GRB 091202: TAROT Calern observatory optical observations
Klotz A. (CESR-OMP), Gendre B. (IASF),
Boer M. (OHP-OAMP), Atteia J.L. (LATT-OMP) report:

We imaged the field of GRB 091202 detected by INTEGRAL
(trigger 5957) with the TAROT robotic telescope (D=25cm)
located at the Calern observatory, France.

The observations started 18.2s after the GRB trigger
(XXXs after the notice). The elevation of the field increased from
45 degrees above horizon and weather conditions
were XXX.

---- NO
The date of trigger : t0 = 2009-12-02T23:10:28.814

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+18.2s to t0+78.2s : R > 15.1

The second image is 30.0s exposure in tracking mode:
t0+97.2s to t0+127.2s : R > 16.2

We co-added a series of exposures:
t0+97.2s to t0+320.2s : R > 17.7
---- YES
We detect a new fading source in the error box given by INTEGRAL
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 18.2s 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=152.2007 lat=+40.1968
