GRB 111228: TAROT Calern observatory optical observations
----------------------------------------------------------------------
Klotz A. (IRAP-OMP), Gendre B. (ASDC/INAF-OAR),
Boer M. (OCA-CNRS), Atteia J.L. (IRAP-OMP) report:

We imaged the field of GRB 111228 detected by SWIFT
(trigger 510649) with the TAROT robotic telescope (D=25cm)
located at the Calern observatory, France.

The observations started 15281.9s after the GRB trigger
(15233.4s after the notice). The elevation of the field increased from
1 degrees above horizon and weather conditions
were XXX.

---- NO
The date of trigger : t0 = 2011-12-28T15:44:43.583

The first image is trailed with a duration of 60.0s
(see the description in Klotz et al., 2006, A&A 451, L39).
We do not detect any OT with a limiting magnitude of:
t0+15281.9s to t0+15341.9s : R > 15.1

The second image is 30.0s exposure in tracking mode:
t0+15352.8s to t0+15382.8s : R > 16.2

We co-added a series of exposures:
t0+15352.8s to t0+15848.2s : R > 17.7
---- YES
We detect a new fading source in the error box given by SWIFT
We detected the candidate couterpart mentioned by XXX et al. (GCNC XXXX)
at the following position (+/- 3 arcsec):

RA(J2000.0) = XXh XXm XX.XXs
DEC(J2000.0) +XXd XX' XX.X"

OT was R~XX.X at 15281.9s after GRB.
----

Magnitudes were estimated with the nearby USNO-B1 stars
and are not corrected for galactic dust extinction.

N.B. Galactic coordinates are lon=216.3410 lat=+49.7585
and the galactic extinction in R band is 0.1 magnitudes
estimated from D. Schlegel et al. 1998ApJ...500..525S.
