July 22, 2009 - The X-ray Solar Eclipse |
The Russian TESIS (FIAN) Solar Observatory has transmitted observations back to Earth of the solar eclipse made on July 22nd, 2009.
Thanks to the specific orbit of the space vehicle, the observatory's x-ray telescopes detected the eclipse twice. On the first occasion, the satellite passed through the eclipse area at 04:30 Moscow time, making it the first on our planet to see the shadow of the Moon, which was still in space and was only approaching the Earth (film 1.2 MB, wmv format). And 4 hours later, when almost all the inhabitants of the Earth had already said goodbye to the eclipse, TESIS telescopes captured images of the second deepest transit of the Moon across the Sun (film 1.2 MB, wmv format).

July 20, 2009 - The TESIS Observatory will observe two solar eclipses from space |
Early in the morning on 22 July, 2009, at around 01.00 GMT (05.00 Moscow time) the trajectories of the Sun and Moon will converge at a particular point in the celestial sphere, and on Earth the Moon's shadow will fall on India. This will mark the beginning of one of the most beautiful phenomena in the natural world and astronomy - a full solar eclipse, which, this year, will move from Asia across India, China, Japan, the Marshall and Gilbert Islands, and will finish its journey on the Pacific Ocean at around nine in the morning Moscow time (05.00 GMT). This year's eclipse is unique in duration. At its climax, the Earth will be plunged into darkness for 6 minutes and 39 seconds. However, this long period of darkness will only be observed by sailors out at sea and a few lucky yacht owners - the point of maximum eclipse (northern latitude 21њ12.6', eastern longitude 144њ06.4') will be on the Pacific Ocean close to the edge of the Philippine Sea. India's inhabitants will be able to feast their eyes on the fiery-edged black disk of the Sun for around three and a half minutes, and China, across which the Moon's shadow passes, will be plunged into darkness for 4.5 to 6 minutes.

July 6, 2009 - TESIS has photographed this year's most powerful solar flare |
This year's most powerful solar flare was photographed by TESIS telescopes in the southern hemisphere of the Sun on July 5th, 2009. The flash lasted 11 minutes from 10:07 until 10:18 Moscow time, reaching its peak at 10:13 Moscow time. At its highest point, the intensity of solar X-rays reached level С2.7 on the 5-point GOES scale.
Fortunately, a further increase in the Sun's activity coincided with the beginning of the shadowless orbits of the CORONAS-PHOTON satellite, onboard which the observatory works. The space vehicle's orbit plane will be turned to the Sun at an angle of approximately 90 degrees within the next two weeks. As a result, the vehicle will not enter the Earth's shadow while it is rotating in orbit and will be able to observe the Sun uninterruptedly. This means that almost all of the solar events of these days will be captured by the TESIS telescopes. Three foreign space vehicles (the Japanese HINODE satellite and two NASA STEREO vehicles) will switch over to high observation frequency mode together at the beginning of the TESIS shadowless orbits.
