Warwick), N.R. Tanvir (U. Leicester), D. Malesani (DARK/NBI), S.
Covino (INAF-OAB) report for a larger collaboration:
"We obtained a third epoch of observations of the localization of
GRB 100316D (Stamatikos et al. GCN 10496; Starling et al. GCN
10519) using Gemini South and GMOS. Observations began at 23:48 UT
on March 18, and were obtained in the r-band under excellent
seeing (0.5"). Image subtraction reveals that the source previously
identified by Levan et al (GCN 10523), has brightened between the two
observations by ~0.3 magnitudes. We suggest that this object
represents the rising supernova associated with GRB 100316D.
Images of the field, and the subtraction can be found at

Further observations are planned.
We thank the staff of Gemini for their help in executing these
observations"
