2017-08-16T06:30:09 --> 2017-08-16T11:30:09
Source AR12671 undergoes confined flaring (no CME signatures in LASCO coronagraphs) and launches a (faint) coronal wave towards the coronal hole. Hints of reflection off the coronal hole boundaries are visible.

2017-08-16T06:30:09 --> 2017-08-17T10:00:09
An observation of a long filament extending towards the solar limb. Towards the limb, where the axis of the filament closely follows the line of sight, a dark cavity is seen in the corona. The bulk of the filament erupts but the cavity stays intact until it vanishes. The cavity vanishes quickly enough to rule out the case of non-favorable orientation that leads to its invisibility, but rather heating/cooling.

2017-08-17T12:30:09 --> 2017-08-17T17:20:09
A second CME eruption ~2 hours after the first one, originating from the back side of the sun (i.e. source region still behind the visible hemisphere).

2017-08-16T23:00:09 --> 2017-08-17T12:00:09
A low coronal signature of a CME "bubble" seen at the east limb. The source region is yet to be brought into view by the rotation of the sun.

2017-08-16T23:00:09 --> 2017-08-18T04:30:09
A solar prominence (i.e. a filament seen at the solar limb) rises and eventually erupts. There is a possibility for a CME event for this eruption.

2017-08-15T07:10:09 --> 2017-08-16T05:30:09
A large coronal hole extending from the north pole towards mid latitudes. Note the predominantly unipolar field distribution (green color)

2017-08-13T21:20:09 --> 2017-08-14T13:20:09
Three consecutive eruptions spaced apart by ~2 hours each in an AR that the solar rotation brings it to the visible hemisphere of the sun. It is not clear whether these eruptions were CMEs (lack of real time data at the time of this event annotation).

2017-08-12T14:10:09 --> 2017-08-14T13:20:09
A coronal hole of predominantly positive polarity that seems to extend all the way to the pole; effectively making it an extension of the polar coronal hole. The spread of the coronal hole suggests that it is created by the decay of the trailing polarity of an active region.

2017-08-10T00:00:09 --> 2017-08-11T09:50:09
A large coronal hole of predominantly negative polarity (red magnetic field contours). This coronal hole seems to be disrupted by some positive polarity elements (green) in the middle of its area - this makes the field lines to close with nearby negative patches (pink composite of 211A, 193A and 171A channel) and thus disrupt its area of open field lines.
