The 2-m Faulkes Telescope North robotically followed up GRB070521
(Guidorzi et al., GCN 6431, trigger=279935) beginning ~2.5 minutes
after the GRB trigger time (UT:06:51:10).
No new object has been detected inside the XRT error circle (Guidorzi
et al., GCN 6431) down to a limiting magnitude of R~19.3 (texp = 30
sec) and I~18.5 (texp = 10 sec), at a mean epoch of ~3 and ~6 minutes
after the burst, respectively (comparison with respect to the USNO B1
catalog).
Further observations are ongoing.
