2017-07-03T15:30:01 --> 2017-07-03T18:00:01

More energetic version of the B1.3 flare on 2 July 2017. Cool prominence matrial is more clearly seen. However, supra-arcade downflows, often seen in eruptive flares, seem to be missing.

This slow eruption or disappearance of a large-scale structure is seen preferentially in 171 A images. It may be responsible for an outflow in LASCO images, which may not be classified as a CME.

2017-07-02T11:50:25 --> 2017-07-02T14:20:25

These running difference images reveal the coronal wave more clearly. It is also easier to find the erupting filament. The wave is more pronounced in the counterclockwise direction. It seems to produce a secondary wave as it propagates into large-scale structures.

This eruption was similar to the earlier one (around 00:30 UT), but the erupting filament was more clearly seen, accompanying coronal dimming.

This minor eruption occurred in the northwestern periphery of AR 12664. It looks like a confined eruption.

A small-scale flux emergence region was observed with increased coronal activity.

IRIS observes a small jet in AR 12662. The jet produces two faint spires during the observation. Unfortunately, the spectroscopic slit misses both jet activations.

IRIS observes a microflare in AR 12663 with a five second cadence in coordination with GREGOR. The flare begins with at least two primary bright loops well separated in projection. Then the projected distance between the two loops shrink until they appear to connect. During the apparent connection, the flare reaches its maximum intensity. The spectroscopic slit scans the event and shows an eruption of cool material (blue shifted absorption) in the Mg II line core.

IRIS observes AR 12663 in coordination with BBSO. During the coordinated observation, the region produces a few faint UV bursts between the slit. However, the slit does not capture the UV bursts. Furthermore, a few more intense UV bursts and an unclassified flare occurred in the image's bottom right.

2017-06-17T17:29:05 --> 2017-06-17T21:24:56

IRIS observes a series of UV bursts in AR 12663. The observed UV bursts occur west of the trailing sunspot in AR 12663, during a coordinated observation with BBSO. While many bursts are just east of the slit, a few times the slit captures the burst. As such, the IRIS spectra show broad emission features. The IRIS spectra also show interesting cool plasma flows in Mg II k and h. The Mg II SJI shows the flows may be related to the UV bursts.

IRIS observes a two ribbon microflare in AR 12662. The microflare's ribbons are on the east and west boundaries of AR 12662's lone sunspot.

IRIS observes coronal rain over AR 12661. Unlike most coronal rain observations the material during the observation shows a non radial flow in its decent. The combination of projected motion and the slit coverage may make an interesting observation of cool plasma.

2017-06-14T04:22:29 --> 2017-06-14T05:23:14

IRIS observes a decaying jet in AR 12661. The observation shows a broad spire in the beginning, which fades during the lone raster scan. The slit captures the jet's end. In addition, the observation captures coronial rain north of the AR and a prominence south of the AR.

IRIS observes a jet in AR 12661, while AR 12661 is on the limb. The jet steadily increases intensity and spews more material throughout the observation. When the jet's intensity peaks the slit perpendicularly scans the jet.

IRIS observed coronal rain over AR 12661, during a 90 degreed rolled observation. The slit scans the height of a few coronal rain streams, which may give three dimensional coronal rain stream velocities.
