ИСТИНА

It is shown that the passage of comet nuclei through the solar chromosphere with velocity more than 600 km/s is accompanied by their aerodynamic crushing and transversal expansion of the crushed matter, that terminate by sharp aerodynamic stopping of the flattened structure in the relatively very thin sub-photosphere layer. The process leads to generation of hot plasma and explosive phenomena. Spectral observations by space observatories like SDO (Solar Dynamics Observatory) are of interest for the physics/prognosis of solar flares // COSPAR 2012 SA, Scientific Session D2.1: CMEs (Coronal Mass Ejections) in the Rising Phase of Solar Cycle 24.
