Flaring in active regions along an arc from PA 60, 0.5R to PA 110, 0.9R. 3/31/2002 2002d090 Mk4 data: 17:31 -> 21:15 No coronal activity in raw data. Filament eruption from PA 50, 0.5R, ~20:00; could be associated with slow LASCO CME centered at PA 70, beginning well before filament eruption. Active prominence PA 235. Two very large active filaments: one at PA 150, 0.8R to PA 220, 0.4R; the other at PA 120, 0.9R to PA 90, 0.5R. 4/01/2002 2002d091 Mk4 data: 17:07 -> 19:28 No coronal activity in raw data. No significant disk or limb activity. 4/02/2002 2002d092 No MK4 data. Very cloudy day. No significant (observable) disk or limb activity. 4/03/2002 2002d093 No MK4 data. 4/04/2002 2002d094 Mk4 data: 17:19 -> 22:26 Start of a CME visible at the end of our observing day at PA 100. Suspended active prominence at PA 240. Eruption (possibly of a small filament) at PA 260, 0.1R, ~19:45. 4/05/2002 2002d095 Mk4 data: 17:15 -> 18:53 Only one good Mk4 image- no activity. Cloudy day; few good limb and disk images; no observable activity. 4/06/2002 2002d096 Mk4 data: 17:22 -> 22:21 CME at PA 135 starting at ~20:40- LASCO sees a CME at the same time centered at ~PA 95. Surging off limb: PA 85 (along loop); PA 113, 128, 395. Active, possibly eruptive prominence PA 65, ~17:30. Active prominences: PA 110, 240. Active filaments: PA 10, 0.6R; PA 265, 0.3R. 4/07/2002 2002d097 Mk4 data: 17:25 -> 21:03 No coronal activity in raw Mk4 data, but LASCO sees a faint CME at PA 100 starting at ~21:50. Active prominences: PA 40, 235. 4/08/2002 2002d098 Mk4 data: 17:46 -> 17:49 No coronal activity- only a couple of Mk4 images. Surge near limb at PA 65 at ~19:12 (also seen in PICS limb data). Flows seen in large filament in NW (along the spine). 4/09/2002 2002d099 Mk4 data: 20:02 -> 20:58 Did not look at Mk4 data. Surge in NE and simultaneous motion along a filament in SE at ~21:00. Also an erupting loop prom. at PA 105 at the same time. 4/10/2002 2002d100 Mk4 data: 17:22 -> 22:17 No coronal activity in raw Mk4 data, but LASCO sees a CME at PA 200 at ~19:25. Mk4 has a data gap from 18:13 to 18:42, so this might be when the CME takes off (or it might not be visible in the raw data). Large flare and possible wave in NE at ~19:05. Material is also erupting from this area. 4/11/2002 2002d101 Mk4 data: 19:17 -> 22:02 No coronal activity in raw Mk4 data. Active prominence PA 85 to PA 105. Post-eruption loops PA 65. 4/12/2002 2002d102 Mk4 data: 16:51 -> 21:59 No coronal activity. Flaring in active region PA 310 0.65R; possible small filament eruption. Active prominence system PA 280-305. Active prominence PA 220. 4/13/2002 2002d103 Mk4 data: 17:28 -> 22:08 No coronal activity. Some surging on the disk near sunspot near NW limb at ~20:40 until the end of the day (also seen in limb data). Only a few CHIP images. Fairly cloudy day. 4/14/2002 2002d104 No MK4 data. Very cloudy day- no visible limb or disk activity. 4/15/2002 2002d105 Mk4 data: 18:45 -> 22:05 No coronal activity, but not a very good day of data. Cloudy day, but PICS limb sees what appears to be a large erupting prom. in west in one frame (18:02). Erupting filament near west limb (~PA 260) at 17:13- this must be the one that PICS limb sees. There is also a small two-ribbon flare associated with it. 4/16/2002 2002d106 Mk4 data: 17:24 -> 22:35 No coronal activity, but mostly bad data. No disk activity. Possible post-eruption loops on west limb (also seen in EIT). Prom. on SW limb that is suspended shows some draining. 4/17/2002 2002d107 Mk4 data: 17:26 -> 21:49 Possible prominence material seen to disappear in Mk4 at the very beginning of the day- probably associated with a CME seen in LASCO at PA 110 starting at ~17:00. Large quiescent filament near NE limb. Lots of activity on the west limb- prom. in a loop shape (~PA 260) has either lifted up or erupted right at the beginning of our observing day, and we see lots of subsequent draining and falling back to the surface. Right to the north is prominence material suspended high with draining below it to the surface. Also a long thin surge at PA 300 at ~19:45. 4/18/2002 2002d108 Mk4 data: 17:36 -> 19:27 No coronal activity in raw Mk4 data, but fairly short day. Filament just north of center disk shows motion toward the NE at the same time that a faint filament in NE appears to erupt. These do not seem to be associated with a CME in the NE like I expected. There are a couple of other CMEs in the south and southwest seen by LASCO. 4/19/2002 2002d109 Mk4 data: 16:50 -> 19:21 No coronal activity- quiet in LASCO also. Post-eruption loops in the west, apparently associated with two earlier LASCO CMEs. Tall, suspended (spider) prominence PA 245, with draining. 4/20/2002 2002d110 No MK4 data. No good PICS limb data. Active filament PA 250, 0.9R. 4/21/2002 2002d111 Mk4 data: 17:34 -> 22:09 No coronal activity, but mostly bad Mk4 data. Note: this is the day of the X-flare and event caught by TRACE. Beginning of day (17:35) spectacular ejection of material off limb (PA 265) in progress. It is possible that this material follows a completely loop-like trajectory extending to 1.2R, and that none (or at most a tiny amount) escapes. This is near the same position angle of the X-flare and large mass ejection occurring near 0100. Post-eruption loops PA 255, PA 295. Active prominences PA 80, PA 225. Active filament extending from PA 120, 0.8R to PA 150, 0.4R. Surging on disk PA 80, 0.7R. 4/22/2002 2002d112 Mk4 data: 16:49 -> 21:11 No coronal activity in raw Mk4 data. Active, suspended prominence PA 75. Condensation followed by draining PA 255, beginning ~19:30. Coronal rain PA 260-280. Low, active prominence PA 270. Active filament PA 250, 0.6R. Long active filament of April 21 still showing activity. 4/23/2002 2002d113 Mk4 data: 16:51 -> 21:20 No coronal activity, but most of the data was bad. Cloudy day; few good PICS limb images. Suspended prominence PA 75 showing substantial draining. Apparent post-eruption loops southwest to west. Active filaments PA 290, 0.9R; PA 140, 0.5R (see past two days for activity in this latter, long filament. 4/24/2002 2002d114 No data taken at MLSO today. 4/25/2002 2002d115 Mk4 data: 17:05 -> 21:32 No coronal activity in raw Mk4 data.

LASCO sees a nice CME in SW at ~19:00. Cloudy day; only a few good limb images. Prominence eruption PA 315, beginning ~18:00; probably associated with LASCO CME centered at PA 310, appearing in C2 ~17:00. Large filament eruption centered near PA 200, 0.6R, underway at the beginning of the observing day (16:48). Corresponds to LASCO CME centered near PA 210, appearing in C2 after !8:30. Active filament PA 60, 0.75R. Active prominences: PA 65-95; PA 260; PA 285. 4/27/2002 2002d117 Mk4 data: 17:18 -> 22:07 Data quality is poor. No apparent solar activity Slow CME seen in LASCO in northeast most of day ending on April 28. Motion not apparent in MK4 probably due to poor MK4 data quality and the very low speed of the event. Lots of active prominences, both large and small: PA 60-85; PA 125; PA 220-310. Mildly active filament extending from PA 145, 0.7R to PA 205, 0.6R. Minor flaring in northern active region belt. 4/28/2002 2002d118 Mk4 data: 18:42 -> 21:43 No visible activity. Data are a noisy in the far field of view. Getting very noisy by 20:00. LASCO CME between 18:27 and 18:51 in southeast. Some minor brightening in CME region earlier. CME not visible in MK4 data beginning at 18:42. CME may be off-limb, or in noise in far field. Prominence activity much like preceding day (02d117). Small active filament in active region at PA 260, 0.9R. 4/29/2002 2002d119 No Mk4 data taken at MLSO today. 4/30/2002 2002d120 No MK4 data. 5/01/2002 2002d121 No MK4 data.

Very cloudy day; only a couple of usable PICS limb images. Prominence at PA 230 slowly rises from ~16:45 to ~18:45 and then slowly erupts; also seen in EIT(~19:13) and LASCO(~19:50). Active prominence PA 115. 5/08/2002 2002d128 No MK4 data. Very cloudy day.
