2017-01-02T02:00:09 --> 2017-01-02T13:00:09
This coronal hole was impressively large. However, not the whole area was permeated by open field lines, in this case of negative polarity. There were bright points here and there, which sometimes showed transient activities including jets.

2017-01-02T08:00:09 --> 2017-01-02T10:00:09
The eruption accompanies whirling motions that also propagated to an adjacent filament on the disk. The corona was hardly affected by this eruption, and no CME resulted.

2017-01-01T06:00:09 --> 2017-01-01T10:00:09
This filament eruption is diffuse and its associated chromospheric flare emission is also weak. No CME.

2016-12-31T22:00:06 --> 2016-12-31T23:00:06
It appears that a minor eruption involving a filament in AR 12622 excited a neighboring longer filament, resulting in two-ribbon emission.

2016-12-30T19:00:06 --> 2016-12-30T21:00:06
The eruption appears to be confined. It was limb-occulted. There was a time lag of the adjecent coronal structure to respond to the eruption.

2016-12-30T03:40:10 --> 2016-12-30T05:40:10
This is probably an ejeciton of mass into a filament due to reconnection at its leg, which is in the periphery of AR 12622.

2016-12-29T02:00:06 --> 2016-12-29T11:00:06
This appears to occur behind but close to the limb. Turbulent motions precede the eruption.

2016-12-28T00:00:06 --> 2016-12-29T00:00:06
This coronal hole was quite eye-catching. There are quite a few bright points inside the coronal hole. The coronal hole is not rooted by open field lines and interchange reconnection could be frequent occuring not only around the coronal hole boundaries but also inside.

2016-12-26T10:40:14 --> 2016-12-26T13:00:14
This is a diffuse eruption, wider than a typical jet. The source region is probably slightly behind the limb.

2016-12-27T11:40:14 --> 2016-12-27T15:40:14
Minor eruptions occurred in succession in adjacent structures, both accompanying temporary dimming.

2016-12-25T17:10:18 --> 2016-12-25T18:10:49
Not as much as in previous events

2016-12-25T15:32:50 --> 2016-12-25T16:33:21
At top of slit, hopefully in ALMA FOV

2016-12-26T03:00:06 --> 2016-12-27T05:00:06
This movie shows coronal activity of AR 12621 before it made into the NOAA database. It was registered to have the spot aera of 10 msh at 27 December 2016 00:00 UT. It grew to 30 Msh the next day, but the coronal activity was less spectacular then. To Ryan: This should bbelong to the object AR. But as we communicated in November 2016, the object window for AR is too big and clumsy for the annotator to close properly. I think the problem I reported yesterday was the same thing as I did in November 2016.

2016-12-25T13:55:22 --> 2016-12-25T14:55:53
Also draining prominence at the top of the slit

During ALMA coordination

2016-12-24T14:29:34 --> 2016-12-24T14:40:14
Another during the ALMA coordination

2016-12-24T15:20:56 --> 2016-12-24T15:29:43
Not sure if this is a coronal jet but the Mg h & k spectra show lots of rotation & dynamics

2016-12-21T09:22:24 --> 2016-12-21T09:33:25
Yes

2016-12-21T08:04:47 --> 2016-12-21T08:16:28
Slit is fixed on what looks like one footpoint, nice high cadence
