Gabovich (Blagoveschensk Educational State University) MASTER-Kislovodsk robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the Fermi GRB240204.10 (trigger No 728706420,07h 55m 07.92s , +03d 07m 01.2s, R=29.57) errorbox 45762 sec after notice time and 45799 sec after trigger time at 2024-02-04 15:10:14 UT, with upper limit up to 14.2 mag. Observations started at twilight. The observations began at zenith distance = 73 deg. The sun altitude is -8.5 deg. MASTER-Tunka robotic telescope located in Russia (Applied Physics Institute, Irkutsk State University) started inspect of the Fermi GRB240204.10 errorbox 45869 sec after notice time and 45906 sec after trigger time at 2024-02-04 15:12:01 UT, with upper limit up to 20.8 mag. The observations began at zenith distance = 54 deg. The sun altitude is -46.9 deg. The galactic latitude b = 16 deg., longitude l = 218 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2370974 We obtain a following upper limits.
