A. S. Moskvitin, V. N. Komarova, V. V. Sokolov and T. N. Sokolova
(SAO RAS GRB follow-up team) report:
The field of GRB 111022B (Holland et al., GCN#12472) was observed
with the 6-m BTA/Scorpio on October, 23, 2011. We obtained 3 x 180 sec.
frames in the Rc band and 25 x 120 sec. in the Ic band.
Observations in Rc began at 00:40:10 (7.5 hours after the trigger),
ended at 00:50:21 UT; in Ic began at 01:23:11 UT (8.2 hours after the
trigger), ended at 02:22:40 UT. Conditions were clear with a seeing
of about 1".2 (FWHM of stellar objects in the Ic co-added image).
The possible optical counterpart is clearly detected in the Ic band
within the 1".5 XRT error circle (according to
http://www.swift.ac.uk/xrt_positions/) at the coordinates:
R.A. (J2000) = 07:15:51.56
Decl. (J2000) = +49:41:01.7
with the uncertainty 0".2.
The object magnitude is I = 23.6 +/- 0.3 as compared to USNO-B1.0 Imag
of six nearby stars. The high error is due to calibration, the 3-sigma
limit of the Ic co-added image is about 24.7. We do not detect the object
in the Rc-band down to the 3-sigma level limiting magnitude of about 24.3.
The Ic image can be found at
ftp://ftp.sao.ru/pub/grb/GRB111022B/GRB111022B_BTA.jpg
Our results are in agreement with the previously reported NOT observations
(Vreeswijk et al., GCN#12479) and do not contradict the idea of a high
redshift burst according to Gemini infrared observations (Levan et al.,
GCN#12481).

Using the data set from T-239 to T+963 sec from the recent telemetry
downlink,
we report further analysis of BAT GRB 111022B (trigger #506074)
(Holland, et al., GCN Circ. 12472). The BAT ground-calculated position is
RA, Dec = 108.927, 49.663 deg which is
RA(J2000) = 07h 15m 42.4s
Dec(J2000) = +49d 39' 45.9"
with an uncertainty of 2.0 arcmin, (radius, sys+stat, 90% containment).
The partial coding was 82%.
The mask-weighted light curve shows a multi-peak structure starting at
~T-50 sec and ending at ~T+60 sec. T90 (15-350 keV) is 79.1 +/- 13.5
sec (estimated error including systematics).
The time-averaged spectrum from T-47.84 to T+53.80 sec is best fit by a
simple
power-law model. The power law index of the time-averaged spectrum is
1.59 +/- 0.20. The fluence in the 15-150 keV band is 9.0 +/- 1.2 x 10^-07
erg/cm2.
The 1-sec peak photon flux measured from T+49.54 sec in the 15-150 keV band
is 0.4 +/- 0.3 ph/cm2/sec. All the quoted errors are at the 90% confidence
level.

V. D'Elia, G. Stratta (ASDC), S. T. Holland (CRESST/USRA/GSFC) report
on behalf of the Swift-XRT team:
We have analysed 8.5 ks of XRT data for GRB 111022B (Holland et al.
GCN Circ. 12472), from 127 s to 18.5 ks after the BAT trigger. The
data comprise 134 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 12478).
The light curve can be modelled with a series of power-law decays. The
initial decay index is alpha=1.7 (+/-0.9). At T+176 s the decay
steepens to an alpha of 3.64 (+0.26, -0.22) before breaking again at
T+404 s to a final decay with index alpha=2.05 (+0.26, -0.21).
A spectrum formed from the WT mode data can be fitted with an absorbed
power-law with a photon spectral index of 2.41 (+0.14, -0.13). The
best-fitting absorption column is 1.46 (+0.27, -0.26) x 10^21 cm^-2,
in excess of the Galactic value of 7.3 x 10^20 cm^-2 (Kalberla et al.
2005). The PC mode spectrum has a photon index of 1.59 (+0.15, -0.12)
and a best-fitting absorption column consistent with the Galactic
value. The counts to observed (unabsorbed) 0.3-10 keV flux conversion
factor deduced from this spectrum is 4.5 x 10^-11 (5.0 x 10^-11) erg
cm^-2 count^-1.
A summary of the PC-mode spectrum is thus:
Total column: 0 (+2.7, -0) x 10^20 cm^-2
Galactic foreground: 7.3 x 10^20 cm^-2
Excess significance: <1.6 sigma
Photon index: 1.59 (+0.15, -0.12)

"We observed the localization of GRB 111022B (Holland et al. GCN

Observations were obtained in poor conditions (2.5" seeing) and
began 17 hours after the burst in the YJHK filters.
We find a single source within the refined XRT error circle (Beardmore
et al. GCN 12478). The source is well detected in both H and K,
with K~19.0 +/- 0.2, but only very weakly in J. Given the earlier
non-detections in the optical (Vreeswijk et al. GCN 12479) the
inferred optical-IR colour is red (R-K > 4.2), coupled with the
lack of apparent excess N_H this could be indicative of a high
redshift burst.
Analysis is ongoing, and further observations are planned."

RA, Dec 108.951, +49.666 which is
RA(J2000) = 07h 15m 48s
Dec(J2000) = +49d 39' 59"
with an uncertainty of 3 arcmin (radius, 90% containment, including
systematic uncertainty). The BAT light curve shows nothing which is typical
for an image trigger.
The XRT began observing the field at 17:15:21.8 UT, 137.3 seconds after
the BAT trigger. Using promptly downlinked data we find a bright,
fading, uncatalogued X-ray source with an enhanced position: RA, Dec
108.9646, 49.6835 which is equivalent to:
RA(J2000) = 07h 15m 51.49s
Dec(J2000) = +49d 41' 00.4"
with an uncertainty of 2.5 arcseconds (radius, 90% containment). This
location is 69 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 consistent with the Galactic value of 7.32
x 10^20 cm^-2 (Kalberla et al. 2005).
The initial flux in the 2.5 s image was 8.17e-10 erg cm^-2 s^-1 (0.2-10
keV).
UVOT took a finding chart exposure of 150 seconds with the White filter
starting 144 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
0.07.
