Coronal rain over AR 11996 precedes a GOES C4.1 class flare. Both 1330 Å and 1400 Å display the coronal rain and flare. The coronal rain's evolution is similar in both images. Initially, the coronal rain decreases in intensity, however, the coronal rain intensifies approximately a half hour before the flare triggers. The coronal rain intensification increases the coronal rain's footprint on the image and the number of arches (~1 to ~5).

2014-08-04T21:53:04 --> 2014-08-04T22:26:55

IRIS observes a GOES C1.0 flare in AR 12132 (visible in 1330 Å and 2796 Å). The flare forms an sigmoidal pattern between two filaments and crosses the slit. The spectrum shows redshifted emission in common lines (e.g. C II, Si IV, and Mg II h/k).

2014-08-03T06:11:36 --> 2014-08-03T06:40:26

IRIS observes a GOES C1.1 class flare in AR 12132 (visible in 1330 Å and 2796 Å). The flare forms three ribbons, which are connected via an absorption features in 2796 Å and emission in 1330 Å. The ribbons follow the contour of nearby coronal holes and filaments. During the flare, the slit crosses the event showing a spectrum with redshifted emission features (e.g., C II, Si IV, and Mg II h/k).

2014-08-01T06:47:27 --> 2014-08-01T06:54:00

IRIS observes a low intensity flare (no GOES classification). The flare originates on a warm intrusion inside a coronal hole in the image's center. Perhaps due to the flares the location, two horseshoe shaped bright regions create the flare. The flare's spectrum shows a brightening and broadening of common lines (e.g., Si IV and C II).

2014-07-30T02:41:20 --> 2014-07-30T02:52:50

AR 12121 produces a low intensity flare along a coronal filament (primarily visible in 1330 Å). The flare forms two ribbons, one at the base of the filament (center of the image) and another on the side of the filament (top of the image). The flare on the side of the filament creates coronal rain, which extends off the image's edge.

2014-07-30T00:23:53 --> 2014-07-30T00:59:08

IRIS captures a GOES class C1.3 flare in AR 12125 (visible in 1330 Å and 2796 Å). The flare starts as a small bright ribbon slightly right of center. The ribbon remains bright for a few frames until a bright region emerges to its left. Soon after the bright region emerges the ribbon quickly expands to the left. Once the ribbon ceases moving left, the flare expands to the right. The expansion registers as blueshifted and redshifted emission in common lines (e.g., Mg II h/k).

2014-08-01T17:54:59 --> 2014-08-01T18:54:29

IRIS observes a GOES class M1.5 flare, which is visible in 1330, 1400, and 2796 Å. The flare originates in two ribbons near the image's center. After formation, the ribbons move away from each other and decrease in intensity. The top ribbon stalls over a coronal hole and leaves behind a heated filament.

2014-08-04T15:37:41 --> 2014-08-04T15:47:54

IRIS in coordination with SUMER observes an unclassified flare in the image's upper right (marked). The flare forms via two roughly circular bright regions near the edge of a filament. Another flare forms later in the observation in the bottom eighth of the image and crosses the slit. However, most of the flare is outside the image. This flare creates a coronal rain, which extends to the position of the marked flare.

2014-08-03T14:44:31 --> 2014-08-03T15:06:52

A series of low intensity flares (no GOES classification) arise during a coordinated observation with SUMER. The flares (visible in 1400 Å and 2796 Å) primarily occur on the boundary of three nearby coronal holes located slightly left of center. The brightest, most interesting flare (marked) weaves around the three coronal holes. The slit captures a brightening region associated with this flare.

2014-08-02T07:53:37 --> 2014-08-02T08:17:34

IRIS (in coordination with SUMER) observes two low intensity flares (the first, more intense flare is marked) in the image's top left corner. Later coronal rain develops over regions where the low flares occurred. An unclassified, off image flare occurring at 09:45 likely initiates the rain. The coronal rain crosses the slit, however, the spectroscopic observations do not show any interesting features.

All observed wavelengths (1330, 1400, and 2796 Å) display sunspot oscillations in a coordinated observation with BBSO. The oscillations are best visible at 2796 Å and do not cross the slit.

2014-07-29T15:34:43 --> 2014-07-29T15:55:48

A small flare, best visible at 1330 Å but also visible at 2796 Å, occurs during a coordinated observation with VTT/DST. The flare forms a V shape and its vertex crosses the slit. The flare's intensity saturates and broadens the C II and Si IV spectral lines.

2014-05-09T02:20:37 --> 2014-05-09T02:53:54

An unclassified flare on the limb dominates the image of AR 12047 (encompassing the image's entire bottom half). As such, the slit captures the event. The spectral lines oscillate from redshifted to blueshifted in a sinusoidal pattern. The oscillation pattern's wavelength increases as time since the flare increases. As such, the spectrum initially shows one and a half oscillation wavelengths, but decays to less than a wavelength in two frames.

2014-05-08T10:50:44 --> 2014-05-08T15:12:25

An unclassified flare in AR 12060 initiates a down pour of coronal rain. The flare begins by ejecting material into the corona, but the jet subsides approximately 20 frames after maximum extent. Once the material reaches the corona, the corona rapidly responds by creating a network of coronal rain arches. The coronal rain event is short lived, like the jet. Still, the active area, which produced the jet, remains bright for most of the observation and is covered by the slit. When the active area is bright the spectrum shows an increase in emission features (~ a factor of two) and line broadening.

2014-05-12T03:12:24 --> 2014-05-12T03:27:40

IRIS observes part of a GOES C1.3 flare in the image's bottom left. The flare does not cross the slit, however, AR 12058 also creates a secondary low intensity flare (unclassified in GOES). The secondary flare does cross the slit.

2014-05-11T17:07:58 --> 2014-05-11T17:26:30

IRIS observes a GOES C3.1 Flare in AR 12056. The flare originates on either side of a coronal hole in the image's bottom left. In addition, a sunspot on the bottom right shows oscillations in 1330 Å and 2796 Å.

2014-05-10T14:55:52 --> 2014-05-10T15:15:03

A low intensity (no GOES classification) flare encompasses most of the image's upper left. The flare originates from two separate brightening regions, which eventually connect and produce a sigmoid like flare. In addition, the sunspot in the lower right shows two origins for the oscillations, which creates an interference pattern in the oscillations.

2014-05-10T02:28:29 --> 2014-05-10T03:50:08

All observed wavelengths (1330, 1400, and 2796 Å) display sunspots oscillations. The oscillations are most obvious in 2796 Å, however, 2796 Å's oscillations appear more chaotic than the oscillations in 1330 Å and 1400 Å. The observation also captures two small flares. One flare is a simple filament, while the second more intense flare creates a V shape.

AR 12055 shows a low intensity flare and a series of brightenings around a coronal hole. Both events broaden spectral lines lines like C II and Si IV and increase the continuum flux.

A region crossing slit erupts in three flare events. The flares' intensity is similar for all three eruptions in AR 12051. After each small flare, the coronal rain intensifies.
