GRB __TN-N: TAROT Calern observatory optical observations
Klotz A. (CESR-OMP), Gendre B. (LAM-OAMP),
Boer M. (OHP-OAMP), Atteia J.L. (LATT-OMP) report:
We imaged the field of GRB __TN-N detected by XXX
(trigger XXX) with the TAROT robotic telescope (D=25cm)
located at the Calern observatory, France.
The observations started 212125594931.0s after the GRB trigger
(XXXs after the notice). The elevation of the field decreased from
69 degrees above horizon and weather conditions
The date of trigger : t0 = 1858-11-17T00:00:00.000
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+212125594931.0s to t0+212125594991.0s : R > 15.1
The second image is 60.0s exposure in tracking mode:
t0+212125595011.0s to t0+212125595071.0s : R > 16.2
We co-added a series of exposures:
t0+212125595011.0s to t0+212125595071.0s : R > 17.7
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 212125594931.0s 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=115.2081 lat= -0.6139
