... We have been using it to analyze PC images of known gravitational lenses and QSOs which are candidates for lensing (Falco 1993). ... Fig. 1 plots the higher contours of the PC image of 0142 in the upper left, and its power spectrum in the upper right. ... If we fit the envelope of the power spectrum with a binary model, we find that best fit gives a separation of the two components of 1.3 PC pixels or about 58 mas. ... The lower two curves are cuts through the 0142 power spectrum. ...

... The storm began quite unexpectedly. The strongest geomagnetic storm for the last seven months began on Earth almost precisely at the same time as the solar eclipse reached its maximal stage, the culmination of which occurred at GMT 02:35 (06:35 Moscow time). ... Oscillations of such amplitude in the magnetic field have not been observed since October, 11th of last year, which is more than seven months ago. ... We can only add that the magnetic storm lasted approximately 9 hours. ...

... The most spectacular view however is from space, where large areas of aurora can be observed simultaneously, even the entire polar cap. ... Such pictures often show a continuous ring of aurora around the polar cap (picture above), caused mostly by electrons leaking out along magnetic field lines, from the plasma sheet of the Earth's magnetic tail. ... Field lines from the auroral oval are believed to lead to the plasma sheet. ... A near-Earth circular polar orbit has many uses. ...

... In particular, members of the project regularly organize events dedicated to various interesting astronomical phenomena and events - solar and lunar eclipses, transit of Venus, etc. On November 3rd a team of astronomers will venture deep into Turkana National Park, Kenya and attempt to broadcast the magic of a total solar eclipse to the world. ...
