Akerlof (U Mich), and M.\nSkinner (Boeing) report on behalf of the MARGE collaboration:\n\nThe AEOS Burst Camera (ABC) on the AEOS telescope, located at the Maui \nSpace Surveillance System on Haleakala, observed the field of GRB071011 \n(Swift trigger 293924 (F. E. Marshall et al, GCN 6882)). The images are \nunfiltered 10s exposures which started ~6 minutes after the trigger and \nended ~ 1 hour later.  We see the OT candidate observed by Perley et al \n(GCN 6883), but it does not fade (between 6-60 minutes).\n\nThe first image which contains the XRT position (B. Sbarufatti et al, \nGCN 6891) occurred at 20 minutes after the Swift trigger.  We coadded \nthe ABC images into sets of 10 and observe three distinct closely spaced \nstellar objects within 7 arc-seconds of the XRT coordinates given in GCN \n6891. These appear to be consistent with a set of unresolved stars in \nthe DSS plates (second epoch) suggesting that no new sources have been \nfound within the 3-sigma XRT error circle.",
