Abstract
We report Swift XRT observations of the supersoft X-ray transient (XMMU J005510.7-373855) in NGC 300 (Kong & Di Stefano 2003). The source was first detected as a supersoft X-ray source (kT ~ 50 eV) in 1992 with ROSAT and disappeared in subsequent X-ray observations. The source was active again in 2000 December and 2001 January and was detected with XMM-Newton with luminosities of 1e38 - 1e39 erg/s.
