GEOMAGNETIC ACTIVITY: A sharp gust of solar wind hit Earth's magnetic field at the end of the UT day on Oct. 21st, sparking a mild geomagnetic storm and Northern Lights around the Arctic Circle. Images: from Steve Milner of Fort St. John, BC, Canada; from Whitham D. Reeve of Anchorage, Alaska;

GEOMAGNETIC ACTIVITY: High-latitude sky watchers should be alert for Northern Lights. A sharp gust of solar wind hit Earth on Oct. 21st, and the Arctic Circle is still ringing with geomagnetic activity. "[We had a] stunning display of active auroras last night," reports Thomas Hagen, who sends this picture from Troms?, Norway:

"The entire sky turned green and stayed green for much of the night," adds Fredrik Broms of Kval?ya, Norway.
The solar wind gust that sparked the display is interesting because it likely originated with a spotless explosion in the Sun's southern hemisphere on Oct. 17th: movie. The blast hurled a faint coronal mass ejection (CME) toward Earth. Normally, CMEs reach Earth in only 2 or 3 days, but this one took a leisurely 4 days to cross the Sun-Earth divide. Why so long? Since solar minimum began in ~2007, solar physicists have noticed that CMEs have been moving in slow motion. They take a long time to get here, and they don't hit very hard when they arrive. Nevertheless, this one managed to spark some nice auroras.

NOT-SO-BLANK SUN: Today, the sunspot number is zero, which means the sun is blank, right? Wrong. This morning, NASA's STEREO-A spacecraft photographed sunspot 1029 seething with activity over the sun's western horizon:


Photo credit: STEREO Extreme Ultra Violet Telescope (195 A)

This impressive sunspot, which rotated over the sun's western limb three days ago, does not add to the sunspot number because it is no longer visible from Earth. Astronomers only count spots that are on the Earth-facing side of the sun. That's how it's been done since Rudolph Wolf invented the sunspot number in 1848. In those days, only one side of the sun was visible from Earth, so the tradition was established.

Now, however, for the first time in the history of astronomy, NASA's twin STEREO spacecraft are seeing over the sun's horizon, tracking sunspots that officially "don't count." The two spacecraft are moving toward opposite sides of the sun, and by February 2011 the entire sun will be under their watchful eyes. Perhaps it is time to start thinking about a "whole sun" sunspot number. As today's image shows, the sun is not always as blank as it appears to be.

Updated 2009 Nov 03 2201 UTC

Joint USAF/NOAA Report of Solar and Geophysical Activity

SDF Number 307 Issued at 2200Z on 03 Nov 2009

Analysis of Solar Active Regions and Activity from 02/2100Z to 03/2100Z: Solar activity was very low. The SOHO/LASCO imagery observed a slow coronal mass ejection (CME) off the southwest limb at 0501 UTC on 31 October. The CME appears to be earth directed with a plane-of sky speed of 380 km/s.

Solar Activity Forecast: Solar activity is expected to be low.

Geophysical Activity Summary 02/2100Z to 03/2100Z: Geomagnetic field was quiet.

Geophysical Activity Forecast: The geomagnetic field is expected to be quiet on day 1 (4 November). Unsettled conditions are expected on day 2 (5 November) due to possible effects from the CME observed on 31 October. Quiet levels are expected to return on day 3 (6 November).

Update - C-Class flare activity continues as a C3.7 flare took place 13:00 UTC Wednesday.

The largest Solar Flare of Cycle 24 thus far took place early Wednesday morning. It registered C5.3 on the flare scale. It is small in comparison to flares at solar max, however it is a good sign nonetheless. Click HERE for a movie of the flare.

A CME was associated with the C5.3 flare and an image is below. This may possibly produce Aurora by Friday when the CME arrives.

Sunspot 1035 is an impressive sunspot cluster consisting of around 20 spots. There will remain a chance for B-Class and perhaps more C-Class flares.

The solar flux reached 82 on Tuesday. The sunspot number of 38 is a new Cycle 24 record.

SIGNS OF LIFE ON THE SUN: 2009 is ending with a flurry of sunspots. So far this month, the visible disk of the sun has had spots 67% of the time, a sharp increase compared to the annual average. Furthermore, all six of December's sunspot groups have been members of new Solar Cycle 24. These numbers could herald the sun's awakening from the deepest solar minimum in nearly a century and a livelier sun in 2010.

Solar Update - Sunspot 1040 remains a fairly large sunspot group and there remains slight chance for an M-Class flare. The Solar X-Ray Flux background levels are in the B-Class territory and holding steady.

The solar flux reached a daily max of 90.8 on Monday and ended with an average of 89 which is a new record for Cycle 24.

Geophysical Activity Summary 10/2100Z to 11/2100Z: The geomagnetic field was quiet to unsettled. Solar wind observations from the ACE spacecraft indicated the onset of a co-rotating interaction region around 11/0844Z. Solar wind velocity increased from around 357 km/s to a max of 542 km/s at around 11/1540Z. The interplanetary magnetic field (IMF) activity showed an enhancement of total field of 14 nT, and the southern component of the IMF ranged between +10 nT and -9 nT.

Geophysical Activity Forecast: The geomagnetic field is expected to be quiet, with isolated unsettled levels for the next two days (12-13 January) due to a coronal hole high-speed stream. Quiet levels are expected on day three (14 January).

C-Flare - At 13:20 UTC a small C1.1 solar flare took place.

Solar Update - Sunspot 1040 remains a fairly large sunspot group and there remains slight chance for an M-Class flare. The Solar X-Ray Flux background levels are in the B-Class territory and holding steady.

The solar flux reached a daily max of 95.4 on Tuesday and ended with an average of 93 which is yet another new record for Cycle 24.

Analysis of Solar Active Regions and Activity from 11/2100Z to 12/2100Z: Solar activity was low. Region 1040 (N28W04) produced a C1.1 flare at 1320Z along with numerous B-class flares. Region 1040 showed little change in areal coverage (300 millionths) and was classified as an Eao-beta group with 25 spots.

Solar Activity Forecast: Solar activity is expected to be very low to low. There is a slight chance Region 1040 could produce an isolated M-class flare.

SOLAR FLARES: Today, Jan. 19th at 1340 UT, Earth-orbiting satellites detected the strongest solar flare in almost two years. The M2-class eruption came from old sunspot 1039, currently located behind the sun's eastern limb. NASA's STEREO-B spacecraft recorded this extreme ultraviolet movie of the blast:
Изображение
Considering the fact that the sunspot is not even visible from Earth, the flare was probably much stronger than its M2 classification would suggest. This active region has produced at least three significant eruptions since Jan. 17th (including this notable flare) and it is showing no signs of cooling off.

At the moment only STEREO-B, stationed over the east limb, can monitor the active region directly. Soon, this will change. The sun's rotation is turning sunspot 1039 toward Earth and it should emerge for direct viewing within the next 48 hours. Readers with solar telescopes are encouraged to monitor the east limb for developments.

Man, a bigger eruption can put all our global communications out of order and fry all the electronics in satellites. That global blackout can give an opportunity for terrorists to strike major targets while the government is "blind". It can lead to wars. It can also destroy the ozone layer and penetrate the Earth's magnetic field and rise global temperatures... Let's keep our fingers crossed that no more powerful eruptions will occur :(

In this day M2.3 class flare continue vith multiple activity and luminance ..
This M-class add SWX . solar weather .. a minor storm R1 - value changed to : 10-5W/m?

Any Explosions around this new sunspot (old Sunspot 1039) may not yet be earth directed because of its position on the eastern limb. It will rotate into view within the next few days.

Yesterday's M2-class solar flare bathed Earth's upper atmosphere in X-rays and caused a wave of ionization to sweep over Europe. This actually improved the propagation of low-frequency radio signals, which use the ionosphere as a reflector to skip over the horizon. A SID monitor operated by Rudolf Slosiar in Bojnice, Slovakia, recorded the surge in signal strength:

Radio blackouts reaching the R1 level are expected.
