Summary:

T Pyx is a short orbital period recurrent nova with previous outbursts in 1890, 1902, 1920, 1944, 1966, and now 2011. The outburst in 2011 was discovered and reported to have a visual magnitude of 13.0 on 2011 April 14.29. White light observations of T Pyx, using The Solar Mass Ejection Imager (SMEI) were made from 2011 April 15.70 UT (t = 1.4 days) to 2011 May 20.90 UT (t = 36.6 days). These photometric observations provide unprecedented detail regarding the behavior of the light curves and are compared to the spectra of T Pyx obtained by FRODOSpec on the Liverpool Telescope plus those obtained by the SMARTS telescopes. The investigations of how spectra change together with brightness are presented in order to determine the origin of light curve variability in the early stage of the nova outburst.
