Prague, August 16, 2006 . Our trial revision of the GCVS data for several southern constellations show that type changes are not needed for most stars. ... We suggest to add one more symbol combining types, in the cases when two or more classification options remain for the same star, for example, EC|Ell, EC|RR (here EC means a contact eclipsing binary, this is one of our suggestions from next slides). ... Moreover, it will simplify moving stars from the suspected-variable catalogue to the GCVS. ...

... Moon Phase below . ... ARTICLE: Why the moon always shows us the same face . ... 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...
