Detection of two new soft X-ray sources and their identification with the supernova remnants (RNRs) 3C400.2 and MSH 15-56, is reported. From the observed X-ray flux in the 0.7-2.0 keV energy range, the X-ray luminosity of 3C400.2 is derived to be in the range of (2.7-5.3)×1035 ergs s−1 and that of MSH 15-56 in the range of (0.9-1.6)×1035 ergs s−1. If we use the standard adiabatic shockwave model for the SNR's, an age of ∼ (1.4-3.2)×104 yr is derived for 3C400.2 whereas MSH 15-56 is found to be younger of an age of (5-10)×103 yr.
