A. Crain report:
Skynet observed the field of GRB 111107A, Swift trigger 507185, with the
PROMPT telescopes located at CTIO in Chile. We detect a fading optical
source within the error circle. Preliminary calibration to USNO catalog
stars yields the follow initial detections:
Tmean(min) Tmean(day) Tel Exp Filt Mag S/N
14.75 m 0.01024 Prompt4 5 x 80 s R 19.467 2.892
15.22 m 0.01057 Prompt5 4 x 80 s I 18.444 4.363
Further observations are ongoing. This message may be cited.
