F. Espartero (IAA-CSIC), F.J. Aceituno (OSN/IAA-CSIC), J. Gorosabel
(IAA-CSIC/UPV-EHU) and A.J. Castro-Tirado (IAA-CSIC/UMA), report on behalf
of a larger collaboration:

We observed the field of the optical candidate reported for Fermi trigger
#430148973 (Lipunov et al. GCN 16720) with the 1.5m OSN telescope at
Observatorio de Sierra Nevada (Spain). The observations were carried out
in the I-band starting at 20:27:42 UT (6.6 hours post trigger). We do not
detect any source brighter than I=20.2 (Vega) consistent with the
candidate position.
