... This limited extent suggests that the currents which disturb the field flow somewhere nearby, probably near the auroral arcs. ... Any electric current, however, must flow in a closed circuit, and since it seemed to be caused (like that of the aurora) by processes taking place in distant space, Birkeland proposed that it came down from space at one end of the arc and returned to space at the other end. ... The electric energy needed to drive the current is taken from the motion, which is slowed down....

... What work is currently being done to improve the flux calibration accuracy for echelle modes? ... Starting early in Cycle 11, monthly offsetting for echelle modes was turned off to minimize these types of calibration problems. ... We are currently working on redetermining the echelle flux calibration so that it is self-consistent with the 2-D scattered light algorithm. Time dependence of the sensitivity - Sensitivity-monitor data for the echelle modes are currently under investigation. ...

... Aurora from Space . ... Magnetic Storms . ... The "ring of fire" seen by satellite cameras around the polar caps (picture below) is probably created by electrons leaking from the tail's plasma sheet, whose magnetic field lines form a somewhat imperfect trap. ... One possible explanation involves the close association between auroral arcs and electric currents which flow along field lines between the ionosphere and distant space ( Birkeland currents ). ... Why no aurora at the magnetic poles? ...

Next: Modes of Operation Up: CCD Scientific Performance Previous: Field of View . Thermal excitation of charge carriers from the valence to the conduction band creates a dark current signal which may vary with position in the array, and also has temporal shot noise variation. ... In a device devoid of localized defects which give rise to individual dark current spikes , most dark current arises from electrons generated at interface states at the surface. ...

... According to the current estimates, a few percent of Main Sequence B5-F5 stars reveal strong surface magnetic fields reaching the values of tens of kilogauss, which is an order of magnitude greater than the maximal magnetic field in sunspots. ... An important direction in the study of magnetic stars is the study of binary and multiple systems with magnetic components using the techniques of spectroscopy and high angular resolution interferometry. ...
