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.
