GRB 100708: 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 100708 detected by XXX
(trigger XXX) with the TAROT robotic telescope (D=25cm)
located at the Calern observatory, France.

The observations started 212146613017.0s after the GRB trigger
(XXXs after the notice). The elevation of the field increased from
8 degrees above horizon and weather conditions
were XXX.

---- NO
The date of trigger : t0 = 1858-11-17T00:00:00.000

The first image is trailed with a duration of 180.0s
(see the description in Klotz et al., 2006, A&A 451, L39).
We do not detect any OT with a limiting magnitude of:
t0+212146613017.0s to t0+212146613197.0s : R > 15.1

The second image is 180.0s exposure in tracking mode:
t0+212146613214.7s to t0+212146613394.7s : R > 16.2

We co-added a series of exposures:
t0+212146613214.7s to t0+212146614599.4s : R > 17.7
---- YES
We detect a new fading source in the error box given by XXX
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 212146613017.0s 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=189.5622 lat=-11.7528
and the galactic extinction in R band is 0.4 magnitudes
estimated from D. Schlegel et al. 1998ApJ...500..525S.
