report on behalf of the Swift/XRT Team:
At 13:25:13.4 UT on December 12, 2014, 85.2 seconds after the BAT trigger,
XRT began observing GRB 141212B. We find a uncatalogued source at an XRT
count rate of 2-3 c/s during the first orbit, and 0.4 c/s during the 2nd
orbit observations. Based on 140s of PC mode data, we find a preliminary
localization of RA/Dec(J2000) = 250.87573, 31.752983, equivalent to:
RA(J2000) = 16h 43m 30.1s
Dec(J2000) = 31d 45m 10.7s
with an estimated uncertainty of 10 arc-seconds radius (90% confidence).
We expect this position to be improved as we collect more data.
