TITLE: GCN CIRCULAR NUMBER: 34098 SUBJECT: AT2023lcr: JCMT SCUBA-2 sub-mm observations DATE: 23/06/27 21:34:27 GMT FROM: Ian Smith at Rice U I.A. Smith (U. Hawaii), D.A. Perley (LJMU), and N.R. Tanvir (U. of Leicester) report: We have been observing the location of the transient AT2023lcr (Swain et al. GCN Circ. 34022; Fulton et al. GCN Circ. 34042) using the SCUBA-2 sub-millimeter continuum camera on the James Clerk Maxwell Telescope. No counterpart has been detected in the individual night or combined maps. Combining all the data, the RMS background noise was 1.7 mJy/beam at 850 microns and 30.1 mJy/beam at 450 microns; the mid-point of the run was at 2023-06-23.738 UT. We thank Andrea Waiters, Harold Pena, and the JCMT staff for the prompt support of these observations that were taken under project M23AP018.
