report:
We imaged the field of GRB 240414A detected by SWIFT(trigger=1221714)
with the telescope  14” RC Officine Stellari of MarSEC (Marana Space Explorer Center).

The observations with a series of 120 sec exposures started at 2024-01-01 18:18 UT, 958 min. after the GRB trigger, with a Ritchey-Chretien telescope D=360 mm f/ 8.

at the following position:

RA(J2000) = 12h 19m 09s
Dec(J2000) = +56d 43' 37"


Weather conditions were medium with Moon illuminated 40,5%.

We co-added 30 exposures of 120 sec each.

Start T0+      End T0+       R lim.
 958 min       1018 min       20.82

We did not found any optical counterpart in A.R. 12 19 09, DEC. +56 43 37 position and in the error box of the XRT candidate.
