 The "superhumps" see the star increase by 0.24 magnitude for 1.55 hours during these superoutbursts.Spectroscopic observations of the white dwarf with the Hubble Space Telescope and Space Telescope Imaging Spectrograph reveal it to be spinning at a speed of 200 km/s, with a surface temperature of 18800 K and is estimated to have 0.6 the mass of our sun.Up to 75% of the brightness of the object comes from the accretion disc, which is heated to a temperature of 6500 K.
