Abstract

We present photometric follow-up observations of the supernova candidate AT 2018we, which was discovered by the Gaia photometric alerts system. The first Gaia detection of the object was made Feb 12, 2018. Our observations, made in Cousins R and Johnson B band, range from Feb 20 to May 5, 2018. From our observations, we have constructed a light curve, which supports the initial prediction of type Ia, included in the Gaia alert. Based on this classification, we have also estimated the distance to its assumed host galaxy, which was found to be around 43 Mpc.
