GRB 111016: TAROT Calern observatory optical observations
----------------------------------------------------------------------
Klotz A. (CESR-OMP), Gendre B. (ASDC),
Boer M. (OHP-OAMP), Atteia J.L. (LATT-OMP) report:

We imaged the field of GRB 111016 detected by SWIFT
(trigger 505516) with the TAROT robotic telescope (D=25cm)
located at the Calern observatory, France.

The observations started 174701.2s after the GRB trigger
(174620.8s after the notice). The elevation of the field increased from
15 degrees above horizon and weather conditions
were XXX.

---- NO
The date of trigger : t0 = 2011-10-15T01:12:40.608

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+174701.2s to t0+174881.2s : R > 15.1

The second image is 180.0s exposure in tracking mode:
t0+174891.0s to t0+175071.0s : R > 16.2

We co-added a series of exposures:
t0+174891.0s to t0+176079.4s : 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 174701.2s 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=203.1415 lat=+55.4419
and the galactic extinction in R band is 0.1 magnitudes
estimated from D. Schlegel et al. 1998ApJ...500..525S.
