We have obtained SDSS g,r and i filter observations of SN 2023ixf in M101 discovered by K.Itagaki on 2023-05-19.728. the photometric observations 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.
Differential photometry was measured from secondary standard 2MASS J14040276+5418180 (LAMOST DR7 catalogs,Luo+ 2019) yielding the following (Sloan filter) values for UT 2023 May 20.407: g = 12.95 (0.01), r = 13.35 (0.01), i = 13.50 (0.01) and colours g -r = -0.39 and r -i = -0.16.
The differential photometry was performed using Image Reduction and Analysis Facility (IRAF) (Tody, D. 1986, "The IRAF Data Reduction and Analysis System").
We thank the Royal Astronomical Society of Canada (Victoria Centre) and Friends of Dominion Astrophysical Observatory for their kind donation of telescope time on their public outreach night for target of opportunity.
