Gianluca Masi, Virtual Telescope Project (Italy), reports:
We observed the field of GRB 241030A (Klingler et al., GCN 37956; Beardmore et al., GCN 37962; Wang et al., GCN 37972; Pillera et al., GCN 37979; Ridnaia et al., GCN 37982; Ambrosi et al., GCN 37988; Wu et al., GCN 37997) with the 17”-432mm robotic unit available at the Virtual Telescope Project facility in Manciano, Italy, equipped with a KAF-6303E based CCD camera.
We collected 16, 300-second unfiltered exposures, then we averaged them. The central time of the resulting stack was 31 Oct. 2024, 18:27:50 UTC, that is about 36.8 hours after the burst.
We clearly detect the optical counterpart of GRB 241030A (Klingler et al., GCN 37956).
The position of the source is RA: 22 52 33.52; Decl.: +80 26 59.5 (J2000.0, mean residuals of 0.15”, reference stars from GaiaDR2) and the magnitude was estimated to be 19.9 (SNR=5, assuming R mags for the reference stars from GaiaDR2).
