On April 8, 2005, an optical afterglow of the GRB 050408 was discovered with the SAO's telescopes (the 1-meter telescope Zeiss and 6-meter telescope BTA) within the framework of a joint BTA request (SAO RAS + IAA CSIC, Granada, Spain) on optical identification of gamma-ray bursts. We first detected a variable object only by our own data in the localization error-box reported by the space observatory HETE and then it was confirmed by our observations in SAO. ...

... These trajectories have an initial flight from the Earth to a large distance (of about 1.5 million km), the following passive flight to the Moon's orbit, an approach to the Moon with a decrease of an energy of a particle (spacecraft) selenocentric motion to a negative value and the temporary capture in an elliptic orbit of the Moon's satellite. ...

... Following a flare on 9 July '96, a solar quake on the solar surface was observed for the first time. It contained 40,000 times the energy released in the great earthquake that devastated San Francisco in 1906. In an hour, the waves traveled a distance ten times that of the Earth's diameter. The waves accelerated from 22,000 miles per hour to 250,000 miles per hour as they travelled outwards and disappeared into the photosphere. A solar-quake following a large flare . ...
