A. Breeveld, GCN 34049) with the automatic 0.53m Ritchey-Chretien telescope + U47 detector at Montarrenti Observatory (Siena, Italy, IAU code C88).\n\nThe observations were started under mediocre weather conditions at 2023-06-19 21:54:09 UT (approximately 5 hours after notice) stacking a sets of R and I-band CCD images.\n\nThe OT was detected at the following position:\n\nRA      (J2000.0)  16h 31m 37.42s   +/-0.17 \nDecl. (J2000.0) +26° 21'   58.00\"   +/-0.16\n\nPreliminary photometry is obtained using nearby PanSTARRS stars as follows: \n\nMJD                   Filter   Mag.      Err.\n60114.91576     R       20.53   +/-0.20\n60114.91631      I       20.02   +/-0.19\n\nMeasures are not corrected for galactic dust extinction.\n\nMontarrenti Observatory (IAU code C88) is a public observatory located close to the homonym medieval castle near Siena - Italy managed by the local amateur astronomer association (Unione Astrofili Senesi). The main instrument is an automated and remoted  Ritchey-Chretien telescope D=0.53m - f/8.7 equipped with U47 back-illuminated camera. The observatory is devoted to supernovae search, GRB afterglow detection and photometric follow-up of blazars",
