The SOHO spacecraft currently supplies daily images of the solar corona at 1.1-3, 2-6 and 4-30 solar radii. Are ground-based solar corona observations during total solar eclipses have becoming obsolete nowadays? A quick view of SOHO data shows that it is not perfect in some respects. ... On March 9, 1997 an expedition has been organized by the Russian Academy of Sciences to the Baikal region in Siberia for observation of the total solar eclipse. ... Fig. ...

Before you continue reading, you should know that this was not always the case, i.e. the Moon once was rotating with respect to the Earth, so that on every night a terrestrial observer (if there was one, because this was long, long before mankind appeared on our planet, and even before any major animals had appeared) saw another face of the Moon. ... Figure 1 (not to scale) shows how we can imagine the system Earth-Moon...

The period of this variable was first determined by Tony Vanmunster (Center of Backjard Astrophysics). We have taken the observations with CCD ST-7 and 60-cm reflector of SAI Crimean station. ... The longest set was taken at night of 2000 February 12 including 291 R 60 second long frames with the magnitude limit of 18. Summing all these frames in a single one I have taken a "deep sight" of this region having the limit of 21.7R. The effective exposition is 4 h. 51 m. Look at this frame! ...
