Gabovich (Blagoveschensk Educational State University) MASTER-SAAO robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in South Africa (South African Astronomical Observatory) was pointed to the Integral GRB240115.70 (trigger No 10472,12h 47m 16.10s , -35d 33m 29.1s, R=0.053) errorbox 12776 sec after notice time and 12801 sec after trigger time at 2024-01-15 20:19:16 UT, with upper limit up to 18.9 mag. The observations began at zenith distance = 87 deg. The sun altitude is -26.0 deg. The galactic latitude b = 27 deg., longitude l = 303 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2356567 We obtain a following upper limits.
