Skynet observed the Swift-BAT localization of GRB 140301A (Page et al., 
GCN 15896, Swift trigger 589590) with the 14-inch R-COP telescope at 
Perth Observatory, Australia.  Observations began at 93s and continued 
until 33m post-trigger, with rotating exposures in the BVRI bands 
increasing from 10s to 80s. We detect no optical source in stacked 
images in any band at the position of the source detected by the Swift 
XRT. Preliminary upper limits are:
Band      tmid      mag
V         17m       >18.5
R         22m       >19.0
I         18m       >18.0

Photometry is calibrated to seven APASS-DR7 stars in the field, and has 
not been corrected for the Galactic foreground extinction corresponding 
to E(B-V)=0.03 (Schlegel et al. 1998).

No further Skynet observations are scheduled.
