The largest flare, M-class, took place in the observations of AR 12824, although it was at the edge of the FOV. Several small flares and jets occurred around this sunspot, some of which were covered by the IRIS slit.

2021-05-22T12:38:25 --> 2021-05-22T16:50:51
AR 12824 becomes active. More flares, jets, and explosive events take place frequently. The IRIS slit is on the penumbra, and covers the footpoints of numerous jets.

In the early phase of activation at AR 12824, a small explosive event took place in the penumbra. The GOES class is B.

IRIS observes full lifecycle of bright point, that emerges and then fades.

2021-05-13T17:20:40 --> 2021-05-13T22:54:24
Possible small flare/ribbon brightening to SW of sunspot that crosses slit in one place. Other eruptive events to the SE of the FOV.

2021-05-08T18:42:08 --> 2021-05-08T19:12:41
Both ribbons of this C8.6 class flare were observed by the IRIS slit on May 8th 2021.

2021-05-07T18:50:33 --> 2021-05-07T19:34:15
The ribbons and loops of this M-class flare were partially observed by IRIS on May 7th.

This eruption resulted in a slow but wide CME observed by LASCO.

2021-05-09T09:30:01 --> 2021-05-09T11:30:01
This filament was sitting neaxt to a plage region. The eruption is clearly traceable with aid by spreading ribbons at its base.

2021-05-05T14:07:46 --> 2021-05-05T17:53:10
Small-scale eruption accompanied by a coronal dimming at flux cancelation site.

2021-05-06T01:28:30 --> 2021-05-06T22:00:45
There is an emergence of a small bipole. Later, the one foot (negative flux patch) of the newly-emerged bipole cancels with the neighboring positive flux patch.

Evolution of a quiescent prominence on north-west limb of the Sun.

2021-05-04T10:55:17 --> 2021-05-04T15:05:41
Jets resulted from the eruption of a small-scale filament (known as minifilaments).

AR 12818 had produced some eruptions before it rotated on to the visible side. It was already well into decay, when another region emerged to its west (AR 12820). Then to the west od AR 12820, another region AR 12821 emerged.

This high-latitude eruption was slow, but on a large scale. Images in 171 channel indicate structures reminiscent of a flux rope. The eruption resulted in a decent CME ( https://cdaw.gsfc.nasa.gov/images/soho/lasco_ql/2021/04/29/20210429_204807_lasc2rdf_ql.png ).

2021-04-28T07:44:58 --> 2021-04-28T09:00:10
The initial brightening took place in AR 12820 (east), but subsequent brightening seemed to be around AR 12821, perhaps induced by the initial eruption to west. The subsequent eruption was mostly northward from AR 12821.
