Taylor and J. A. Crain report
Skynet observed the Swift XRT localization of the field of GRB 130612A
(Racusin et al., GCN 14874, Swift trigger #557976), beginning at
2013-06-12, 3:23:27 UT (t=70s post-trigger) using three 16" telescopes
of the PROMPT array at Cerro Tololo, Chile. We detect a fading
afterglow in the B, V and I bands at a position (J2000.0)
consistent with the detections of Racusin et al. (GCN 14874), Melandri,
Mundell & Gomboc (GCN 14875), and Morgan (GCN 14876).
A preliminary light curve is at:
Preliminary photometry is calibrated to 5 NOMAD/USNO B1.0 stars in the
field, and magnitudes are in the Vega system.
Skynet observations are ongoing.
