Lowell Discovery Telescope Observations of ZTF21aayokph (AT2021lfa)
Abstract
We observed the field of ZTF21aayokph (AT2021lfa) reported by (Yao, Perley, & Ho, GCN Circ. 29938) using the Large Monolithic Imager (LMI) on the 4.3m Lowell Discovery Telescope (LDT) at Happy Jack, AZ. Observations started on May 6, 2021 at 05:39:57 UT (about 48 hours after the initial detection by ZTF) in the SDSS r-band. We detect the source with magnitude r ~ 21.63 +/- 0.02 AB mag. Compared to the magnitude determined by Butler et al. (GCN Circ. 29941) the transient faded with temporal index alpha ~ 1.5 in the r-band. Magnitudes are calibrated against the SDSS catalog and are not corrected for Galactic extinction. We thank the staff of the Lowell Discovery Telescope for assistance with these observations.
