GRB200829A: optical afterglow detection from Konkoly Observatory J. Vinko, K. Vida, A. Pal, L. Kriskovics, R. Szakats, A. Ordasi and K. Sarneczky (Konkoly Observatory, Hungary) report: The optical afterglow of GRB 200829A (Siegel et al. GCN 28307) is detected with the 0.8m RC80 robotic telescope at Piszkesteto Station of Konkoly Observatory starting on Aug 29 19:22:00 UT, 19346 s after the Swift/BAT trigger. The afterglow is measured on stacked Sloan r'- and i'-band frames of 3x300 s exposure. Photometry, tied to nearby comparison stars with PS1 magnitudes, gives. r' = 18.45 +/- 0.09 and i' = 18.49 +/- 0.11 mag, in accord with previous optical detections (Pozanenko et al. GCN 28308; Kuin et al. GCN 28311; Ursi et al. GCN 28314; Lipunov et al. GCN 28315)..
