CORONAS-PHOTON Observes Spike of Solar ActivitySpike of solar activity was registered by TESIS observatory installed on Russian satellite CORONAS-PHOTON within previous two days. This is caused by two new active areas which were numbered 1028 and 1029 in NOAA (National Oceanic and Atmospheric Administration, USA) catalogue. The area numbered 1027 disappeared on Oct. 27. In other words, the spike of solar activity started after a pretty long calm period of three weeks. We can only guess how much energy our star has cumulated and what would it use for.During the previous activity spike in late Sept., the excessive energy of the solar crown resulted in burst of level C2.0 (second-high capacity this year), as well as a protuberance on the night of Sept. 26 27. Both appeared on the eastern edge of the Sun, that`s why there was no impact on the Earth, since geoactivity of this edge is the lowest among the solar longitudes turned towards our planet. Though both new areas are located in the northern part of the Sun, their parameters differ a lot. Area 1028 is a single spot visible from the Earth only via high-res equipment, area 1029 is the largest group this year, which stretches along the solar parallel, and it counts 18 spots. In addition, it evolves rapidly: there were only 11 spots on Oct. 25; the day before, it was 9 spots; and the area didn`t exist on Oct. 23 at all. This evolution shall be followed by cumulating high electrical energy in the solar atmosphere. The latter comes from magnetic hydrodynamics- the force of electrical field in plasma is proportional to magnetic field evolution rate. Thus, very powerful electrical current (circle usually) are generated in the growing areas on the Sun. They grow within many hours, until the current circle is broken due to some random process, and the energy cumulated is outburst. This is modern representation of the solar burst processes.
