Spectral energy distribution of the host galaxy of AT 2019avd compiled from archival GALEX, SDSS, UKIDSS, and ALLWISE photometry, with the best-fit model shown as a red solid line. The three epochs of Swift UVOT photometry where all filters were used are also plotted. AT 2019avd shows a ~ 1 mag rise in the UVW1, UVM2, and UVW1 bands relative to the best fit model to the archival photometry.
