Speckhard, A.Trotter, and J. A. Crain report:
Skynet observed the field of GRB120328A (Pagani et al., GCN 13147, Swift
trigger #518792) with the PROMPT telescopes located at CTIO in Chile
beginning 4.1 minutes after the burst. We do not detect any uncatalogued
sources in our earliest images (mean time 4.43 minutes after the burst)
down to 3-sigma limiting magnitudes of V=17.92, R=18.73, I=18.15.
Stacking all data taken up to 17.2 minutes after the burst yields 3-sigma
limiting magnitudes of B=19.19, V=19.75, R=20.26, I=19.38. Limits were
calibrated to nearby USNO-B1.0 stars for B,R,I, and nearby NOMAD stars for
V.
