TITLE: GCN CIRCULAR NUMBER: 33239 SUBJECT: ZTF23aabmzlp/AT2023azs: Mondy and AbAO optical observations DATE: 23/01/31 15:17:33 GMT FROM: Alexei Pozanenko at IKI, Moscow N. Pankov (HSE), A. Pozanenko (IKI), E. Klunko (ISTP), R. Ya. Inasaridze (AbAO), and S. Belkin (IKI) report on behalf of GRB IKI FuN: We observed the optical transient of ZZTF23aabmzlp/AT2023azs (Andreoni et al., GCN 33229) with AZT-33IK telescope of Mondy observatory starting on 2023-01-29 (UT) 21:25:32 and AS-32 Abastumani observatory (AbAO) on 2023-01-30 (UT) 17:04:08. We detect the transient (Andreoni et al., GCN 33229; Kumar et al., GCN 33230; Gupta et al., GCN 33237) with AZT-33IK and obtained an upper limit with AS-32.
