Abstract:
We have obtained SDSS u, g and r filter observations of specific optical transients discovered by ZTF (Fremling, C., et al.), Pan-STARRS (Chambers, K.C., et al.), ATLAS (Tonry, J., et al), A. Horti-David, et al and K.Itagaki. 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 standards are as follows; 2MASS 14040276+5418180, 2MASS J23270681+4135467, SDSS  J164845.48+413436.5, SDSS  J160953.21+153528.9, SDSS  J164733.01+521940.5, 2MASS J18415625+4956224, SDSS  J172844.13+582236.9 and 2MASS 00433834+4115321.
 
 
 Several different secondary standards were used from SDSS DR16 (Ahumada+, 2020), LAMOST DR7 catalogs (Luo+, 2019), All-sky spectrally matched Tycho2 stars (Pickles+, 2010) and PS1 Survey DR1 (Chambers+, 2016) to perform differential photometry using Image Reduction and Analysis Facility (IRAF) (Tody, D. 1986, "The IRAF Data Reduction and Analysis System").
