Abstract:
We have obtained SDSS u, g and r filter observations of SN 2023ixf in M101 discovered by K.Itagaki on 2023-05-19.728. The photometric observations and colour index were done using 1.8-m Plaskett Telescope (E2V, 4K x 2K CCD) at the (Dominion Astrophysical Observatory) of the National Research Council of Canada.

* secondary standard 2MASS J14040276+5418180

The secondary standard was used from LAMOST DR7 catalogs (Luo+, 2019) and All-sky spectrally matched Tycho2 stars (Pickles+, 2010).

The differential photometry was performed using Image Reduction and Analysis Facility (IRAF) (Tody, D. 1986, "The IRAF Data Reduction and Analysis System").
