WAVE PHENOMENA ASSOCIATED WITH THE X3.8 FLARE/CME OF 17-JAN-2005

摘要

We report high-cadence H{sub}α observations of a Moreton wave observed at Kanzelhohe Solar Observatory (KSO), Austria, associated with the 3B/X3.8 flare of 2005 January 17. The Moreton wave can be identified in about 40 H{sub}α frames over a period of 7 min, whereas the associated EIT wave can only be measured on-disk in one frame. First results from distance measurements are presented which reveal a spread in the wave velocity for different directions of wave propagation.
