UVOT Image of M33
A Swift UVOT UV mosaic of 13 observations (red: uvw1, green: uvm2, blue: uvw2) of M33. The 13 individual pointings (with 1 ks exposure time per UVOT UV filter) cover the entire disk of the galaxy. The resulting image is one of the best ultraviolet observations of any galaxy obtained to date.
