Crain report:\n\nSkynet observed the field of GRB 120119A with the PROMPT telescopes located \nat CTIO in Chile. Observations in B, R, and I began at 04:05:08 UT, 38 \nseconds after the burst. We detect an optical source consistent with the \nUVOT position reported by Beardmore et. al. (GCN 12859) in all three \nfilters. �The optical afterglow faded for the first ~2.3 minutes, then \nbrightened until approximately minute 14, after which it resumed fading. \nThe afterglow is red, with (I - R) ~ 1 mag and (R - B) ~ 2 mag. �\n\nA preliminary light curve can be found at:\nhttp://skynet.unc.edu/grb/grb120119a.png\n\nFurther observations are ongoing.",
