... 96.1655Garwood+ We presented results from a continuum VLA snapshot survey of the galactic plane in the longitude range 0d < l < 90d at 1.5 GHz. Observations were taken every 0.5^o in longitude at b=0^o. Most fields are complete to about 30 mJy peak density. The positions, peak, and total flux density of 471 compact sources (<30") have been measured. ...

Since the 1980s VLBI observations at two frequencies, 8.4 (X-band) and 2.3 GHz (S-band) have been used to locate the positions of compact radio sources with unprecedented accuracy. ... Observations of selected strong compact extragalactic radio sources, using this now mature technique, have been used to define and maintain a radio reference frame with sub-milli-arcsecond (mas) precision. ... Additionally, it will provide more reference sources for phase referencing VLBI observations. ... References . ...

... There is no question about the source of ionospheric plasma , since it is created from the ambient neutral atmosphere by ionization. However, the source of magnetospheric plasma is a much more complicated question: although it seems obvious that both solar wind and ionosphere feed it, the relative importance of these two sources is unclear. ... Protons (H + ) are the primary ions in solar wind and one of the major components in ionospheric outflows, and thus not good indicators of their source. ...
