Observations of the 2010 January Outburst of the Recurrent Nova U Scoprius using NASA's Swift

We report on X-ray observations of the recurrent nova U Scorpius (U Sco) obtained with NASA's Swift during the 2010 Jan outburst. X-ray spectra were obtained in the 0.1-10 keV band at least once per day throughout the outburst which commenced on 2010 Jan 28 and lasted $\sim$70 days. We fit the spectra with an absorbed, low-order continuum component; the fits yield an integrated X-ray luminosity, the interstellar absorption column, and a pseudo-temperature derived from the continuum parameter. We describe the overall evolution of the X-ray flux as well as the absorption and temperature across the burst.
