Scientific paper

The Solar-B Observatory is a highly capable satellite equipped with three advanced solar telescopes. Its solar optical telescope (SOT) has an unprecedented 0.2 arcsec resolution for observation of the solar atmosphere from space in multiple optical passbands. It will also, for the first time, measure the vector magnetic fields from space. The X-ray telescope (XRT) has broad temperature coverage and a spatial a resolution three times as high as Yohkoh. The image cadence will be significantly higher than Yohkoh's and a flare buffer will provide exceptional capability for observing rapid changes at flare onset. The EUV imaging spectrometer (EIS) has sensitivity ten times as high as the ESA SOHO instrument and covers a broad range of transition region and coronal temperatures. Flexible operating modes permit slit, slot and raster options in a selectable number of spectral lines. Both XRT and EIS have 2 arcsec spatial resolution (1 arcsec pixels). Solar-B is the follow-up mission to the very successful Japan/UK/US Yohkoh mission. We present a status report from the initial operation of the observatory, showing some of the first observations obtained. Following a short commissioning phase, science planning and regular operations are due to begin January 2007. All mission data will be open and freely available to researchers shortly after receipt at the DARTS data archive hosted in Japan.
