Malesani (DARK/NBI), S.\nCovino (INAF-OAB) report for a larger collaboration:\n\n\"We obtained a third epoch of observations of the localization of\nGRB 100316D (Stamatikos et al. GCN 10496; Starling et al. GCN\n10519) using Gemini South and GMOS. Observations began at 23:48 UT\non March 18, and were obtained in the r-band under excellent\nseeing (0.5\"). Image subtraction reveals that the source previously\nidentified by Levan et al (GCN 10523), has brightened between the two\nobservations by ~0.3 magnitudes.  We suggest that this object\nrepresents the rising supernova associated with GRB 100316D.\n\nImages of the field, and the subtraction can be found at\n\nhttp://www.star.le.ac.uk/~anl/100316D\n\nFurther observations are planned.\n\nWe thank the staff of Gemini for their help in executing these\nobservations\"",
