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):

  1. 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.

  2. Changes in the polar corwn filament channel can be seen from at least 1997 February 7 00:12 UT.

  3. 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.
