mlso.events.YYYY ----------------- The following is a list of activity as noted by HAO staff in Boulder, where the MLSO data are processed and analyzed. More information concerning observations at MLSO can be found at http://mlso.hao.ucar.edu. Dates are given by calendar day and by year/day-of-year. First a brief activity report is given for LASCO, and for EIT and MDI, then follows the report for the MLSO instruments. This includes: Mk4 coronal activity, and chromospheric activity off-limb and on-disk as observed in Halpha and HeI by PICS and CHIP. The activity report for the MLSO instruments refers to the observing day, NOT to the calendar day. The typical observing day at MLSO is from ~1700-1730UT to ~0200UT. Key to abbreviations: CHIP The 1083 nm instrument at MLSO, which provides both intensity and velocity information. CME Coronal Mass Ejection Mk4 The white-light coronagraph at MLSO. MLSO Mauna Loa Solar Observatory PA Position angle (measured counterclockwise from north pole. e.g., east equator = 90 degrees, west equator = 270 degrees) PICS The H-alpha instrument at MLSO, which provides both disk observations and occulted off-limb observations. R Solar radius: e.g., 0.9R is 0.9 solar radii from sun center projected onto the plane of the sky. UT Universal time (any notation in the form 17:33 or 1733 refers to 17:33 UT).
