2
The erupting active region is near disk center
and is, relatively speaking, isolated.
3
The photospheric magnetic structure of AR 10759
closely resembles that of AR 8038, from the May
12, 1997 event.
4
Big Bear has 1 hr. of 1 min. cadence vector
magnetograms leading up to the event.

• Vector magnetograms prior to CMEs are necessary
  for realistically modeling such events, but are
  rare.

5
Theres at least one TRACE 171 image of the
corona prior to the flare onset.There is also
SXI coverage before and during the flare.
6
In addition, the flare has H? coverage, and...
7
TRACE 1600 Å coverage, with ribbons and all
though I didnt make a movie!
8
RHESSI also observed the flare, although the
spacecraft was in the S. Atlantic Anomaly for a
time.
9
GOES indicates that the flare, near 1700 UT, was
slightly weaker than X-class.
10
The CDAW CME catalog lists this HALO CMEs speed
as 1689 km/s but from just two points in C2.
C3 has more data, but some is poor.
11
ACE caught a clear signature of the incoming flux
rope 1.25 days later, with a clear southward Bz.
12
In the resulting geomagnetic storm, the DST index
dipped below 200.
