Next snapshots are acquired from lots of observatories and space probes. If you click on a chosen observatory, you will obtain more detailed picture of the sun. And if you click on the description of this picture, you connect with the page (in the chosen observatory), which deal with a given situation on the picture more detaily. By the way, you find out date and time of geting this picture, used filters and spectrum of offered services, which are available on this observatory.
It is a common project of European Space Agency (ESA) and National Aeronautics and Space Administration (NASA). A satellite, which is carrying lots of appliances, is destined for observing of the Sun and it was launched 2.12.1995. Weight of the satellite is 1850 kg and parametrs are 3,65 m x 3,65 m x 9,5 m. The control contact is maintained by Goddard Space Flihgt Center in Maryland, USA. An obtained data are used for a study of internal structure of the Sun, solar atmosphere and solar wind.

This satellite is dedicated to high-energy observations of the Sun, specifically of flares and other coronal disturbances. It is the japan project with participation of National Aeronatics and Space Administration (NASA). The Yohkoh mission was launched on August 30, 1991, from the Kagoshima Space Centre in southern Japan. The spacecraft is in a slightly eliptical, low-Earth orbit (approx. 570 x 730 km) with an orbital period of 96 minutes. The spacecraft carries a payload of four scientific instruments: the Soft X-ray Telescope(SXT), the Hard X-ray Telescope (HXT), the Bragg Crystal Spectrometer (BCS) and the Wide Band Spectrometer (WBS).
