GCN Circular 33241
R. Strausbaugh (University of Minnesota), A. Cucchiara (NASA) report on behalf of a larger collaboration: We observed the ZTF23aabmzlp/AT2023azs (Andreoni et al., GCN 33229) field with the LCOGT 1-meter Sinistro instrument at the McDonald Observatory, TX, USA site, on January 29, from 09:46 to 10:02 UT (corresponding to 27.53 to 27.80 hours after ZTF first detection) with the SDSS r filter. We performed a series of 3x300s exposures in r band. We marginally (2-sigma) detect a source at the candidate coordinates with evidence for continued fading from previous optical observations (Kumar et al., GCN 33230; Gupta et al., GCN 33237; Pankov et al., GCN 33239). The following magnitude is calculated using the PanSTARRS catalog as reference: r = 22.07 +/- 0.13 These magnitudes are not corrected for galactic extinction.
