follow-up photometry from the Dominion Astrophysical Observatory

A series of expoures were acquired of at2022sfe on UT 2022 Aug. 29.332 (9 x 60 sec) in the SDSS g' filter. The field is not in the Sloan footprint and as such we are using a Gaia Star at (J2000):

20 00 29.66 +34 53 38.0

of magnitude of G = 14.97 as a secondary standard. We find at2022sfe to be G = 19.72 +/- 0.04. Inspection of a PanSTARRS image stack shows two faint stars at the position of the transient separated by 5 seconds of arc. The northern star corresponds closely to the at position of the transient and has a published (Gaia) magnitude od 20.98
