GRB 240824B: KAIT optical upper limit

The 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at Lick Observatory, responded to GRB 240824B (Fermi GBM team, GCN 37260; Nakajima et al., GCN 37261; DeLaunay et al., GCN 37267; Sharma et al., GCN 37284) starting at 06:53 UT, Aug. 25, ~17.70 hours after the burst. A total of 180 x 60s images were obtained in the clear (roughly R) filters. We did not detect any new optical counterpart candidate within the Swift/XRT X-ray afterglow (Source 1) error circle reported by Kennea et al. (GCN 37270) in our coadd image, which we estimate the limiting magnitude to be ~21.0 mag at a mid time of 20.70 hours after the burst, consistent with the upper limit report from Malesani et al. (GCN 37281).
