Abstract
We report a Chandra observation of the supersoft X-ray transient (XMMU J005510.7-373855) recently in outburst in NGC 300 (Kong & Di Stefano 200; ATel #1560). A 10ks DDT observation was taken on 2008 July 8 UT with ACIS-S in Very Faint mode. The supersoft X-ray transient was clearly detected with all photons from below 0.7 keV. The energy spectrum is well fitted with an absorbed blackbody model with N_H=(4.3+/-1)e20 cm^-2 and kT=61+/-6 eV (90% confidence).
