2016-04-18T00:00:06 --> 2016-04-18T06:00:06

M6.7 flare associated with a large global coronal wave covering the entire western hemisphere. Which likely triggered the small prominence eruption in the same neighborhood on the limb, as reported yesterday.

In the spectra, there are peculiar Mg profiles at the very bottom of the slit. It looks like loop parallel to the slit.\nThere are also several small brightenings. See 16:47UT near slit center.

2016-04-17T21:00:06 --> 2016-04-18T04:00:06

A small prominence erupted on NW limb at about 01:40 (Apr 18). Note this is preceded by another eruption, possibly a CME (no prominence involved) at 23:00 on Apr 17, in the same neighborhood. It's possible that this early eruption destablized the prominence and led to its eruption.

2016-04-13T23:25:06 --> 2016-04-14T02:20:06

Some energetic event west of the leading polarity spot of AR 12529 launches chromospheric (304) material into high lying AR loops.

2016-04-10T10:15:06 --> 2016-04-10T12:00:06

This filament eruption occurs about two hours following an eruption from AR 12529. The two are possibly sympathetic events.

2016-04-10T05:00:06 --> 2016-04-10T12:00:06

This eruption is possibly due to the formation of a flux rope in the corona. There is no sign of a filament destabilization from the source region. Within two hours of this eruption there is a nearby filament eruption. This filament is originally located northwest of AR 12539. It is possibly that the two are sympathetic events.

NOAA SWPC C1.5 flare 5:49-Peak9:34-13:04 UT. IRIS is observing over the flaring region. The flare appears to be bright in EUV and X-ray and not particularly bright in UV and optical wavelengths. Multiple radio events reported during this long-duration event.

NOAA SWPC event 9860 20:59-Peak21:01-21:04 flare with faint sub-flare in H-alpha and a minor type CTM (broadband, long-lived, dekametric continuum) radio burst. \n\nCoronal rain is visible as a bright ribbon-like flow located in a horizontal strip, left to the slit in the vertical center of the field of view. These flows appear to cross the slit. Coronal rain is easiest to see between 21:09 - 21:19 UT. See also, AIA 304.

NOAA SWPC event #9830: 18:40-Peak18:44-18:46 C1.5 flare and dark surge faint sub-flare in H-alpha. NOAA SWPC event #9850: 20:29-Peak20:34-20:43 C1.5 flare and faint sub-flare with several eruptive centers in H-alpha. NOAA SWPC event #9860 20:59-Peak21:01-21:04 flare with faint sub-flare in H-alpha and a minor type CTM (broadband, long-lived, dekametric continuum) radio burst. NOAA SWPC event #9890 22:50-Peak22:55-2305 C1.8 flare and faint sub-flare with several eruptive centers in H-alpha; type CTM radio burst was also reported.\nLong-dark ribbons are visible in AIA 304 that could be associated with coronal rain. These long, dark ribbons possibly cross the IRIS slit and may show up as absorption features in Mg II. Coronal rain is visible, just east of the slit in the 1330 SJI after some of the flares.
