GRB 200906A: EMIR/GTC NIR upper limit
Abstract
We observed the field of GRB 200906A (Page et al., GCN #28371; GBM detection: Fermi GBM Team, GCN #28370; Hamburg et al., GCN #28374) with EMIR on the 10.4m GTC telescope, at the Roque de los Muchachos Observatory (La Palma, Spain). The observation consisted of H-band imaging with a total integration time of 955 s, and a mean epoch on the 6th of September at 23:57:35 UT (10.5753 hr after the Swift trigger). No source is detected within the refined XRT error circle (Beardmore et al., GCN #28373) down to a 3-sigma limit of H(AB) > 23.5 mag This non detection is consistent with the previously reported limits (Fu et al., GCN#28372; Kann et al., GCN#28376; Kumar et al., GCN#28377; Gropp et al., GCN#28379; Rossi et al. GCN#28381) and confirms the dark nature of the burst.
