Bersier, S. Kobayashi, M. Burgdorf, D. Carter (Liverpool JMU) report:

The 2-m Liverpool Telescope reacted robotically to GRB 080330 (Swift 
trigger 308041) starting 3 min after the GRB trigger time. We detect 
initially rising and subsequently fading optical candidate in r', i' and 
g' filters at the posotion consistent with XRT source, UVOT (Mao et al., 
GCN 7537) and TAROT optical candidate (Klotz, Boer & Atteia, GCN 7536).

The magnitude of the source in first frames is r'=17.3 +-0.1.
