Crain report: Skynet observed the field of GRB 120215A with the PROMPT telescopes located at CTIO in Chile. Observations in B, R, and I began at 00:42:24 UT, 69 seconds after the burst. While no source is detected in early images, stacks of later images do find an optical source of roughly 20th magnitude consistent with the XRT position reported by Hoversten et. al. (GCN 12954). mean-t #exp explen filt mag +(1sig) -(1sig) 19.27m 4 80s I 19.095 0.287 0.228 20.88m 6 80s B 20.320 0.361 0.274 Analysis is ongoing, although no further observations are planned as the field has set in Chile.
