Ward Moody report for Brigham Young\nUniverisity�s ROVOR team:\n\nWe observed the field around GRB 090429A (Swift trigger 350853,\nMarkwardt et al., GCN 9280) with the ROVOR (Robotic Observatory for\nVariable Object Research) 16� telescope from Delta, Utah. Beginning 30\nApril 2009 at 03:46:50 UT (22.3 hours after outburst), observations\nwere obtained for a complete integration time of 50 minutes in white\nlight. No detection was made after stacking the images. Using the\nmagnitude limits established by Olivares et al., GCN Circ. 9303 on the\n2.2m ESO/MPI telescope at La Silla Observatory, we estimate a\nmagnitude limit of 22 � 1 mag on these observations.",
