Gabovich (Blagoveschensk Educational State University) MASTER-Tavrida robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, SAI Crimea astronomical station) was pointed to the Swift GRB 240414A ( R. Caputo et al., GCN 36083) errorbox 53869 sec after notice time and 53925 sec after trigger time at 2024-04-14 17:19:21 UT, with upper limit up to 17.3 mag. Observations started at twilight. The observations began at zenith distance = 32 deg. The sun altitude is -10.0 deg. The galactic latitude b = 60 deg., longitude l = 131 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2422039 We obtain a following upper limits.
