摘要

This presentation focuses on a possibility of creation of a twisted magnetic flux system in the multipolar active region NOAA 8636 on 1999 July 19 as a subsequence of interaction of low-lying coronal loops. It is speculated that the flare that occurred in the active region destabilized the overlying magnetic arcade and triggered a coronal mass ejection, which was observed with the Large Angle and Spectrometric Coronagraph (LASCO) instrument on board the SOHO satellite. The flare was also observed in H-α at Modra Astronomical Observatory in Slovakia.
