Gehrels (GSFC)\n\nWe report the independent detection of early afterglow (or post prompt- \nemission flaring) emission from the short GRB 080123 (GCN#7203). The  \nBATSS pipeline processed the BAT data from the initial automatic slew  \nto the burst, which started at 04:22:09 UT (T+12sec), and was  \ncompleted within 5 hours of the BAT trigger. A 6.2-sigma image\ndetection (from stacked 0.2sec slew images throughout the 68sec slew)  \nin the 15-50 keV energy band yielded a position of:\n  RA(J2000) = 22h 35m 08s\n  Dec(J2000) = -64d 57' 24\"\nwith an uncertainty of 6 arcmin (90% confidence radius), consistent  \nwith the XRT reported position of GRB080123 (GCN# 7208). Preliminary  \nlightcurve analysis shows the BATSS image detection is due to an  \ninital ~4sec duration flare at T+20, followed by two possible broader  \n(~10-15sec) peaks at T+49 and T+72. The total estimated fluence is  \n2.1E-7 erg/cm2  (15-50keV; derived for a PL model with photon index 2)  \nover the 68.8sec duration of the slew. This fluence is a factor of  \n0.36 times that reported in the 15-150keV band (GCN Report 111.1) for T \n+0.3 to T+122.2 and is likely dominated by the soft flare emission  \nafter the prompt hard emission of the short GRB.\n\nBATSS pipeline processing is in the final stages of development  \nfollowing our first preliminary tests, which discovered GRB070326  \n(GCN# 6653). Full BATSS results will begin to be available soon from a  \nwebsite\nto be announced.",
