Apparent post-eruption activity is visible in EIT 195. 8/10/2000 2000d223 Mk4 data: 16:35 -> 21:39 No coronal activity Tall prominence just south of east with significant downflows. 8/11/2000 2000d224 Mk4 data: 16:38 -> 22:06 No coronal activity EPL at ~PA 110, ~19:50; no obvious LASCO CME, but possible continuous outflow in C2 near this PA, during this period.

Erupting filament (centered at PA 103) in progress at beginning of day (CHIP velocity); one end (PA 98) crosses limb at ~16:52 and appears in PICS limb image at ~16:59. No major LASCO signature, but continual outflow in this region, and clear eruptive events several hours earlier and later. 8/19/2000 2000d232 Mk4 data: 16:59 -> 22:02 No coronal activity. Erupting filament accompanied by two-ribbon flare at PA 293; corresponding EIT flare; no LASCO association. 8/20/2000 2000d233 Mk4 data: 19:27 -> 20:13 No coronal activity seen (very short day).

This CME does not have a coherent structure, but there is evidence of something moving outward (also seen in LASCO). This may be a CME observed in some sort of projection (maybe edge-on?). No evident association with PA 230 CME in limb or disk data. Dramatic eruption ~17:00 from AR at PA 135 seen especially well in CHIP data; no apparent LASCO association. 8/29/2000 2000d242 No MK4 data. 8/30/2000 2000d243 Mk4 data: 16:58 -> 18:06 Cloudy day, few good Mk4 images, no calibration.

Small two-ribbon flare in SE at ~17:25. 9/07/2000 2000d251 Mk4 data: 16:51 -> 20:17 Faint CME detectable in Mk4 in NE (clearly visible in LASCO). Cannot determine the width in Mk4. Large AP on SE limb. 9/08/2000 2000d252 Mk4 data: 17:20 -> 18:53 No coronal activity. 9/09/2000 2000d253 No data taken at MLSO today. 9/10/2000 2000d254 No data taken at MLSO today. 9/11/2000 2000d255 Mk4 data: 17:08 -> 21:44 No coronal activity. 9/12/2000 2000d256 Mk4 data: 16:44 -> 20:51 CME at PA 60 starting at ~17:04, with a width of ~80 degrees. Huge EP associated with the above mentioned CME. Looks like the event occurs on the other side of the disk. 9/13/2000 2000d257 Mk4 data: 17:03 -> 21:10 Bad Mk4 data. No PICS data. No significant disk activity. 9/14/2000 2000d258 Mk4 data: 17:11 -> 22:00 No coronal activity. No significant disk activity. 9/15/2000 2000d259 Mk4 data: 16:38 -> 22:05 No coronal activity. No significant disk activity. 9/16/2000 2000d260 No data taken at MLSO today. 9/17/2000 2000d261 No data taken at MLSO today. 9/18/2000 2000d262 Mk4 data: 16:51 -> 20:51 Bad Mk4 data- could not calibrate. No significant disk activity. 9/19/2000 2000d263 Mk4 data: 16:41 -> 22:02 Slow, small CME at ~PA 240 starting at ~18:20. More material seen moving out at PA 200-210 at ~20:38, which is either a separate CME or part of the larger one mentioned above. Slow EP at PA 200-210 at ~20:14 (this is the material mentioned above). This originates behind the limb. No significant disk activity. 9/20/2000 2000d264 MK4 data: 17:02 -> 22:10 No coronal activity, but data isn't great (bright sky). No significant disk activity. 9/21/2000 2000d265 No MK4 data. Very cloudy day; poor disk and limb data. 9/22/2000 2000d266 Mk4 data: 17:02 -> 22:02 Very narrow CME at PA 300, starting at ~19:40. This CME is also seen in LASCO. Strong surging from near sunspot just north of disk center. 9/23/2000 2000d267 Mk4 data: 16:57 -> 21:34 Very narrow CME (prominence material?) at PA 300 near the end of the observing day. Looks like this is part of a larger CME seen in LASCO. Continual surging in AR near disk center. 9/24/2000 2000d268 Mk4 data: 17:24 -> 21:59 Some material is seen in Mk4 lifting off at PA 90 at the very end of the observing day. A swelling is also seen in LASCO, but no typical CME is seen. From EIT, CHIP, and PICS, this event looks as though it should have produced a much more major CME, although only a small amount of prominence material appears ready to escape. 9/25/2000 2000d269 Mk4 data: 18:29 -> 20:48 Very active prominence near PA 100 9/26/2000 2000d270 No MK4 data. 9/27/2000 2000d271 Mk4 data: 17:09 -> 22:06 Too cloudy for any Mk4 observations.

Significant flows in long, looping filament north of disk center. 9/28/2000 2000d272 Mk4 data: 16:56 -> 20:04 No coronal activity. Persistent flows along filament apparently connecting two active regions in east to southeast. 9/29/2000 2000d273 Mk4 data: 16:50 -> 22:12 CME at PA 135 starting at ~18:00 (Loop/cavity/core structure). This CME doesn't show up in LASCO until 21:00. Disk activity possibly associated with the above CME (but occuring after it is seen in Mk4)- some surging and lifting of material from the AR/sunspot in the SE. This occurs at ~ 19:50. 9/30/2000 2000d274 Mk4 data: 00:09 -> 21:37 Large, fast CME centered at PA 100 starting at ~ 17:45. Other activity seen at PA 70 appears to be another, slower CME, but all looks like one event in LASCO. Prominence material quickly erupts from PA 100 during the large CME. No significant disk activity. 10/01/2000 2000d275 Mk4 data: 17:05 -> 21:23 No coronal activity. No significant disk or limb activity. 10/02/2000 2000d276 Mk4 data: 17:03 -> 22:07 Small filament eruption with a large circular flare just southeast of sunspot, which is south of disk center. LASCO shows a faint halo CME in the south. Flare and filament eruption seem to occur at very nearly the same time. What appears to be surging follows flaring. 10/03/2000 2000d277 Mk4 data: 16:50 -> 21:59 No coronal activity. No significant disk or limb activity. 10/04/2000 2000d278 Mk4 data: 17:07 -> 22:02 No coronal activity.

Active prominence in northeast with flows parallel to the limb extending some 30 degrees; flows in both directions. 10/12/2000 2000d286 Mk4 data: 16:48 -> 19:56 No coronal activity. Prominence in northeast shows motion that looks very much like an eruption with most of the material falling back, but there is no associated LASCO CME. 10/13/2000 2000d287 Mk4 data: 16:45 -> 21:22 No coronal activity. Surging off limb from AR just north of west. 10/14/2000 2000d288 Mk4 data: 16:56 -> 21:15 No coronal activity. Surging off limb in the west. 10/15/2000 2000d289 Mk4 data: 16:52 -> 16:55 Very cloudy. Short day. No significant disk or limb activity. 10/16/2000 2000d290 Mk4 data: 16:55 -> 19:27 No coronal activity- very noisy data. No significant limb or disk activity. 10/17/2000 200d291 Mk4 data: 17:27 -> 21:58 Only one good Mk4 image- unable to detect any activity.

Filament eruption in northeast, apparently corresponding to Mk4 CME. Filament already active at beginning of observations (~17:00) and has fully erupted by the time of the last good data (~19:50). 10/29/2000 2000d303 Mk4 data: 16:56 -> 20:51 No coronal activity. Huge EP in NW toward the end of our observing day- unfortunately the Mk4 and PICS data is bad around this time.

Prominence at PA 115 drains from ~1.25R and disappears completely. Apparently associated with Mk4 CME, which appears as a slow CME in LASCO. 11/09/2000 2000d314 Mk4 data: 17:01 -> 21:58 Bad Mk4 data. Bad PICS data; little good CHIP data. 11/10/2000 2000d315 Mk4 data: 17:01 -> 22:01 CME centered at PA 260 with a loop/cavity/core structure from ~18:40 - 21:30.

Large, slow filament eruption with two-ribbon flare in the south; slow LASCO CME. Small filament eruption in the northwest; narrow LASCO CME (this narrow CME is also seen in Mk4). 12/19/2000 2000d354 Mk4 data: 17:34 -> 22:01 Faint, apparently small CME centered at ~PA 250 starting at ~18:40. Strong surge with flare from active region north of east. 12/20/2000 2000d355 Mk4 data: 17:31 -> 22:08 CME centered at PA 305 starts at 20:00. This CME has a nice loop/cavity/core structure. Large prominence eruption corresponding to above CME. 12/21/2000 2000d356 No data taken at MLSO today. 12/22/2000 2000d357 Mk4 data: 17:31 -> 22:02 No coronal activity. No significant disk or limb activity. 12/23/2000 2000d358 Mk4 data: 17:35 -> 19:57 No coronal activity. No significant disk or limb activity. 12/24/2000 2000d359 Mk4 data: 17:26 -> 22:02 Two CMEs- one at PA 130 (from ~18:00-20:00), and another at PA 215 (from ~19:30-end of day). Both CMEs have a visible loop/cavity/core structure. Two EPs associated with the CMEs- the first one at PA 130 is a front side event, while the second one (PA 215) is a backside event. 12/25/2000 2000d360 No data taken at MLSO today. 12/26/2000 2000d361 Mk4 data: 17:30 -> 22:07 No coronal activity. No disk activity. Large, quiescent prominence in the SE. 12/27/2000 2000d362 Mk4 data: 17:27 -> 22:46 No coronal activity. Partial EF just SE of disk center at the beginning of the observing day. 12/28/2000 2000d363 No data taken at MLSO today. 12/29/2000 2000d364 Mk4 data: 17:31 -> 22:02 No coronal activity. No significant disk activity. 12/30/2000 2000d365 Mk4 data: 17:49 -> 22:08 No coronal activity. EF in SW at ~19:00. 12/31/2000 2000d366 Mk4 data: 17:35 -> 20:33 No coronal activity. No significant limb or disk activity.
