Particles of the most recent Solar ejection.

[Rob D]

Could someone comment on the particle constituents of the most recent "solar storm". A look at the films of the SOHO observatory show very marked particle trails on the photo-active medium shortly after a large explosion of 1429.

The print media made mention of two Earth observations, one of particles which arrived in 8 minutes (no, I don't believe it either) followed by magnetic waves which arrived somewhat later.

Astrophysicistsists, know the straight of it?

Many Thanks,
Rob

Which recent event? There have been several, so please specify the date. Sunspot 1429 continues to be active.

Sunspot 1432 far left, 1429 and 1430 upper right, and 1428 lower right.

A CME launched from the sun on March 9th is nearing Earth. According to analysts at the Goddard Space Weather Lab, the cloud will arrive on March 11th at 0649 UT (+/- 7 hr). This is not a particularly potent CME. Nevertheless, high-latitude geomagnetic storms are possible when it arrives.

Sunspot AR1429 is still erupting this weekend. On Saturday, March 10th, it produced a powerful M8-class flare that almost crossed the threshold into X-territory.
