TITLE: GCN CIRCULAR NUMBER: 38032 SUBJECT: GRB 241030A: further SAO RAS optical observations DATE: 24/11/01 11:48:47 GMT FROM: Moskvitin Alexander at SAO RAS <mosk@sao.ru> A. S. Moskvitin (SAO RAS) and V. P. Goranskij (SAI MSU) report on behalf of the GRB follow-up team. We observed the field of GRB 241030A / EP241030a (Klingler et al., GCN 37956; Beardmore et al., GCN 37962; Wang et al., GCN 37972; Pillera et al., GCN 37979; Ridnaia et al., GCN 37982; Ambrosi et al., GCN 37988; Wu et al., GCN 37997; Liang et al., GCN 38026) with the 1-m telescope of SAO RAS, Zeiss-1000 equipped with the CCD-photometer on October 31, 17:49:28--18:22:41 UT (t_mid - T0 = 1.5125 days = 36.3 hours). The OT (Klingler et al., GCN 37956; Watson et al., GCN 37957; Fernández-Rodríguez et al., GCN 37958; Zheng et al., GCN 37959; An et al., GCN 37960; Higuchi et al., GCN 37963; Qiu et al., GCN 37965; Lin et al., GCN 37966; Wu et al., GCN 37970; Breeveld & Klingler, GCN 37974; Méndez-Lapido et al., GCN 37993; Moskvitin & Goranskij, GCN 38016; Busmann et al., GCN 38019; Schneider et al., GCN 38021; Li et al., GCN 38027; Masi, GCN 38031) is clearly detected in our 3 x 600 sec stacked frame in Rc band with the brightness of R = 20.31 +/- 0.06 (R_lim = 22.6), calibrated against nearby Pan-STARRS stars (magnitudes converted with Lupton 2005 equations) and not corrected by MW extinction.
