... 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. ...

The Sun is our nearest star and the source of energy for life on Earth. ... For centuries astronomers wondered whether they were clouds floating in the Sun's atmosphere, but we now know that they really are huge regions of magnetic field, about as intense as the field at the poles of an iron magnet. ... Such abrupt events were named solar flares , and what made them especially interesting was that occasionally, after a prominent flare, a magnetic storm would erupt on Earth. ...

Space Radio Telescope . The space radio telescope antenna consists of a deployable parabolic reflector (10-m diameter) which is made of 27 carbon fiber petals and central solid portion (3 m in diameter). The radio telescope has focus to diameter ratio F/D=0.43 and overall RMS surface accuracy 0.7 mm. ... A concentric feed arrangement at prime focus will provide the possibility of observing at two frequencies or two circular polarizations simultaneously. ... Observing frequency (MHz) . ...

Possible values are 'CLEAN' , if the mirrors have been re-coated or cleaned within two weeks of the observing run, and/or a flashlight beam is barely visible on optical surfaces; 'AVERAGE' , if a flashlight beam is plainly visible on the optical surface, but the dirt is not very bad; and 'DIRTY' , if shining a flashlight beam on the primary produces a sensation of revulsion in a trained observer. ...
