follow-up photometry from the Dominion Astrophysical Observatory

SDSS filter observations of the SN candidate at2023hcp on

UT 2023 Apr. 30.44

using the 1.82-m Plaskett telescope (Dominion Astrophysical Observatory) of the National Research Council of Canada. Using star SDSS J164837.22+355710.6 as a secondary standard in the field

we find the following magnitude and colour:

g (SDSS) = 17.49 +/- 0.02

u (SDSS) = 17.66 +/- 0.04
