GCN #33176)\nwith the SAO RAS 1-m telescope Zeiss-1000 + CCD-photometer in Rc band.\n\nInside the XRT error circle we detected new transient object\nreported by Zhu et al. (GCN #33177) and Nazarov et al. (GCN #33178)\nwith the coordinates\nR.A. = 06:34:28.2\nDec. = +49:52:20.5 (+/- 0\".3, J2000) and brightness\nR = 19.93 +/- 0.07 (T - T0 = 0.9378h),\nR = 19.72 +/- 0.06 (T - T0 = 1.4236h)\nPreliminary photometry is based on R2 magnitudes of nearby USNO-B1 stars.\n\nFurther observations are ongoing and encouraged.",
