2023-04-27T21:24:51 --> 2023-04-27T21:59:35
A small compact flare around C-class level is observed under the IRIS slit.

2023-04-27T15:50:07 --> 2023-04-27T16:39:43
A C1.8 flare is observed close to the edge of the IRIS SJI field of view. Part of the ribbons are under the IRIS slit.

2023-04-27T11:42:32 --> 2023-04-27T13:21:28
IRIS missed the impulsive phase and peak of an M1.8 flare in AR 13288, but observed the later phases during which a lot of flaring activity is still observed. Part of the flare ribbons are under the IRIS slit.

2023-04-27T11:09:22 --> 2023-04-27T11:32:01
IRIS observed this flare around the same time as an M1.8 flare occurred in AR 13288. (It might be a sympathetic event). The scan proceeds at an ideal time and pace catching a large portion of the ribbons as well as the hot loops visible in the IRIS FeXXI spectral line.

2023-04-26T19:06:50 --> 2023-04-26T20:33:26
This IRIS observations catches a lot of small scale activity in AR 13285 while its magnetic field evolves rapidly. There is significant flux emergence and cancelation, UV bursts, filaments, flows, small flares -- not all caught under the slit.

2023-04-26T14:02:41 --> 2023-04-26T15:38:57
A UV burst is under the IRIS slit in this sit-and-stare observation which provides a very nice high cadence (<10s) view of the evolution of its spectral properties.

2023-04-26T09:28:28 --> 2023-04-26T11:02:12
Nice coronal rain dataset where IRIS catches spectra of the coronal rain out to relatively large heights and with nice cadence (<10s) due to the sit-and-stare nature of the observation.

2023-04-25T07:14:45 --> 2023-04-25T07:44:44
Small flare ribbon visible in SJI but not under the slit. The hot loops (visible in AIA 94) are short-lived (< 10 min)

2023-05-05T19:32:30 --> 2023-05-05T20:58:25
Plasma jet off to the bottom right of the FOV. Ejected plasma reaches an apex in its trajectory, then falls back to the surface.

2023-05-04T09:58:46 --> 2023-05-04T10:21:53
Very active run, with many brightenings and interesting plasma flows throughout the observation. Likely unclassified non-GOES flare with ribbons crossing the slit and plasma ejections occurs towards beginning of observation (t~10:05).

2023-05-04T08:27:16 --> 2023-05-04T09:27:55
Non-GOES flaring activity caught in FOV to the left of slit. Interesting plasma flows caught at end of observing run, possibly over slit.

2023-05-03T18:11:30 --> 2023-05-03T18:31:30
C3.0 flare produced from AR13293, followed by two lesser C-class flares. Evolution captured under slit.

2023-05-03T12:58:24 --> 2023-05-03T14:13:44
M2.2 flare produced from AR13293. \nFull evolution captured under slit. \nIncredible pre-flare and eruption dynamics captured via high-cadence SJI observations. \n\nSmaller C-class flares (C3.1, C1.9, C1.8) also fully captured in FOV and along slit following the M2.2 event. \n\nLingering impulsive activity develops along slit for much of the observation\u2019s duration, along with interesting plasma flows.

2023-05-03T08:28:43 --> 2023-05-03T11:07:16
Three M-class flares produced in rapid succession from AR13293. Chronologically: M4.2, M3.1, M7.2. Total lifetime of each flare --- pre-flare build-up, impulsive energy release, decay --- is captured under the slit for each flare. Localized, lingering activity following the M7.2 flare can also be seen along the slit. Ejected material and plasma flows can be seen in the SJI for each flare as well.

Non-GOES class flare w/ ribbon. Possible redshifts in spectral lines.

2023-05-02T14:33:10 --> 2023-05-02T17:02:45
SJI 2796 shows interesting oscillations/waves in the sunspot umbra. In addition, there are several brightenings along the slit that exhibit explosive behavior, including possible Fe XXI emission at the end of the observation.

2023-05-02T10:09:21 --> 2023-05-02T10:56:29
Small flare with ribbon over slit. Some of a larger C2.4 flare can be seen later in the bottom right of the FOV.

2023-05-02T05:36:48 --> 2023-05-02T06:12:01
Small, short duration flare in AR 13288. Flare simultaneous with another flare in AR 13293 --- possible sympathetic event. Not much spectral activity.
