The erupting active region is near disk center and is, relatively speaking, isolated.

The photospheric magnetic structure of AR 10759 closely resembles that of AR 8038, from the May 12, 1997 event.

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.

There’s at least one TRACE 171 image of the corona prior to the flare onset.
There is also SXI coverage before and during the flare.

In addition, the flare has H coverage, and...

… TRACE 1600 Å coverage, with ribbons and all – though I didn’t make a movie!

RHESSI also observed the flare, although the spacecraft was in the S. Atlantic Anomaly for a time.

GOES indicates that the flare, near 17:00 UT, was slightly weaker than X-class.

The CDAW CME catalog lists this HALO CME’s speed as 1689 km/s – but from just two points in C2. C3 has more data, but some is poor.

ACE caught a clear signature of the incoming flux rope 1.25 days later, with a clear southward Bz.

In the resulting geomagnetic storm, the DST index dipped below – 200.
