GCN Circular 26970
R. Hamburg (UAH) reports on behalf of the Fermi-GBM Team: The newly discovered transient ZTF20aajnksq (GCN 26966) was found within the 3-sigma localization contour of GRB 200128A (GCN 26909) approximately 3 hours after the GBM trigger time. However the reported position of ZTF20aajnksq: 12:47:04.87 +45:12:02.3 (J2000) 191.770292 +45.200626 (J2000) was occulted by the Earth for Fermi-GBM from approximately 25.3 minutes prior until 1.8 minutes after the GRB trigger time. The position was also occulted 18.0 minutes prior until 8.8 minutes after the ZTF20aajnksq detection time. Therefore, we consider it unlikely that GRB 200128A is associated with ZTF20aajnksq.
