Foley (UC  \nBerkeley) report:\n\n\"We obtained simultaneous J, H, and Ks band images with fine time  \nsampling (7.8s cadence) of the afterglow (Rykoff et al. 6987; Covino  \net al. 6988) of GRB 070125A (Pagani et al. 6986) with PAIRITEL (*)  \nbeginning ~200s after the BAT trigger.   The beginning of the  \nobservations coincides with the fading tale of the prompt emission.   \nThe IR light curve initially rises, then exhibits two prominent peaks  \n(at T+~500s and T+~1500s) before fading as a powerlaw t^{-1.5+/-0.1},  \nafter t ~ 2000s.  A refined data reduction and a search for potential  \ncolor variations are in progress.\"\n\nThis message may be cited.\n\n(*) http://pairitel.org\n\n\n*****************************************************\nJoshua Bloom\nAssistant Professor, UC Berkeley\n601 Campbell Hall, Berkeley, CA 94720\n(510) 643-3839 [Office]  447 Campbell\n(510) 643-4621 [Lab]      260 Evans\nhttp://astro.berkeley.edu/~jbloom\n*****************************************************",
