Skynet observed the field of GRB 110928A (Hoverston et al., GCN 12394) 
with the GLAST Optical Robotic Telescope (GORT) at the Hume observatory 
in California beginning roughly 75 minutes after the burst.   We do not 
detect any uncatalogued sources.  Stacking only images that increase the 
limiting magnitude yields:
