2013-10-06T13:00:03 --> 2013-10-06T17:00:03
This may not look like a major eruption. It is associated with a modest C1.1 LDE. However, it is associated with the only halo CME during the interval that can be responsible for the moderate storm that started late on 8 October 2013 (KP=5). The CME is quite diffuse with the northern part being more visible in spite of the location of the eruption (AR 1859, a good number for a geoeffective event). There is no clear filament eruption in 304 A images.

2013-10-05T04:00:03 --> 2013-10-05T08:00:03
The eruptive signatures are clearly noted in AIA images even though the source region is estimated to be more than 30 degrees behind the limb. The event is associated with a type II radio burst (both metric and DH), and a halo CME. Based on the LASCO MVI files archived at NRL (no movies available at GSFC because of the goverment shutdown), the bright CME is first observed at 07:10 (at the heliocentric distance of 2.8-2.9 Rs and PA of 125 deg), and the linear speed is only about 630 km/s using five difference images.

2013-09-30T17:30:03 --> 2013-09-30T18:40:03
An interesting surge with part of it following a loop-shaped trajectory (likely guieded by coronal loops), and another part of it returning along the original path of ascent close to the local vertical.

2013-09-29T20:30:03 --> 2013-09-30T00:00:03
A large filament between two ARs erupts, producing nice two-ribbon brightenings. It does not seem to produce an EIT wave, probably because of its gradual (rather than impulsive) acceleration profile.

2013-09-29T10:40:03 --> 2013-09-29T12:10:03
A surge likely associated with a behind-the-limb eruption on the east limb. Note the wavy trajectory of the ejected material.

2013-09-29T00:00:03 --> 2013-09-29T02:50:03
A small eruption near the SE limb.

2013-09-29T00:00:03 --> 2013-09-30T00:00:03
A ploar-crown prominence slowly lifts off, the 171 loops and likely a coronal cavity erupted, leaving behind the 304 prominence material falling back.

2013-09-28T08:00:03 --> 2013-09-28T12:00:03
Two small and not-really-very exciting filament activations on/near the east limb are notable only for the fact they are nearly simultaneous. I leave open the question as to whether they are causally related.

2013-09-29T21:00:35 --> 2013-09-29T23:59:59
Someone asked the space weather forum if the Sun is dead, but this is the first major eruption in weeks. As expected, a halo CME is associated. LASCO saw its first sign at 22:12 UT. It is probably Earth-directed, and several heliospheric predictions will be made. The associated flare is C1.2.

2013-09-24T18:36:03 --> 2013-09-25T00:00:03
A quiet-Sun filament/prominence erupts over the NE limb, with prominent post-eruption emission following ribbon expansion.

QS prominence over the SE limb at high latitude erupts. View interrupted by Earth occultation.

Compact eruption from QS with coronal dimmings in adjacent QS corona.

Quiet-Sun filament eruption from the SW quadrant.

2013-09-22T18:00:03 --> 2013-09-22T19:20:03
The eruption is most clearly seen in 304 A images. The lack of obvious brightening (e.g., flare) suggests that this is energetically minor. No obvious CME is associated.
