2016-08-21T06:01:35 --> 2016-08-21T06:48:38
An AR prominence on west limb has a growing loop extending over time toward the south.

Another minor flare B1.x (on GOES) around 18:47 from AR 12578 during this BBSO coordination under HOP 320. This flare is stronger than the previous on at 17:23 in the same region and clearly shows two ribbons. One ribbon under the slit.

Minor flare B1.x (on GOES) around 17:23 from AR 12578 during this BBSO coordination under HOP 320. Elongated flare ribbons under the slit.

The filament apparently lay above three active regions. The eruption was noted only in 304 A images. No CME in LASCO.

Minor flare (< B) in AR 12578 during this HOP 306 (IRIS only) scan. The AR filament at the location of the flare also gradually faded over hours toward the end of this obs.

On-disk coronal rain into sunspot captured in this AR 12578, HOP 322 Fuxian Lake/Hida coordination. Slit on the rain in the later portion of the raster scan (right-hand side).

Around 18:15 UT, Aug 19, dynamic flows with intense brightening along curved paths with sharp turns. The slit only captured the eastern (left-hand side) end of the flows.

2016-08-19T08:28:34 --> 2016-08-19T10:19:04
B1 flare (two-ribbon) straddling the boundary between AR 12574/12577. This is first flare caught by IRIS this week so far. Slit covered most of the flaring region and at least one ribbon. There was also many UV bursts/brightening within this obs. near the flare site.

2016-08-19T04:37:47 --> 2016-08-19T06:38:24
A nice AR prominence on NW limb showing oscillating horizontal threads that are almost parallel to the slit. This would be a nice data set for studying wave propagation along the threads, with good slit coverage over a long distance range.

2016-08-18T18:53:36 --> 2016-08-18T20:16:40
UV burst to the left of the slit, and dynamic flows under the slit during the HOP 317 BBSO coordination of AR 12577

2016-08-18T08:12:07 --> 2016-08-18T11:14:42
AR prominence exhibited wavy horizontal threads, and some of them give a floating sense and travel upward. Roll=90, so the bottom of the slit was nicely located on the disk for best absolute wavelength calibration.

2016-08-18T06:39:17 --> 2016-08-18T07:21:01
UV burst occurred to the left of the northern sunspot in AR 12577 (during 400-step raster). The slit crossed it near the peak of the burst.

This AR prominence on NW limb displayed horizontal threads and flows, very much like this first reported by Okamoto with Hinode/SOT.

horizontal flows along low-lying loops over "sunspot". This was with BBSO coordination IHOP 317, on AR 12577

The same AR prominence on NW limb observed earlier today, exhibited horizontal flows (under slit), and possibly one to two bubbles (mostly not under slit).

A prominence on NW limb exhibited a possible prominence bubble - appearing as a circular dark hole (not under the slit). To the lower-right of the prominence, there was tumbling flow patterns (under slit), resembling plumes pushing up from below, as seen with Hinode/SOT (Berger et al. 2010, 2011). It's a very interesting event, although the IRIS coverage was brief.

1) Horizontal flows in low-lying loops over the sunspot (under slit)\n\n2) To the lower-right of the sunspot on the top, there were brightenings associated with a jet that shows a circular-shaped footpoints at times.

This observation shows a nice envelope which host a recurrent long and straight collimated jet. The jet shows strands.

Recurrent jet follows highly bended and twisted field lines. The jet is broad more similar to a surge which seems to drift from left to right.

This observation shows 2 main flares. The second is capture by the slit. The first one shows a activated filament.
