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. MK4: Very small, low lying loop/cavity in MK4 at start of day on west limb on south side of helmet. Disappears. No clear front. Changes in helmet - is a cavity moving outward through the helmet? 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.

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).

Large filament to the NW of this also shows activity at this time. 6/05/2002 2002d156 Mk4 data: 17:36 -> 22:35 It looks as though part of the large prominence that just passed over the west limb lifts up and while much of the material drains down along either side of the loop while lifting- a piece seems to erupt (19:15-19:48). 6/06/2002 2002d157 Mk4 data: 16:52 -> 22:23 Huge erupting prominence from behind the NE limb at the beginning of the observing day- shows possible helical structure. Also visible in Mk4.

Some flows along an S-shaped filament close to SW limb. 6/12/2002 2002d163 Mk4 data: 17:13 -> 22:18 Active prominence at PA 110-120. Some material appears to get pushed up and the down behind the limb (~19:00)- don't think anything erupts. No significant disk activity. 6/13/2002 2002d164 Mk4 data: 18:08 -> 24:34 No significant limb activity. Small area on disk surging and flaring for a long period of time- located at ~PA 260, 0.6R (activity starting at ~18:42 and lasting all day). 6/14/2002 2002d165 Mk4 data: 16:23 -> 19:46 No significant limb activity. A filament in the SE shows motion toward the SE- the velocity data indicates that the material is mostly draining down, but the filament disappears in the H-alpha data after these flows are visible. Some flaring very near west limb (PA 255) at 17:17- SOHO has bad data- hard to tell if there is a CME there. 6/15/2002 2002d166 No MK4 data. No significant disk activity. Some activity on NE limb very close to surface (unable to see in PICS limb data due to clouds)- might be post-eruption loops resulting from an earlier CME seen in LASCO. 6/16/2002 2002d167 Mk4 data: 17:46 -> 20:48 No significant limb or disk activity. 6/17/2002 2002d168 Mk4 data: 16:32 -> 22:11 Large prominence covering a good portion of the NW limb has a piece of material erupting poleward (north) at the beginning of the day, followed by a larger piece erupting (more radially) starting at ~20:12. Simultaneous to the larger erupting piece of prominence material is an erupting filament and two-ribbon flare near the SW limb (~PA 250). Motion along an apparent neutral line at the NE limb (~PA 45-75) at ~19:12. This moving material can be seen popping above the limb at ~19:18, although nothing seems to be erupting. LASCO only sees a very faint, small CME in the NW at ~22:15. 6/18/2002 2002d169 Mk4 data: 21:27 -> 22:07 Cloudy day- no visible limb activity.

This eruption seems to be from an active region very near the limb; it is visible in EIT He 30.4 nm, which is observing during this period. Active filament PA 300-310, 0.95R; probably part of prominence system described above. 11/27/2002 2002d331 Mk4 data: 17:14 -> 22:04; PICS 17:05-22:05; CHIP 17:05-22:03 Active prominences: 85, 105, 135, 230-260, 300.

Active prominences PA 70, 90, 115, 210, 225-265, 315. The prominence extending from PA 225 to PA 265 is exceptionally large (extends to 1.3R) and active, exhibiting highly complex motions; it erupts the following day, appearing in LASCO C2 after 10:00. 12/01/2002 2002d335 Mk4 data: 17:40 -> 22:06; PICS 17:29-22:04; CHIP 17:14-22:05 Active prominences PA 80-105, 115, 210, 260, 290, 315.

Active prominences PA 80, 120, 215, 290, 320. Surging off limb PA 80-90, 255-265. Apparent prominence eruption PA 320, beginning ~18:10; may be associated with large CME centered at PA 320, entering LASCO C2 field of view at 17:54. This has the appearance of a halo CME a bit later, but more likely is nearly simultaneous with another CME (see below). Downflowing material at PA 80 just after 21:00; appears like post-eruption loop material, but is more likely material associated with the erupting filament near this position angle (see below). Filament at PA 75, 0.8R is active from beginning of day and disappears, with outflow signal in CHIP--presumably erupting. There is a pair of EIT dimmings as well as flaring (PA 75, 0.55R) seen in PICS and CHIP. The filament appears connected to the flaring region (although it is on the other side of the active region) and may actually be much nearer the flaring region than appears because of projection effects for high-lying filament material. This filament eruption and flaring appear associated with a separate CME (see above), which together with the CME at PA 320 give the appearance of a halo CME. 12/03/2002 2002d337 Mk4 data: 17:20 -> 22:02; PICS 17:21-22:03; CHIP 17:20-22:03 Active prominences PA 45, 85, 210, 240, 260, 320 Surging from active region PA 80, 0.95R.
