Abstract
I imaged the field of GRB 230414B detected by SWIFT(trigger 1164180) with the telescope of Nastro Verde Observatory-Sorrento (Naples), Italy. Member of: AAVSO - American Association of Variable Star Observers. UAI/SSV - Unione Astrofili Italiani/sezione stelle variabili. AstroCampania Associazione The observations started at 20:28 UT of 2023/04/14 with principal telescope SC 0.35 f/10 with focal reduced + CCD Sbig ST10 XME I took 12 image of 180 sec each. All images are unfiltered stacked with Tycho Tracker software . Start T0+ End T0+ 20:28:53 UT 21;26:21 UT I detected a (fading) afterglow in the error box of the XRTcandidate. A. D'Ai (INAF-IASFPA), E. Ambrosi (INAF-IASFPA), et al. at the following position (+/- 2 arcsec): RA (J2000.0) = 12h 04m 22.73s DEC(J2000.0) = +53° 09' 15.3" The results of our photometry are: ----------------------------------------- Date UT CR-mag Middle +/- 0.05 ----------------------------------------- 2460049.354 19.760887 2460049.359 19.691675 2460049.361 19.481389 2460049.363 19.618392 2460049.365 19.760087 2460049.367 19.909645 2460049.37 19.739394 2460049.374 19.071181 2460049.388 19.378857 2460049.394 21.82892 ----------------------------------------- Magnitudes were estimated with the Gaia DR2 cat. and are not corrected for galactic dust extinction.
