GCN Circular 4568
H. Swan (U Mich), C. Akerlof (U Mich), E. Rykoff (U Mich), S. Yost (U Mich) and I. Smith (Rice), report on behalf of the MARGE collaboration: The AEOS Burst Camera (ABC) on the AEOS telescope, located at the Maui Space Surveillance System on Haleakala, observed the fading counterpart to GRB 060116 (Swift trigger 177533 (GCN 4519)). Images were taken between 08:45:11 UT (7.7 minutes after it was detected by Swift) and 09:09:38 UT. These are unfiltered optical images. The diffraction grating normally mounted on the ABC was temporarily removed to accommodate observations of the final approach of the NASA Stardust mission. After a comparison of our images with the USNO B 1.0 R2 catalog, we see a fading optical transient centered within 0.06" of the OT reported by Kocevski (GCN 4528). A preliminary analysis gives an R-equivalent magnitude of approximately 20.0+/-0.1 at 08:45:29 UT. Further analysis is in progress.
