... Electric field is a potential heat source for ionospheric particles (Rees, 1989). It is due to the fact that, under the action of an electric field, charged particles drift relative to one another and relative to neutral particles. ... This is called frictional heating. ... However, the effect of frictional/Joule heating of neutrals in the auroral electrojet region can lead to upward neutral wind in a region of high electron densities and strong electric fields (Winser et. al., ...

... Newton's Laws . ... If object A exerts a force F on object B, . then object B exerts an equal and opposite force ?F on object A" . ... There exists a whole set of situations where two equal and opposite forces act on the same object, canceling each other so that no acceleration (or even no motion) occurs. ... It is all in Newton's third law: as your legs propel your body towards the dock, they also apply to the boat an equal force in the opposite direction, which pushes it away from the dock. ...

. I measured my limiting magnitude on this picture at about Mag 18.9. I also did some photometry near for the SN positon, and I found a star liked object at about Mag 17.6. I think this object is 1999br. This image is deconvoluted, but I measured the magnitude pre-deconvulution. Kereszty Zsolt . Hungary, Miskolc . Back to Bright Supernovae .
