We have re-analyzed the full XRT data set of GRB 061210. XRT observed the field of GRB 061210 for a total exposure time of 73 ks between December 12 and December 20, 2006 in Photon Counting mode....Full Text

We have obtained a spectrum of the possible host galaxy S2-G2 (Berger, GCN 5922) of the short-hard GRB 061210 (Cannizzo et al., GCN 5904). S2-G2 is an r=21 galaxy with a bulge-dominated morphology on the outskirts of the possible XRT afterglow S2 (Godet et al., GCN 5921). Using the Low-Resolution Imaging Spectrometer mounted on the 10-m Keck I telescope, we obtained 2 x 30 min spectra of...Full Text

"Following our initial observation of the entire Swift BAT error circle (GCN 5906), we continued observing the XRT candidates of short GRB 061210 (Godet et al., GCN 5921) using V, R and I filters on the MDM 1.3m telescope on Dec. 12-13 UT. In a summed 60-minute exposure centered at Dec. 13 09:03 UT, we clearly detect the extended galaxy candidate "S2-G2" reported by Berger (GCN 5922) at...Full Text

The Swift/UVOT observed the field of GRB 061210 starting 2.42 days after the BAT trigger (Cannizzo et al., GCN 5904). No afterglow optical candidate is detected in either of the XRT error circles in 18.5 ks of exposure time from T+2.42 days to T+3.48 days in U band. We clearly detect the extended source near the candidate S1 (Berger et al., GCN 5922) at the following coordinates: ...Full Text

"Inspection of our Gemini/GMOS images (GCN 5912) at the positions of XRT sources S1 and S2 (GCN 5921) reveal the presence of several extended optical sources, one of which may be the host galaxy of GRB 061210....Full Text

We analysed 26ks of XRT data for the short burst GRB 061210 (Cannizzo et al., GCN 5904) taken between 2.42 days and 2.72 days after the BAT trigger. Swift observed this burst late due to a Moon constraint. The XRT/PC image shows two sources S1 and S2 in the BAT error circle located at: ...Full Text

"The 2-m Faulkes North Telescope robotically followed up the Swift GRB 061210 (trigger #243690, Cannizzo et al) and began observing about 2.4 minutes after the GRB trigger time....Full Text

"The short GRB 061210 (Cannizzo et al. GCN 5904, Palmer et al GCN 5905) triggered the Suzaku Wideband All-sky Monitor (WAM), which covers the energy range of 50 keV - 5 MeV, at 12:20:39 UT December 10, 2006. The duration T90 was about 0.047 second. The fluence in 100-1000 keV of the burst was about 2.02(-0.33, +0.35)x10-6 erg/cm2 . Preliminary result shows that the time-averaged spectrum is well...Full Text

We observed the field of the short-hard GRB 061210 (Cannizzo et al., GCN 5904) with the Gemini Multi-Object Spectrograph in imaging mode mounted on the Gemini North telescope. Our first set of observations was taken in r' at a mean epoch of 14:27 Dec. 10 UT (2.1 hours after the burst) and covers ~ 90% of the refined BAT error circle (Palmer et al., GCN 5905). Contamination from the nearby...Full Text

"We used the Very Large Array to observe the field of view toward GRB 061210 (GCN 5904) at a frequency of 8.46 GHz on 2006 December 12 at 9.81 UT. The peak radio brightness at the BAT ground-calculated position (GCN 5905) is 26 uJy ± 34 uJy. The nearest source in the GRB field of view is at a distance of 3.54 arcmin, cataloged in NVSS and FIRST survey as J093751+153629....Full Text

1 Introduction

BAT triggered on a short hard burst, grb(061210}, at 12:20:39 UT (Trigger 243690) (Cannizzo, et al. GCN 5904, Palmer, et al., GCN 5095). Swift did not slew because of the Moon observing constraint -- this burst is 4 deg from the Moon. The BAT on-board calculated location is RA, DEC (J2000) = (144.514, +15.632) deg which is (09h 38m 03s, +15d 37' 56"), with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows a hard, single spike structure with a duration of ~0.2 sec and a soft extended emission for ~90 sec.

No XRT or UVOT observations will be possible until the burst emerges from the spacecraft Moon constraint at about the start of 12-12-2006.

"We observed the entire Swift BAT error circle of short GRB 061210 (Cannizzo et al., GCN 5904; Palmer et al., GCN 5905) in the I band on the MDM 1.3m telescope. Combined exposures obtained in the interval 39-66 minutes after the burst show no new object to a limiting magnitude of I~18.5 in comparison with the USNO-B1.0 catalog, despite high background from the nearby bright moon....Full Text
