A. Cucchiara (PSU), report on behalf of a larger collaboration:
"On March 5.42 UT we observed the field of GRB 100305A (Troja et
al., GCN 10470) with the Gemini-N telescope and the GMOS instrument.
In our 300s r'-band and 900s i'-band images we clearly detect
a source inside the XRT error circle at the following position:
RA (J2000) = 11:13:28.30
Dec (J2000) = 42:24:10.50
with an uncertainty of 0.5" in each coordinate.
Using 2 USNO-B1 stars we calibrated our photometry and obtained
r' = 23.95 +- 0.30 mag
i' = 23.71 +- 0.50 mag
At the moment no evidence of fading can be addressed.
Further analysis are in progress.
We thank the Gemini staff for performing this observation,
in particular Andrew Stephens."
