GCN 10376,\nGoad et al GCN 10378) using the 2-m telescope of the IUCAA\nGirawali Observatory. Four 15-min exposures in R-band were\ntaken on 06 Feb 2010 starting at 15:46 UT.  The stacked\n1 hour exposure shows no optical transient to a limiting\nmagnitude of R ~22.  The extended source reported by Miller\net al (GCN 10377) is however clearly detected.",
