Session 1 - Chromosphere, Corona, Flares.
Display session, Friday, June 27
Ballroom B, Chair: Charles Kankelborg
The SOHO Extreme ultraviolet Imaging Telescope (EIT) recorded a series of events on April 1, 1997 with a 12-minute cadence of 195 Angstrom (Fe XII) images. A Moreton wave was observed emanating from a flaring active region beginning at 13:56 UT 1-April-1997. The wave travelled at initial speeds of approximately 300 km/sec, spreading across the solar disk radially from the flare. The CME observed by SOHO/LASCO was observable at both the east and west limbs in the C2 (2-6 solar radii) and C3 (3.7-30 solar radii) coronagraphs. The event was the site of strong emerging flux, and a number of explosive jet-like surges were observed at the east edge of the region prior to, throughout, and following the event.
The discussion will include topology, comparison to Moreton wave/MHD theory predictions, and solar wind signatures.
