MAXI GRB 230623A: MASTER optical observations

MASTER-OAFA obotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) pointed to MAXI/GSC GRB 230623A (Hagiwara et al. GCN 34068, Trigger=2023-06-23 07:23:37 UT, not came in socket, Tnotice(GCN)=09:39:20) at 2023-06-23 10:14:25UT through clouds with mlim=17.0 at first 6 images (sun alt.=-16 and sunrise), we don't find OT insode 0.23deg MAXI error-box by auto-detection system. We also made the difference with old MASTER image and didn't find new optical sources, that can be connected with GRB.
