GCN Circular #5794
Brian Schmidt and Gordon Garradd (ANU) report on behalf of a larger collaboration
"We have observed the field of GRB061110A with the Uppsala Schmidt Telescope at Siding Spring Observatory. An Image taken at 11:59 UT shows no object at the XRT position brighter than R=19th magnitude."
GCN Circular #5795
A. D. Falcone (PSU), S. D. Barthelmy (GSFC), A. P. Beardmore (U Leicester), D. N. Burrows (PSU), S. Campana (INAF-OAB), M. M. Chester (PSU), J. R. Cummings (NASA/UMBC), P. A. Evans (U Leicester), N. Gehrels (NASA/GSFC), J. A. Kennea (PSU), V. Mangano (INAF-IASFPA), F. E. Marshall (NASA/GSFC), T. Mineo (INAF-IASFPA), C. Pagani (PSU), D. M. Palmer (LANL), M. Perri (ASDC), P. Romano (Univ. Bicocca & INAF-OAB), G. Sato (GSFC/ISAS) and L. Vetere (PSU) report on behalf of the Swift Team:
At 11:47:21 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 061110 (trigger=238108). Swift slewed immediately to the burst. The BAT on-board calculated location is RA,Dec 336.304, -2.267 {22h 25m 13s, -02d 16' 00"} (J2000) with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows multiple peaks with a duration of about 30 sec. The peak count rate was ~1000 counts/sec (15-350 keV), at ~5 sec after the trigger.
The XRT began observing the field at 11:48:30 UT, 69 seconds after the BAT trigger. XRT found a bright, fading, uncatalogued X-ray source on-board. The ground-calculated position, based on quick-look data products, is RA(J2000) = 22h 25m 10.0s, Dec(J2000) = -02d 15' 29.1", with an estimated uncertainty of 4.3 arcseconds (90% confidence radius). This location is 55.8 arcseconds from the BAT on-board position, within the BAT error circle. The initial flux in the 2.5s image was 5.2e-09 erg/cm2/s (0.2-10 keV).
UVOT took a finding chart exposure of 400 seconds with the V filter starting 71 seconds after the BAT trigger. No 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 3-sigma upper limit is 19.0 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 18.0 mag. No correction has been made for the expected extinction of about 0.3 magnitudes.
We note that there are at least 35 galaxies within 10 arcmin of the burst position.
GCN Circular #5796
B. E. Schaefer (Louisiana State), E.S. Rykoff (U Mich), F. Yuan (U Mich), W. Rujopakarn (U Arizona), report on behalf of the ROTSE collaboration:
ROTSE-IIIa, located at Siding Spring Observatory, Australia, responded to GRB 061110A (Swift trigger 238108), producing images beginning 8.8 s after the GCN notice time. An automated response took the first image at 11:48:04.9 UT, 43.6 s after the burst, under fair conditions. We took 10 5-sec, 10 20-sec and 10 60-sec eposures. These unfiltered images are calibrated relative to USNO A2.0 (R).
Comparison to the DSS (second epoch) reveals no new sources within the 3-sigma BAT error circle and also within the XRT error circle, for both single images and coadding into sets of 10; the field is not crowded. Individual images have limiting magnitudes ranging from 14.3-17.1; we set the following specific limits.

GCN Circular #5797
Y.C. Chen, Y.H. Lee, K.Y. Huang, W.H. Ip (NCU), Y. Urata (Saitama-U) on behalf of EAFON team report:
"We have performed optical observations using Lulin 1-m telescope for GRB 061110 from 51 min after the burst. We found a optical afterglow candidate of GRB 061110 located at RA = 22:25:09.8 Dec = -02:15:30 in our R and I band images. The source does not appear in DSS-II images. Our quick analysis indicates that the brightness of this source shows about 0.2 mag fading between 51 min and 85 min after the burst.
Further deeply observations are encouraged."

GCN Circular #5798
M.Zhai, L.P. Xing, Y.L. Qiu, J.Y. Wei, J.Y. Hu, J.S. Deng and W.K. Zheng, on behalf of EAFON report:
We have imaged the field of GRB 061110 with the TNT 0.8m telescope at Xinglong Observatory.The first image was taken at 11:48:37 UT, 76s after the burst. There is afaint uncatalogued source within XRT circle at position: Ra 22:25:09.8 Dec -02:15:30.7 J2000 This source has a mag ~19.5 in our combined White image at ~300s after the burst. This coordinate is consistent with the result given by Y.C. Chen et al.(GCN5797) and shows fading behavior, so the candidate is confirmed. Further analysis is under progress.

GCN Circular #5799
Christina C. Thoene, Daniele Malesani, Johan P. U. Fynbo (DARK Cosmology Centre), Christina Henriksen (DARK, NOT) and Dimitri Sharapov (NOT) report on behalf of a larger collaboration:
We observed the optical afterglow of GRB061110 (GCNs 5797, 5798) on Nov. 10 UT 19:35 (7.9h after the burst) with ALFOSC at the Nordic Optical Telescope on La Palma in the R and i bands.
We determined magnitudes of R=22.5 and i=21.6 using preliminary photometric zeropoints from the NOT webpages. Compared to the R-band magnitudes reported in GCNs 5797 and 5798, the afterglow has faded with a temporal decay index of beta~0.6.

Using the data set from T-240 to T+726 sec from recent telemetry downlinks, we report further analysis of BAT GRB 061110A (trigger #238108) (Falcone, et al., GCN Circ. 5795). The BAT ground-calculated position is RA,Dec = 336.284, -2.252 deg {22h 25m 8.1s, -2d 15' 6.0"} (J2000) +- 1.1 arcmin, (radius, sys+stat, 90% containment). The partial coding was 100%.
The mask-weighted lightcurve shows a FRED-like peak starting at ~T-15 sec, peaking at ~T+5 sec, and extending out to ~T+80 sec. T90 (15-350 keV) is 41 +- 2 sec (estimated error including systematics). The spectral lag is 2.75 sec +0.55-0.48 sec (between the 15-25 to 50-100 keV bands).
The time-averaged spectrum from T-8.8 to T+38.5 is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.67 +- 0.12. The fluence in the 15-150 keV band is 1.1 +- 0.1 x 10^-6 erg/cm2. The 1-sec peak photon flux measured from T+9.74 sec in the 15-150 keV band is 0.5 +- 0.1 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

L. Vetere, D. Morris, C. Pagani, J. Racusin, A. Falcone, D. N. Burrows (PSU) report on behalf of the Swift XRT team:
We have analysed the first 3 orbits of XRT data for GRB 061110A. A 560s photon counting mode image provides a refined XRT position:
```
RA(J2000)  =  22 25 09.9
Dec(J2000) =  -02 15 30.7
```
with an uncertainty of 3.7 arcsec (90% containment). This position is 2.2 arcsec away from the previous XRT position (Falcone et al. GCN 5795), 1.66 arcsec away from the optical afterglow detection by Chen et al. (GCN 5797) and 1.5 arcsec away from its later confirmation by Zhai et al. (GCN 5798).
The X-ray light curve in PC mode shows a rapid decay with a slope of -2.36 +/-0.22 in all the 1st orbit. While the 2nd and 3rd orbits show flattening. A power-law fit to the WT spectrum gives a photon index of 3.1 +/- 0.2 and a column density of (1.6 +/- 0.2)e21 cm^-2. We note that the galactic hydrogen column density in the direction of the burst is 4.94e20 cm^-2. The 0.2-10.0 keV observed mean flux during WT observation is 1.1-09 ergs cm^-2 s^-1, which corresponds to an unabsorbed flux of ergs 3.4e-09cm^-2 s^-1.
We are waiting for new data to make a prediction of the count rate. Note that the new event, GRB 061110B (GCN 5800), is 1hr away in RA and it is currently taking all the time from this observation.

Christina C. Thoene, Johan P.U. Fynbo (DARK-NBI), Pall Jakobsson (Univ. of Hertfordshire), Paul M. Vreeswijk (ESO) and Jens Hjorth (DARK-NBI) report on behalf of a larger collaboration:
We obtained a series of 3x1800s spectra of the OT of GRB 061110A (GCNs 5797, 5798, 5799) on November 11, 02:50UT (15h after the burst), using FORS1/VLT and grism 300V. At the time of the observations, the OT had a magnitude of about R=22 using photometric zeropoints from the ESO webpages.
Based on the detection of weak emission lines at 6551 AA and 8803 AA which we interpret as [OII] 3727 and [OIII] 5007 from the host galaxy, we determine a tentative redshift of z=0.757 for GRB 061110A. The continuum extends down to the blue end of the spectrum at 3600 AA which places an additional limit of z<2 on the redshift of this burst.
We thank the staff at VLT for performing the observations.

P. Schady (UCL-MSSL), A.D. Falcone (PSU) report on behalf of the Swift/UVOT team:
The Swift/UVOT began observing the field of GRB 061110a at 11:48:32 on 2006-11-10 UT, 71s after the BAT trigger (Falcone et al., GCN 5795). No new source was detected within the XRT error circle (Vetere et al., GCN 5806) or at the afterglow position reported by Zhai et al. (GCN 5798) in coadded images in any filter down to the following 3-sigma magnitude upper limits:
```
Filter  T_mid (s)    Exp. (s) 3-sigma UL
------------------------------------------------
V       3952            2579     20.42
B       4016            442      20.55

A. Falcone (Penn State) and N. Gehrels (GSFC) report on behalf of Swift Team:
On 2006 Nov 11 at 19:45:11 UT, Swift began target of opportunity observations of GRB 061110A to resume monitoring the afterglow during the weekend. Follow-up observations with other instruments are encouraged.

GCN Circular #5817
Christina C. Thoene and Johan P. U. Fynbo (DARK Cosmology Centre) report:
We further analysed our R-band data of the afterglow of GRB 061110A taken with ALFOSC/NOT (GCN 5799) and FORS1/VLT (GCN 5812). Crosscalibration of the two observation sets with a nearby star (RA=22:25:07.76, Dec=-02:15:00.52) and zeropoints from the ESO webpages gives revised magnitudes of R=23.3 at 8h after the burst (NOT) and R=23.9 at 14h (VLT), where we assume R=22.1 for the magnitude of the star. The offset to the magnitudes reported earlier are due to old ALFOSC zeropoints and refined reduction.
Together with the magnitude reported in GCN 5798, we find that a single powerlaw decay with a slope of alpha=0.83 +- 0.08 fits the data well. A plot of the lightcurve can be found at

GCN Circular #5818
Johan P. U. Fynbo (DARK) report:
Unfortunately I made an error in the gain-correction in the photometry reported in GCN #5817. Here are the correct numbers for the revised photometry. In the NOT images taken about 8 hr after the GRB) we measure R=22.5. In the VLT image taken about 14 hr after the GRB we measure R=23.1. Here we assume R=21.3 for the star at RA(2000) = 22:25:07.760, Dec(2000) = -02:15:00.52. I apologize for the confusion.
GCN Circular #6759
J.P.U. Fynbo, C.C. Thoene, D. Malesani, J. Hjorth, P.M. Vreeswijk (DARK), and P. Jakobsson (Univ. Hertfordshire) report on behalf of a larger collaboration:
We inspected in detail our VLT spectra (Thoene et al., GCN 5812) of the afterglow of GRB 061110A (Falcone et al., GCN 5795; Chen et al., GCN 5797).
Further to the lines reported in GCN 5812 (6552 and 8803 A), interpreted as [OII] and [OIII] 5007 at z=0.758, we also detect emission at 8547 A, which corresponds to Hbeta at the same redshift. We thus consider the redshift to be secure.
