This document provides information & images about Coronal Mass Ejections [CME] which have been recorded by the Mauna Loa Solar Observatory [MLSO], which is located on the island of Hawaii. This page is supported by a grant from the National Space Weather Program.
These three images were recorded on August 17, 1989 by the Mark-III K-Coronameter Telescope at the Mauna Loa Solar Observatory. They show a coronal mass ejection (southeast or lower left corner) as it moved outward through the field of view at an estimated speed of 2000 kilometers per second (4.3 million miles per hour).

Solar Maximum Mission (SMM) Coronal Mass Ejection Data
This will link you the the SMM Coronal Mass Ejection homepage
containing a selection of coronal mass ejection images
from the SMM data set and the catalogue of coronal mass ejection events
recorded by the SMM coronagraph in 1980 and 1984 through 1989.
Other Coronal Mass Ejection Web Sites
Links to a variety of sources about CMEs.
Any Mauna Loa images provided on our web page (and FTP site) may be used
by the scientific community for research purposes.
We welcome collaborations with other scientists
in studying coronal mass ejections.
However, no collaboration with High Altitude Observatory (HAO) members
is required and no proposals need be submitted for approval.
