Evidence that Solar X-Ray Emission is of Purely Thermal Origin (Also Observation of Far UV Flash Durs. Solar minimum conditions are characterized by the presence of only a few plage regions, which dominate X-ray emission below 20 Å. Activity events under these conditions can cause a large increase in flux below 20 Å in coincidence with a decrease in emission between 44 and 60 Å, as the silicon andMeditate 发表于 2025-3-27 03:23:49
Particle Acceleration and Plasma Ejection from the Sunphenomena of solar activity which appear mainly in the course of solar flares. So, in this paper we are interested primarily in solar flares and flarelike phenomena. However, to have a guide to the interpretation of these phenomena it would be useful to say a few words about solar activity as a wholAbominate 发表于 2025-3-27 07:17:30
Particle Diffusion in the Solar Coronaticular an assessment is made of the relative importance of diffusion, drift motions and direct field line connections in the distribution of energetic particles in the corona. Observational evidence on particle flux distributions near the earth is related to the question of storage in the corona. T无节奏 发表于 2025-3-27 11:47:11
Time Variations in Solar Activity sunspot numbers in the present solar cycle (number 20) are found to be similar to those in cycles with maxima in 1937, 1917, 1860, and 1769..Time variations within the 11-year cycle are considered. It is pointed out that all solar latitudes and longitudes do not attain maximum levels of activity atDiverticulitis 发表于 2025-3-27 16:37:13
Composition and Dynamics of the Solar Wind Plasmaind plasma..The solar wind helium content has been determined in several independent series of observations; the long-term average abundance of helium relative to hydrogen is close to 4.5% by number. This ratio is lower than that usually given for the solar photosphere, possibly implying a separatio愤慨点吧 发表于 2025-3-27 19:14:26
