From plunkett@kreutz.nascom.nasa.gov Wed Jun 7 20:40:40 2000 Date: Wed, 7 Jun 2000 20:24:48 +0000 (GMT) Subject: Halo CME on 2000/06/07 LASCO and EIT observed a halo CME today, 2000/06/07. The event was first visible as a faint diffuse front over the N and W limbs in C2 at 16:30 UT, and extended all around the occulter in the next image at 17:08 UT. There appears to be a second ring of enhanced brightness at 17:30 UT, probably a second phase of the same event. The CME was probably associated with an X1.2 flare in AR 9026, located near central meridian at about N20 E02. This flare was observed by EIT at 15:36 UT. Images and movies (currently only EIT and C2) are available at the LASCO ftp site: ftp://ares.nrl.navy.mil/pub/lasco/halo/20000607. More information, including a speed estimate, images and movies, will follow when more data becomes available from C3. Best wishes, Simon Plunkett. +----------------------------------------------------------------------+ | Simon Plunkett, E-mail: plunkett@kreutz.nascom.nasa.gov | | USRA, Mail Code 682.3, | | NASA Goddard Space Flight Center, Phone: +1-301-286-2941 | | Building 26, Room G-1, +1-301-286-3447 | | Greenbelt, MD 20771.
