Subject: MEOC Campaign Target <P></PRE> <P> To MEOC participants,
<P>Today AR 9236 wins the competition for being the new prime MEOC target
for 25 Nov 2000 for producing two X-class flares with halo CMEs, the
latter reported by Simon Plunkett.  Reports of the X-class flares are
from NOAA.  The flares seem to be occurring in association with pockets
of magnetic flux around the leader spot but opposite in magnetic
polarity to the sunspot.  Hence we select the leader spot as the center
for the MEOC target. 
<P>For limited field instruments, the coordinates on the leader sunspot in
9236 for 25 Nov 2000 at 00:00 UT are: <P>N21 W14 X= +217&quot;  Y= 324 
<P>Two other halo CMEs were also reported by Simon during the last two
days.  One is a Thanksgiving day special (for the U.S. holiday). It came
from the MEOC target area and occurred in association with eruption of
the filament on the northeasern boundary of AR9231.  Extensive wave
effects are seen in EIT with this event.  The 4th halo producing event
was in the SE from an area not promising for MEOC.
<P>Thanks to participants who sent brief messages reporting observations of
major events in the previous target region 9231 as well as those who
anticipated and observed one of the the first  two X-class flares in AR9236
<P>Although we are compelled to change the MEOC target to AR9236, we will
not discourage any participant who might have good reason to choose to
follow-up on AR 9231 for events above the limb for another day rather
than changing immediately to observe events in the new target region 9231.
<P>We also feel that it is essential to mention that in choosing AR 9236 as
the prime target, participants might well miss a major impending event
in the active region complex 9240 now over the limb in the NW with a
distinct sunspot and at least two filaments.  The filament just east of
the sunspot in the middle of the region is long and high and has shown
extraordinary Doppler shifts throughout the last 6 hours.  It could
erupt at any time.   <P>Happy observing! &nbsp;&nbsp;&nbsp;
