... This year's eclipse is unique in duration. ... Although, at the present time, there are 6 solar observatories belonging to leading space agencies in orbit around the Earth, the eclipse of 22 July, 2009, will only be seen by two of them: the Russian CORONAS-PHOTON satellite equipped with TESIS telescopes and Japan's HINODE satellite fitted with an XRT space telescope. ... TESIS will be the first of the two devices (and the very first on Earth) to witness the solar eclipse. ...

Comment on J0513-2159 . Our image shows an extension to about 5 mas SE from the brightest feature. The EVN 8 GHz image by Dallacasa et al. (1998), with about five times larger resolution, shows an extension from the brightest feature roughly opposite to our direction. As noted by Dallacasa et al. (1998), the structure detected has a highly inverted spectrum, which, together with the reported variability in the source, could explain the structural disagreement. ...
