This is a very large event, involving well over 90 ° of the southern polar
crown filament and its NW-ward extension. There are at least three phenomena
obvious in the corona at ~ 1.5 MK (Fe XII):
- The SE-NW extension of the filament channel toward the W limb begins to
show a brightening arcade in the 1997 February 6 22:38 UT image.
- Changes in the polar corwn filament channel can be seen from at least
1997 February 7 00:12 UT.
- There is a brightening, perhaps connected with an Eward eruptive event,
near the E end of the south polar crown filament channel visible starting
in the 1997 February 7 01:48 UT image.
In case it isn't obvious, this is really preliminary and may well
be wrong, partially or totally. So exercise a little rational thought before
accepting anything said on this page.
