The following is a list of activity as seen by the observers at the Mauna Loa Solar Observatory (MLSO) in Hawaii. Additional information may be added by the personnel at the High Altitude Observatory (HAO) where the data is processed and analyzed. The initials of the HAO personnel are indicated in parenthesis. Dates are given by calendar day and by year/day-of-year. Key of abbreviations: ADF - Active dark filament AFS - Arch filament system AP - Active Prominence APR - Active Prominence Region AR - Active Region ASR - Active Surge Region BOU - Boulder, Colorado Observatory BSD - Bright surge on the disk BSL - Bright surge on the limb CME - Coronal Mass Ejection CRN - Coronal rain DPMON - Digital prominence monitor DSD - Dark surge on the disk DSF - Disappearing filament EPL - Eruptive prominence on the limb MDP - Mound prominence MLSO - Mauna Loa Solar Observatory QP - Quiescent prominence PA - Position angle (measured counterclockwise from north pole. eg. east equator = 90 degrees, west equator = 270 degrees) RV - Radius vector UT - Universal Time WL - White light NOTE: (bracketed letters indicate observer's initials) ***************************************************************************** 2/15/80 80d046 CME at PA: 210, from 19:47-21:37 4/6/80 80d097 CME in progress at beginning of data from 17:52-18:10 UT at PA: 75 5/1/80 80d122 Huge CME at PA: 100 from 19:18-19:43 UT. 5/31/80 80d152 CME at PA 100. Event takes place from 18:16-18:54 UT. 7/18/80 80d170 CME at PA: 60 from 20:05-21:31 UT. The CME is very faint and hard to see with all the noise in the background. (djs) 7/29/80 80d181 CME at PA: 260 from 18:26-18:50 UT. It is very fast. (djs) 8/9/80 80d221 CME at PA: 120 from 20:00-20:34 UT. (djs) 8/18/80 80d231 CME at PA: 60 degrees. It is faint and in progress at the beginning of the day. The event takes place from 17:08-18:30 UT. (djs) 8/22/80 80d235 CME at PA: 275 in progress at 17:45-18:04 UT. It remains in the field of view at the end of 18_04. (djs) 9/1/80 80d245 Faint CME at PA: 80 from 17:54-18:20 UT. (djs) 9/20/80 80d264 CME at PA: 30 from 18:37-20:13 UT. It's difficult to see after the intial Prominence Material burst. It is very apparent that the cavity is getting larger throughout the time period of the event. (djs) 10/11/80 CME at PA: 275 from 20:35-21:16 UT. It is very faint to see (djs). 12/31/80 CME at PA: 265 from 19:36-21:37 UT. The CME probably lasts past 21:37 when the observing stops. (djs)
