Abstract

An earth-directed coronal mass ejection (CME) was observed on May 12,1997 by the SOHO Extreme ultraviolet Imaging Telescope (EIT). The CME; originating north of the central solar meridian, was later observed by the Large Angle Spectrometric Coronagraph (LASCO) as a ''halo'' CME: a bright expanding ring centered about the occulting disk. Beginningat about 04:35 UT, EIT recorded several CME signatures, including dimming regions close to the eruption, post-eruption arcade formation, and a bright wavefront propagating quasi-radially from the source region. Each of these phenomena appear to be associated with the same eruption, and the onset time of these features corresponds with the estimated onset time observed in LASCO. We discuss the correspondence of thesefeatures as observed by EIT with the structure of the CME in the LASCO data.
