Abstract:
Photometric Follow up Observations of specific transients.

We have obtained SDSS filter observations of AT 2023igp, AT2023ins, AT2023hrq and AT2023ipx using 1.8-m Plaskett Telescope (E2V, 4K x 2K CCD) at the (Dominion Astrophysical Observatory) of the National Research Council of Canada.

 

We find the following magnitude and colour by performing differential photometry.
