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).

Analysis is ongoing, although no further observations are planned as the
field has set in Chile.
