Skynet observed the Swift-BAT localization of GRB 140213A (Holland et
al., GCN 15825, Swift trigger 586569) with the 14-inch R-COP telescope
at Perth Observatory, Australia. Observations began at 59s and
continued until 92m post-trigger, with rotating exposures in the BVRI
bands increasing from 10s to 80s. We detect a fading optical source in
all bands at the position of the source detected by the Swift UVOT
(Siegel & Holland, GCN 15826). The source faded from R=14.3 at t=113s to
R=17.8 at t=73m.
A preliminary light curve is at:
Photometry is calibrated to five APASS-DR7 stars in the field, and has
not been corrected for the Galactic foreground extinction corresponding
to E(B-V)=0.07 (Schlegel et al. 1998).
Skynet observations are ongoing.
