"We have observed the field of GRB070412 (Romano et al. GCNC
6273) with the IAC80 telescope at Observatorio del Teide in I
filter, starting at 03:02 UT, i.e. 1.6 h after the trigger. 

Inspection of a 30 minute combined image shows a faint
(4-sigma) source at 

	12:06:10.416,+40:08:24.12 +-0.5" (J2000)
with the I-band brightness 21.5+-0.5. The object is not
consistent with the candidate of Malesani et al. (GCN 6276).
The identification map is at

Further observations are needed to confirm the transient
nature of this object.
