... The Scientist's Expert Assistant (SEA) is a prototype effort for the Next Generation Space Telescope that uses a combination of artificial intelligence and user interface techniques to explore ways to substantially reduce the time and effort involved in proposal preparation for both scientists and the telescope operations staff. ... At the time, SEA supported only a single observation, had the basics of a graphical exposure calculator and a visual target tuner, and had a very limited expert system. ...

Inverted TRACE images at 195 illustrating development of the EUV post-eruption arcade with the well-organized loop, two-ribbon, and spine structures. Note that the exposures have been rescaled to the same peak intensity to show the evolution of the bright elements. The field of view is 220.5 by 182 Mm. Back to paper .

. Comment on J1842+7946 . Comparing the brightnesses of the two main features seen in our 5 GHz image with higher frequency VLBI images available in the literature (at 8.4 GHz from the USNO database and at 15 GHz by Kellermann et al. (1998)), one can conclude that the NW component has a steeper spectrum since the SE one becomes relatively stronger as the observing frequency increases. VLBApls home page .

... The motion of energetic ions and electrons through space is strongly constrained by the local magnetic field. The basic mode is rotation around magnetic field lines, while at the same time sliding along those lines, giving the particles a spiral trajectory. On typical field lines, attached to the Earth at both ends, such motion would soon lead the particles into the atmosphere, where they would collide and lose their energy. ... In this way the Earth holds on to its radiation belts. ...
