TITLE: GCN CIRCULAR NUMBER: 36100 SUBJECT: GRB 240414A: MarSEC Observatory, Vicenza, Italy, UPPER LIMIT DATE: 24/04/14 21:27:52 GMT FROM: I. Peretto at MarSEC (Marana Space Explorer Center) <ricerca@marsec.org> Ivo Peretto (MarSEC, Marana Space Explorer Center, Marana Di Crespadoro, VI, Italy) Member of: UAI/SSV - Unione Astrofili Italiani/Sezione Stelle Variabili, GRB section. AAVSO (American Association Variable Stars Observers) In collaboration with: Stefano Lora and Giovanni Furlato (MarSEC, Marana Space Explorer Center, Marana di Crespadoro, VI, Italy) 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. ref.: GCN Circular 36083 Magnitudes were estimated with the APASS and are not corrected for galactic dust extinction.
