Abstract
The Solid State Camera (SSC) on board MAXI/ISS is working properly since the launch on July, 2009. It consists of 32 CCDs each of which is an X-ray CCD with one inch square. The effective energy range is from 0.7keV to 12keV. Since MAXI passes through high background regions at high latitude due to its inclination angle of 51deg, we notice a degradation of the CCD performance as we expected.
MAXI has accumulated the data that reveal various activities including nova, GRBs, flare stars, pulsars, etc. These will be reported in detail by the Gas Slit Camera (GSC). We will concentrate on the results of a soft energy range below 2keV which cannot be observed by the GSC. There are many extended structures in the soft energy range. The Cygnus Loop and the Vela SNR are bright extended sources near the galactic plane. The Cygnus Super Bubble and the Loop I are also seen by the SSC. The effective energy range of the SSC is above 0.6-0.7 keV, depending on the background condition. Therefore, the X-ray map obtained is similar energy range to that the medium energy range of the ROSAT All Sky Survey (RASS). We will report the latest results and the comparison of the RASS.
