mode data from GRB 090621B (Curran et al., GCN Circ. 9545), spanning the interval T+80 s to T+19.5 ks after the trigger. In 10.0 ks we find a refined XRT position of RA, Dec = 313.47049, 69.02845, which is equivalent to

  RA (J2000) =  20:53:52.92
  Dec(J2000) = +69:01:42.4
  

  with an uncertainty of 4.0 arcsec (90% containment). This position is 1.2 arcsec from the XRT position quoted in GCN Circ. 9545.
  The X-ray light-curve shows a faint, fading source with a decay index of 0.61 +/- 0.19. If the source continues to decay at the same rate we predict an XRT count rate of 8.6e-4 count s^-1 at T+24 hours.
  The PC mode spectrum from T+80 s to T+17.1 ks can be fit by an absorbed powerlaw with a photon index of 1.47+/-0.66, assuming a Galactic column density of 1.9e21cm^-2 in the direction of the burst. The observed (unabsorbed) 0.3-10keV flux for this model is 3.8e-13 (4.5e-13) erg cm^-2 s^-1.

  Using the data set from T-239 to T+963 sec from the recent telemetry downlink, we report further analysis of BAT short hard burst GRB 090621B (trigger #355359) (Curran, et al., GCN Circ. 9545). The BAT ground-calculated position is RA, Dec = 313.455, 69.034 deg, which is

     RA(J2000)  =  20h 53m 49.3s 
     Dec(J2000) = +69d 02' 02.9" 
  

  with an uncertainty of 1.7 arcmin, (radius, sys+stat, 90% containment). The partial coding was 69%.
  The mask-weighted light curve shows a single peak starting a ~T+0 sec and ending at ~T+0.2 sec. There is a 2.5-sigma hint of extended emission from ~T+150 to ~T+240 sec. T90 (15-350 keV) is 0.14 +- 0.04 sec (estimated error including systematics).
  The time-averaged spectrum from T-0.028 to T+0.148 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 0.82 +- 0.23. The fluence in the 15-150 keV band is 7.0 +- 1.0 x 10^-8 erg/cm2. The 1-sec peak photon flux measured from T-0.44 sec in the 15-150 keV band is 3.9 +- 0.5 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

  P.A. Curran (MSSL-UCL) reports on behalf of the Swift/UVOT team:
  The Swift/UVOT began settled observations of the field of GRB 090621B 76s after the BAT trigger (Curran et al., GCN 9545). No optical afterglow consistent with the refined XRT position (Beardmore et al., GCN 9550) or the optical source observed by Levan et al. (GCN 9547) is detected in the UVOT exposures.
  Preliminary 3-sigma upper limits using the UVOT photometric system (Poole et al. 2008, MNRAS, 383, 627) for the first exposures are:

  Filter	T_start(s) T_stop(s)  Exp(s)  Mag

  The values quoted above are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.44 in the direction of the burst (Schlegel et al. 1998).

  S. B. Cenko (UC Berkeley), A. J. Levan (U. Warwick), M. M. Kasliwal, S. R. Kulkarni (Caltech) report on behalf of a larger collaboration:
  We have imaged the field of the short GRB090621B (Curran et al., GCN 9545) with the automated Palomar 60-inch telescope. Observations consisted of 20 x 180 s images in the i' filter at a mean epoch of 5:37 UT on 22 June 2009 (~ 7.5 hours after the burst).
  We detect the candidate afterglow reported by Levan et al. (GCN 9547) and Galeev et al. (GCN 9549) at low significance. Using several USNO-B sources in the field for reference, we measure a magnitude of I ~ 22.9. No other sources are detected inside the revised XRT error circle (Beardmore et al., GCN 9550).
  Directly comparing our P60 image with the WHT image from ~ 2 hours after the burst (GCN 9547), we find the candidate has faded marginally by 0.5 +- 0.3 mag. Further late-time observations will be needed to confirm if this is the optical afterglow of GRB090621B.
• GCN Circular #9559
  E. Berger (Harvard), A. Cucchiara, D.B. Fox (Penn State), and A.J. Levan (U. Warwick) report:
  "On 2009 June 22.41 UT we used the GMOS instrument mounted on the Gemini-North 8-m telescope to obtain spectroscopic observations of the candidate optical afterglow (GCN #9547) of the short GRB 090621B (GCN #9545). A pair of 1800 sec exposures were obtained with a wavelength coverage of 4500-7500A. The combined spectrum of the source reveals broad features typical of an early M dwarf star. We therefore conclude that this object is unrelated to the GRB."

  "Following the detection of the short-hard GRB 090621B by SWIFT (Curran et al. GCNC 9545) we carried out I-band observations with the 1.23m telescope at Observatory of Calar Alto. The observations were done on June 22.094-22.161 UT (4.14-5.75 hours post burst) with a total exposure time of 22x240s. The candidates reported by Levan et al. (GCNC 9547) and Galeev (GCNC 9549) are preliminarily detected at I~22.5 and I~20.6, respectively, against USNO-B field stars."

  A. Goldstein (UAH) and J.M. Burgess (UAH) report on behalf of the Fermi GBM Team:
  "At 22:07:25.70 UT on 21 June 2009, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 090621B (trigger 267314847 / 090621922) which was also detected by the Swift BAT (P.A. Curran et al. 2009, GCN 9545). The GBM on-ground location is consistent with the Swift position. The angle from the Fermi LAT boresight is 108 degrees.
  The GBM light curve consists of one short spike with a duration (T90) of about 0.128 s (8-1000 keV). The time-averaged spectrum from T0-0.064 s to T0+0.064 s is best fit by a Band function with Epeak = 321.60 +/- 129.00 keV, alpha = -0.13 +/- 0.38, and beta = -1.57 +/- 0.08 (chi squared 401 for 481 d.o.f.).
  The event fluence (8-1000 keV) in this time interval is (3.71 +/- 0.58)E-07 erg/cm^2. The 0.128-sec peak photon flux measured starting from T0-0.064 s in the 8-1000 keV band is 6.4 +/- 1.4 ph/s/cm^2.
  The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."

  We observed the field of GRB 090621B detected by Swift (trigger #355359; Curran et al., GCN #9545) with the 14-inch Goddard Robotic Telescope (GRT) located at the Goddard Geophysical and Astronomical Observatory (http://cddisa.gsfc.nasa.gov/ggao/).
  100 set of 30 sec exposures were taken in the R filter starting from June 22 01:51:44 (UT) about 3.7 hours after the trigger and stopped on June 22 02:47:51 (UT). We do not detect the optical afterglow both in the individual images and the combined image inside the XRT position (Beardmore et al., GCN #9550). The estimated three sigma upper limit of the combined image (total exposure of 2880 sec; excluding four bad quality images) is ~17.8 mag using the USNO-B1 catalog.

• GCN Circular #9656
  A. Pozanenko (IKI), A. Volnova (SAI MSU), V. Kouprianov, Ya. Naiden, V. Slesarenko, A. Devyatkin (Pulkovo Observatory), report on behalf of larger GRB follow-up collaboration:
  We observed the field of the Swift GRB 090621B (Curran et al, GCN 9545) with MTM-500 telescope of Kislovodsk solar station of the Pulkovo observatory in two series in R-filter between (UT) 2009-06-21 22:31 - 2009-06-22 00:01, i.e. starting ~24 minutes after burst onset. The upper limit of a stacked image of first 15 frames based on USNO B1.0 stars is following

  T0+         Filter   Exp.      mag.
  (mid, d)                 s
  0.02147  R        15x60  >18.5 (3 sigma)
  

  While we do not detect objects reported in GCN 9547 (Levan et al.) and GCN 9549 (Galeev et al.) in the stacked image above, we may suggest a possible object near the edge of the refined XRT error box (Beardmore et al., GCN 9550) in coordinates (J2000) RA = 20:53:53.24 Dec = +69:01:45.5. This possible object appears more intense in the stacked image of the first five frames, and does not appear in the second epoch of our observations started on Jun.21 (UT) 23:37. Due to low S/N ratio we cannot confirm the object is real. We encourage re-analysis of later deep observations to clarify the nature of the object.
  The finding chart can be found at http://grb.rssi.ru/GRB090621B/grb090621B_MTM.png , where source labeled #5 is the USNO B1.0 star 1590-0172172 (RA(J2000)=20:53:57.28, Dec(J2000)=+69:01:47.8, R2=19.41)

  The MAGIC Imaging Atmospheric Cherenkov Telescope performed a follow-up observation of the BAT short burst GRB090621B (Curran et al., GCN Circ. 9545). The burst was also triggered by Fermi-GBM (Goldstein et al., GCN Circ. 9562). We received the GCN alert at 22:07:38 UT (T0+13s). Data taking with MAGIC started at 22:43:33 UT (T0+2169s), when the GRB zenith angle went below 60 degrees. The observation continued for 12570 s.
  No evidence for VHE gamma-ray emission above the analysis threshold was found.
  A preliminary analysis, for the hypothesis of steady emission and assumption of a differential photon spectral index of -2.5, yields the following 95% CL differential flux upper limits, including a 30% systematic uncertainty on the telescope efficiency.
  Because of improving sensitivities and analysis threshold due to decreasing zenith angle during the observation, the data sample was split into 4 parts:

  E ( 300-1000 GeV): 0.42 * 10^-10 erg cm^-2 s^-1
  for a time window from 22:43:33 UT to 23:38:37 UT
  Analysis threshold: 407 GeV
  
  E ( 175- 300 GeV): 5.61 * 10^-10 erg cm^-2 s^-1
  E ( 300-1000 GeV): 0.19 * 10^-10 erg cm^-2 s^-1
  for a time window from 23:38:37 UT to 00:32:31 UT
  Analysis threshold: 291 GeV
  
  E ( 175- 300 GeV): 4.97 * 10^-10 erg cm^-2 s^-1
  E ( 300-1000 GeV): 0.24 * 10^-10 erg cm^-2 s^-1
  for a time window from 00:32:31 UT to 01:23:06 UT
  Analysis threshold: 224 GeV
  
  E ( 125- 175 GeV): 15.27 * 10^-10 erg cm^-2 s^-1
  E ( 175- 300 GeV):  1.25 * 10^-10 erg cm^-2 s^-1
  E ( 300-1000 GeV):  0.22 * 10^-10 erg cm^-2 s^-1
  for a time window from 01:23:06 UT to 02:13:04 UT
  Analysis threshold: 186 GeV
  

  We can also exclude emission of a constant flux in any 100s time bin smaller than:

  E ( 300-1000 GeV): 4.02 * 10^-10 erg cm^-2 s^-1
  for a time window from 22:43:33 UT to 23:38:37 UT
  Analysis threshold: 407 GeV
  
  E ( 175- 300 GeV): 23.60 * 10^-10 erg cm^-2 s^-1
  E ( 300-1000 GeV):  1.52 * 10^-10 erg cm^-2 s^-1
  for a time window from 23:38:37 UT to 00:32:31 UT
  Analysis threshold: 291 GeV
  
  E ( 175- 300 GeV): 15.33 * 10^-10 erg cm^-2 s^-1
  E ( 300-1000 GeV):  1.41 * 10^-10 erg cm^-2 s^-1
  for a time window from 00:32:31 UT to 01:23:06 UT
  Analysis threshold: 224 GeV
  
  E ( 125- 175 GeV): 22.23 * 10^-10 erg cm^-2 s^-1
  E ( 175- 300 GeV):  7.87 * 10^-10 erg cm^-2 s^-1
  E ( 300-1000 GeV):  1.15 * 10^-10 erg cm^-2 s^-1
  for a time window from 01:23:06 UT to 02:13:04 UT
  Analysis threshold: 186 GeV
