8 May 2000 Planets and the Sun
full-halo coronal mass ejection Coronagraphs on board the orbiting ESA/NASA Solar and Heliospheric Observatory recorded a full-halo coronal mass ejection at 1230 UT on Sept. 12. In this image, the faint red-colored circle shows the true size of the Sun. The solid brick-colored region denotes an occulting disk that blocks the bright glare of the Sun to reveal the fainter corona.
CME and Particle Storm of July 14, 2000 A fast (1775 km/s), earthward directed coronal mass ejection (CME), an X5.7 flare near central meridian, the largest solar energetic particle (SEP) event of the current solar cycle --- do they add up to "the big one?" Detectors on the ACE, WIND, POLAR, and SOHO spacecraft have all seen (and in some instances, been swamped by) "nature's wrath" in the form of energetic particle saturation.
SOHO observations of two sungrazing comets 1998 June 2 Play the upper blue one.
Shortly after the comets disappeared behind the occulting disks of the LASCO C1 and C2 coronagraphs, a bright coronal mass ejection (CME) with an enormous erupting prominence appeared on the southwest (lower right) limb of the Sun. (East and West are reversed in heliographic coordinates to match the compass directions for an earthbound observer.) The prominence eruption is visible in the SOHO EIT images.

Cinema EIT: Movies from the SOHO Extreme ultraviolet Imaging Telescope Lots of movies! Many neat, some less interesting.
observation of an eruptive prominence/CME on the SW limb A large eruptive prominence goes into emission, post-CME loops (PCMEL's) appear, and a proton storm starts (not so eaily visible in 512 x 512 versions here; the original data are 1024 x 1024).
