SOHO observations of two sungrazing comets
1998 June 2

SOHO is a program of international cooperation between ESA and NASA.

Read the text of the NASA press release.

On Tuesday, 1998 June 2, telescopes on board the SOHO spacecraft viewed two sungrazing comets following similar but not identical orbits, and entering the tenuous outer atmosphere of the Sun --- the solar corona --- never to reappear on the other side of the Sun.

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.
