D. A. Perley and C. M. Copperwheat (LJMU) report:
We acquired a short sequence (40 seconds each in g/r/i filters) of
imaging at the locations of all five of the marginal ATLAS transients
reported by McBrien et al. (GCN 24197) using IO:O on the 2m Liverpool
Telescope. We do not detect a significant source at the location of
any of these transients. Approximate 3-sigma upper limits (AB,
calculated relative to SDSS or PS1 secondary standards) are:
