There are currently three active regions on the sun capable of producing a major flare - good news for whole sun instruments. NOAA 0501 (N03W02) was the source of an M1.7 event at 11/19/04:06:00 UT and three C-class events. 0501 is still a beta-gamma-delta magnetic configuration with three deltas. NOAA 0507 (N10E68) is located in the area of old active region 0488. 0507 has a reversed polarity beta-gamma-delta magnetic configuration but so far after rotating over the NE limb, it has been mostly quiet. The return of super active region of X28 fame, NOAA 0486, is just now becoming visible on the SE limb at about S17. This region has produced two C-class events since producing the M4.5 event yesterday. It is too close to and beyond the SE limb to ascertain its magnetic complexity but it appears to be reversed polarity with a large area of positive polarity in the leading portion.

Three active regions have the potential to produce a major flare: Old super active region, NOAA 0486, is at and just beyond the SE limb at about S17. Old 0486 produced an M4.5 event today at 10:11 UT. NOAA 0501, N03E10 produced 3 interesting M-class events today (M1.8 at 01:39, an M3.2 at 07:52 and an M3.9 at 08:31 UT). 0501 maintains its complex beta-gamma-delta magnetic configuration. Old active region, NOAA 0488, is rotating over the NE limb at N10. 0488 is still too close to the limb to ascertain its magnetic configuration, but the leading sunspot is large and appears to have a beta-gamma-delta configuration.

The last paragraph of Alan Kiplinger's message regarding the recent solar activity got corrupted. Please also note that Don Neidig's affiliation is AFRL/VSBXS. Alan Kiplinger's e-mail address is kiplinge@sunwave.colorado.edu

The last paragraph should read as: There was a large westward coronal mass ejection (CME) associated with the X-28 flare on 04 Nov. This flare associated CME was proceeded by a halo CME. This halo CME was almost surely associated with active region 0484 which was on the back side of the sun. Another spectacular halo CME occured ~17:00 to 18:00 UT on Nov. 6. Region 0484 produced 2 X- and 16 M-class flares and is due to return ~ Nov. 12. Region 0488 is just beyond the west limb and it has produced X- and M-class flares. Thus, it is most likely that the show is not over.

For those of you with interests in the recent solar activity, Alan Kiplinger, Center for Integrated Plamsa Studies, U. of Colorado and NOAA/SEC, has provided us with his discription of this remarkable solar activity.

At approximately 19:29 UT on 04 Nov. 2003 the Sun began an eruption in NOAA region 0486 at S19W86 of the largest solar flare ever recorded in soft X-rays (see http://www.bbso.njit.edu for a movie of the flare obtained at the Big Bear Solar Observatory of the New Jersey Institute of Technology). By 19:44 UT, NOAA's GOES 12 satellite reached saturation at X-17.4 (1-8A) an remained saturated until 19:55 UT. In order to estimate the actural peak intensity, I compared this flare's behavior with earlier flares from the same region. The three prior X-class flares occurring on 02 and 03 Nov. had much slower rise and decay times when compared on log plots of intensity. However, the X-10 flare of Oct. 29 matched the rise and decay times of the 04 Nov. flare almost precisely over a 50 minute period spanning the peak. By superimposing the curves, I deduced that the flare reached X-28 (+/- 3, a conservative error estimate) at 19:47 UT. Independently, Dr. Rodney Viereck of NOAA/SEC fitted the rise and decay curves with polynomial and log-normal functions and arrived at peak flux values ranging from X-25 to X-31. Accordingly, NOAA/SEL has tagged this flare as an X-28 (estimated) which makes it the largest soft X-ray flare ever recorded. The coronagraph at Sacramento Peak Solar Observatory also recorded the most intense coronal emission that it has ever seen. Very fortunately, the region was located extremely close to the west limb; thus, it was not magnetically well connected to us and effects at Earth were not terribly dramatic or destructive.

Don Neidig (AFGL/PHL) at sacramento Peak Observatory reports that the ISOON H-alpha telescope recorded point brightenings that progressed to the south pole in association with the flare. Sara Martin (Helio Research) commented that the SOHO 175A images from EIT showed simultaneous darking of coronal hole areas at the south pole and darking of a north-south area (channel?) near the central meridian and just above the equator. This indicates that the region is globally connected.

The comparison X-10 flare of 29 Oct. from AR 0486 is equally interesting. Brian Dennis (NASA/GSFC) reports that the flare is, by far, the most intense gamma ray line flare observed by the Ramaty High Energy Solar Spectroscopic Imager (RHESSI). RHESSI missed the peak of the X-28 event. The X-10 flare also was well observed by ISOON. Don Neidig reports clear evidence for a Morton wave as observed in on-band and +/- 0.4A off band patrol images. The wave can be seen in the direct images but is best seen by subtracting the red minus blue off-bandimages. The wave proceeded from the region to the north-east with a cone angle of about 50 degrees. It was not just a single front, but a wave train (like a moving washboard) with about three or four waves. The speed was 1100 km/sec, wavelength 88000km, peroid 80s, and data indicate vertical amplitude changes of roughly 66 km. We interpret the wave train as a mechanical oscillation of chromospheric material due to compression from the Morton wave. Sara Martin also reports that there were simultaneous darkenings near the south pole as recorded by SOHO's EIT at 175A, thus confirming regional global connections.

There was a large westward coronal mass ejection (CME) associated with the X-28 flare on 04 Nov. This flare associated CME was proceeded by a halo CME occured ~17:00 to 18:00 UT on Nov. 06. Region 0484 produced 2 X- and 16 M-class flares and is due to return ~ Nov. 12. Region 0488 produced X- and M-class flares. Thus, it is most likely that the show is not over.

BBSO Solar Activity Warning 25-NOV-1998 21:37:57 UT
Dear Colleagues:

In order to serve the solar physics community better, Big Bear Solar Observatory (BBSO) has changed the way it reports solar activity. BearAlerts will no longer be issued by BBSO. The new program will have two components:

  1. At least once a day, BBSO provides Solar Activity Reports which are a survey of active regions. The reports are posted on http://www.bbso.njit.edu/, under the link "Solar Activity Reports". Please visit our web site. Griffith Observatory just noted us as "Astronomical Website of the Week" (http://www.GriffithObs.org/StarAward.html).
  2. When warranted, BBSO also issues a BBSO Solar Warning statement forecasting rapid development and/or energetic solar flares in individual sunspot groups. In addition to being posted on the above web page, the warnings are sent via electronic mail. If you are on the BBSO BearAlert list, you will continue to receive new BBSO Solar Warnings. If you wish your name to be added/deleted to the list, please send a message to activity@bbso.njit.edu, including your e-mail address, affiliation, and full name.

We note that while SOHO/MDI magnetograph observations were interrupted from June to October, 1998, the TRACE team requested that BBSO provide magnetograms to support its observations and issue an activity report every day to describe the status of each active region on the disk. We received very positive feedback on those reports, therefore we believe that the community will benefit from such reports and warnings.

If you have any comments about this new BBSO report/warning system, please send a message to activity@bbso.njit.edu.

Sincerely yours,

Phil Goode,
Director
Big Bear Solar Observatory
