TITLE: GCN CIRCULAR NUMBER: 27118 SUBJECT: LIGO/Virgo S200213t: APO Upper Limits for ZTF20aanakes/AT2020cly DATE: 20/02/18 05:56:04 GMT FROM: Eric C Bellm at UW Eric C. Bellm (UW) and Melissa Graham (UW) report on behalf of the GROWTH collaboration: On 2020-02-15 02:23 we imaged the location of ZTF20aanakes/AT2020cly (Coughlin et al, GCN #27095), a transient located inside the error region of S200213t (LVC,GCN #27042), using the Astrophysical Research Consortium Telescope Imaging Camera (ARCTIC) on the Apache Point Observatory 3.5m. We obtained 120-second exposures in g, r, and i bands. We do not detect the transient in any band; we estimate two-sigma detection limits of m_g ~ 23.5 mag, m_r ~ 23.0 mag, and m_i ~ 21.5 mag. We thank the APO staff for their support of this Target of Opportunity observation.
