The paper presents the results of analysis geometric characteristics sunspots for period 19-24 cycles activity. shape was studied on basis method normalization images to study average profile spot. deviation from axisymmetric configuration is investigated. It found that spots, as a rule, have an ellipsoid shape, and major axis ellipse has predominant inclination equator, opposite in Northern So...

The Sun provides the energy required to sustain life on Earth and drive our planet's atmospheric circulation. However, establishing a solid physical connection between solar tropospheric variability has posed considerable challenge. canon of is derived from 400 years observations that demonstrates waxing waning number sunspots over an 11(-ish) year period. Recent research demonstrated significa...

â  abstract geographical placement of iran especially azerbaijan area in highly strips and alpine-himalayan seismic, causes the earthquakes and their damages as inevitable facts in our country. for this reason, recognition of parameters affecting occurrence of earthquakes and development of new and suitable methods for prediction is necessary in azerbaijan region. analyzing the complex spatio-t...

"Magnetic clouds" (MCs) are a subset of interplanetary coronal mass ejections (ICMEs) characterized by e n h a n d magnetic fields with an organized rotation in direction, and low plasma p. Though intensely studied, MCs only constitute a fraction of all the ICMEs that are detected in the solar wind. A comprehensive survey of ICMEs in the nearEarth solar wind during the ascending, maximum and ea...

We attempt to correlate all of the available solar-neutrino capture-rate data with the strong magnetic fields these neutrinos encounter in the solar interior along their Earth-bound path. We approximate these fields using the (photospheric, magnetograph-measured) surface magnetic flux from central latitude bands, time delayed to proxy the solar interior. Our strongest evidence for anticorrelati...
