GCN 36555)  of Swift GRB240529A (Eyles-Ferris et al. GCN36556, Ttrigger= 02:58:31UT)\nin MASTER-SAAO at 3 degrees altitude at 2024-05-29 02:59:20 by wide-field MASTER-II camera and\nat 2024-05-29 02:59:16 (44s after GRB time) by very wide field MASTER-VWF camera.\n\nThe optical transient MASTER OT J222126.06+513344.6 clearly detected since\n03:00:20 with m_OT~14.5 at first maximum and with possible second maximum  at light curve\nduring prompt emission of this GRB (Swift-BAT lightcurve Markwardt,Barthelmy et al. GCN36566)\n\nThe reduction of first 40 images from MASTER-VWFC since 2024-05-29 02:59:16  with OT substraction will be continued.\n\nObservations started at zenith distance = 87 deg. The sun  altitude was  -31.0deg.\nThe galactic latitude b = -5 deg., longitude l = 101 deg.\n\nReal time updated cover map and OT discovered available here:\nhttps://master.sai.msu.ru/site/master2/observ.php?id=2474976\n\n",
