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 GRB140824A (Beardmore et al. 16732) with the 1.5m
OSN telescope at Observatorio de Sierra Nevada (Spain). The observations
were carried out in the Clear band on Aug 24.84965-24.88029 (11.72-12.45
hours post bust). We do not detect any optical source brighter than R~21
consistent with the XRT position (Evans et al. 16735).
