... After 1958, when scientific satellites began exploring the Earth magnetic environment, many puzzling phenomena could be directly examined, especially the polar aurora and disturbances of the Earth's magnetic field [see Stern , 1989a]. ... The large-scale structure of the magnetosphere, the space region dominated by the Earth's magnetic field, was gradually revealed within the next decade: its trapped particles, its boundary, and its long magnetic tail on the night side. ...

Next: The Plan Up: No Title Previous: No Title . On the afternoon of 19 October 1999, it was discovered by John Briggs that the secondary mirror in the 2.5m SDSS telescope had developed a series of circular cracks around its axis of symmetry. As the telescope had not been in use since the early morning of 16 October 1999, there was a great deal of concern and consternation as to what caused these fractures in the glass. ... 11/24/1999 ...

. The Guest FTP Service at the University of London Computer Centre provides a gateway service between InterNet file transfer protocol (FTP), and the file transfer mechanism used over JANET (Blue Book NIFTP). Suppose you can only transfer files between your local host and other remote hosts on JANET using the hhcp command. This service enables you to transfer files to and from hosts on the InterNet through its gateway.

... Structure of Data . ... Catalog . ... In SAI OCL Catalog, we introduce our work on investigation of the Milky Way system of open star clusters. The main goal of our study is a search for new clusters using huge surveys. 168 new clusters have been already discovered by us using J,H,Ks data from 2MASS point source catalog. ... For 141 new clusters, we found their physical parameters using J,H,Ks data from 2MASS catalog and, for a number of clusters, our UBVRI CCD observational magnitudes. ...
