Starting on 9 August 2001, some time before 07 UT, a new active
region began to emerge, later to be called AR 9574. The (QuickTime/JPEG;
8.4MB) (171) movie (of 640 by 480 pixels of 375 km each) shows this
emergence almost from the start, covering a period of 4 days.
Unfortunately, the emergence occurred at the edge of the TRACE field
of view, so that we have full coverage only in what we call the
context images; these are images covergin the full field of view,
but taken at a much lower cadance than the 3/4 field cutouts that
were being made every 20 seconds to study AR 9570 just south of the
new region (visible at the lower edge of the movie).  Until about
20 UT on 9 August the region is compact, and all coronal connections
appear to close onto itself. But then new connections develop, first
to the south, later also northward.

Notice also that the fan of coronal loops emanating from the sunspot
in AR9570 in the south appears to be rotating, at least during the
first half of the movie.
