Skynet observed the Swift-BAT localization of GRB 140215A (Markwardt et al., GCN 15837, Swift trigger 586680) with six of the PROMPT telescopes located at CTIO in Chile.  Observations began at ~59s after the burst in BVRI and luminance. We detect a fading optical source in all bands at the position of the source detected by Markwardt et al.

A preliminary light curve calibrated to USNOB and NOMAD catalog stars can be found at:

Further observations are ongoing.
