Solar Flare Origin - critical analysis" Lev Pusti'lnik We analyze current approach to solar flare origin in 3 aspects: a. Pre-flare equilibrium state of current-magnetic structure above active region and its evolution to flare state, b. Possible reasons of stability loss with transition of system in flare state c. Flare energy release in turbulent current sheet and particle acceleration in this system. ...

PENTICTON SOLAR RADIO FLUX VALUES (from SGD Explanation of Data Reports) Daily Solar Flux Values - Penticton -- Daily measurements of the integrated emission from the solar disc at 2800MHz (10.7cm wavelength) have been made by the National Research Council of Canada since 1947. ...

Short-Period Comets: Origin and Terrestrial Impact Hazard . ... The model is consistent with the basic observed distributions of near-parabolic comets, short-period comets, Centaurs and high-eccentricity trans-Neptunian objects.This model requires that initial objects in the early Solar System are concentrated to the outer planetary region, and the physical lifetime of comets in the inner planetary region at the present epoch is an increasing function of initial perihelion distances. ...
