  "body": "Heather F. Swan (U Mich), and Ian Smith (Rice), report on behalf of\nthe MARGE collaboration:\n\nThe AEOS Burst Camera (ABC), attached to the AEOS telescope, located at\nthe Maui Space Surveillance System on Haleakala, responded to GRB 050906\n(Swift trigger 153866), producing images between 10:47 and 10:59 UT,\nstarting 15 minutes after Swift-BAT triggered and located this burst.\nThese are 1s and 10s optical images were taken with a low resolution\ngrating.  With the revised BAT coordinates (GCN 3935), the ABC FoV\ncovers roughly 1/2 of the BAT error box, including IC 328.  Comparison of the 10\nsecond images (which start at 10:55 UT) to the DSS (second epoch) reveals \nno new sources to a limiting magnitude of 19. Further analysis of these\nimages is in progress.\n\n[GCN OPS NOTE(06sep05): Per author's request, the author-line was added; and\nthe FROM_line was changed from Flewelling to Swan.]"
