Flares observed by SECCHI EUVI on board the STEREO mission (up to October 2010)

The following table gives links to movies and plots of the individual flares observed by EUVI. Just click the start time. You will see something like this, which explains what are available.

The first four columns do not need explanation. Some events are actually not flares (N-FL), but included in the table for specific reasons. The source region usually corresponds to an active region with a number assigned by NOAA. But it may an active region but without NOAA number (U-AR) or outside active regions (N-AR). The last column will be populated later on.

Here is the list of criteria to assign a number to the next five columns.

  • Dimming (1-5) - from macro pixels that dimmed by more than 10%

    1: 0-5 such macro pixels, 2: 5-10 such macro pixels, 3: >10 such macro pixels in one wavelength, 4: >10 such macro pixels in two wavelengths, 5: >10 such macro pixels in three wavelengths

  • Eruption (1-4) - from visual inspection of images

    1: Nothing, 2: Confined ejection, 3: Jet-like ejection not confined, 4: Large (CME-like) ejection not confined

  • Wave (1-4) - from running difference of 195 A images

    1: Nothing, 2: Marginal, 3: Small scale (less than 1/2 Rsun), 4: Large scale

  • CME (1-5) - from LASCO and COR1/2 images

    0: No coronagraph data (LASCO or STEREO), 1: No noticeable outflow, 2: Outflow that disppears within 3 Rsun, 3: Narrow CME or jet (e.g., narrower than 20 deg), 4. CME, detectable up to 10 Rsun, 5. CME, detectable to > 10 Rsun

  • Type III burst (1-4) - from Wind/WAVES spectra

    1: Nothing, 2: Delayed with respect to the impulsive phase, 3: Weak, but appears to be during the impulsive phase, 4: Clear, impulsive phase.

    2007/05/14 13:16 A8.0 956 N04E80 1 1 1 1 1 The association with the 72 degree wide LASCO CME is questionable. Light dimming seen around the flare region but the depth does not reach the threshold of 10%.

    2007/05/30 13:49 C2.0 960 S08E115 1 1 1 3 1 The C-class flare seems to be from behind the limb, likely to be AR 960. It is preceded by smaller activities in AR 958.
    2007/05/31 12:43 C1.1 960 S09E102 1 1 1 1 1
    2007/06/01 06:46 M1.0 960 S08E95 3 1 1 1 1 The CME observed around the same time may not be directly associated with the flare

    2007/06/01 21:40 M2.1 960 S08E82 1 1 1 1 1 This M-class flare is confined. The following C-class flare, at nearly the same location, seems to be responsible for the CME.
    2007/06/01 22:17 C2.8 960 S08E82 2 4 1 5 1 The large-scale loops that erupted was offset to south from the flare center by ~15 degrees.

    2007/06/03 02:06 M7.0 960 S07E68 1 1 1 2 1 Two M-class flares occurred in succession, neither of which was associated with a CME except for an outflow up to ~2 Rsun
    2007/06/03 06:36 M4.5 960 S07E65 1 1 1 1 1 LASCO recorded a narrow CME up to < 5 Rsun, but COR1 data show this was associated with a B-class flare that preceded the M4.5 flare, hence the rating of "1"

    2009/10/27 13:07 B8.3 1029 N16W40 1 1 1 1 1 The interval contains several more B-class flares mostly confined. Dimming is deep and extended over the 9 hour period, but it is not correlaterd with CMEs and flares.

    2010/02/06 15:25 C3.4 1045 N24E20 1 1 1 1 1 The B-class event on the decay of this flare may be associated with a minor CME or outflow starting ~16:35.

    2010/02/06 21:31 M1.3 1045 N22E12 1 4 1 4 2 The type III burst corresponds to the second peak, in which the westward ejection associated with the first peak moves to southwest.
    2010/02/06 22:27 C2.2 1045 N23E13 1 3 1 1 4 Location from EUVI-A and EUVI-B. May not be separable from the M1.3 flare.
    2010/02/06 22:45 C2.7 1045 N23E13 1 1 1 1 1 May not be separable from the M1.3 and C2.2 flares.
    2010/02/07 02:20 M6.4 1045 N21E11 2 4 4 5 4 Quick (<~1 hour) recovery from dimming. This seems to be a halo from Earth view.

    2010/02/07 21:09 C4.2 1045 N21E00 1 3 1 3 4 The next two are not separable (21:31 C4.2, 22:28 C1.0). Narrow CME(s) associated with jets. Not enough time resolution to see details.

    2010/02/10 06:11 B8.6 1045 N21W25 1 1 1 1 1 This and a bunch of other B-class flares (05:56 B3.4, 07:03 B4.8, 07:16 B7.7) were not eruptive, but during the last one, a sigmoid region to the west of AR 1045 erupted.
    2010/02/10 14:58 C1.2 1045 N22W34 1 1 1 1 1 Not separable from the C3.7 flare at 15:10 UT. These two C-class flares in AR1045 were not eruptive, but an eruption occurred in AR 1046, starting ~16:00 UT. This one was associated with a CME, and possibly with a type III burst.
    2010/02/10 22:03 B9.5 1046 N23E31 1 4 2 3 4 Eruption/CME better seen on STA (flare slightly behind the limb).
    2010/02/11 05:57 B6.5 1046 N23E27 2 3 1 4 4 Eruption better seen on STA (CME hard to see because of an earlier event).
    2010/02/11 14:10 N-FL 1045 N20W55 3 3 1 1 4 West of AR1045. STA only. The B5.2 flare at 15:08 was from AR 1046 and not observed.

    2010/02/12 17:52 M1.1 1045 N25W53 1 2 1 1 1 The flare itself looks like a failed eruption, not seen ~30 degrees behind the west limb from STB. Before the flare, a minor eruption is seen to the west of AR 1045, a smilar pattern to the event at 2010/02/11 14:10.
    2010/02/12 20:46 C1.3 1046 N25E05 1 1 1 1 1
    2010/02/12 22:33 C3.0 1045 N25W55 3 4 1 4 4 This flare starts later than a gradual flare (~22:00), which is associated with the CME and related signatures.
    2010/02/13 07:46 C4.3 1048 N21E88 1 1 1 1 1 Many type III bursts in the time range, but none corresponds to this flare.
    2010/02/13 12:28 C9.6 1048 N21E87 3 1 1 1 1 The flare is not eruptive, but a minor eruption is seen ~90 degs west of the flare (see full disk-B movie), which was seen over the limb by STA (but the flare region is too much behind the east limb to be seen).

    2010/03/04 16:03 C2.2 1052 S16W66 1 1 1 1 1 This one is boring, but the B6.0 flare (13:28 UT, S16W59) in the same region was eruptive with an EUV wave.

    2010/03/30 18:00 N-FL N-AR N27E70 3 4 1 5 1 This event was used in the first poster of SDO/AIA, showing a prominence eruption, which is also seen in STA 304 A images.
