THIS IS NO LAUGHING MATTER: There is a smiley face on the sun today. Take a look. Formed by holes in the sun's atmosphere, the cheerful mein is spewing a complex stream of solar wind toward Earth. First contact, with auroras, could occur on Oct. 28th or 29th. SpaceWeather.com

Everything remains at low levels, Only two B-class and two C-class flares. That was all. The largest event of the period was a C6.7 flare at 12:43 UTC from AR3133 (N25E58)

SOLAR CYCLE 25 ACTIVITY REPORT NOVEMBER 04

Another day of low seismic activity in which the AR3135 region, which was the most active in the past days, did not generate any flare. The turn this time was for AR3136 with two minor flares of which the largest was a C1.3 at 07:23 on November 03.

There are currently 5 numbered active regions on the solar disk: AR3131, AR3135, AR3136, AR3137 and  new Region AR3139

AR3139 located on the northeast (N28E47) is a group of sunspots with an area of 20MH and a beta magnetic configuration. NOAA forecasts 15% chance for M flares


All of today's sunspots have stable magnetic fields that pose almost no threat for strong solar flares

The total number of sunspots has decreased to 65 (15 of these are grouped into 5 active regions) NOAA forecast for the next 24h is 55% chance for C flares, 10% chance for M flares and 1% chance for X flares.

● Auroral Activity

The geomagnetic field has been at active to storm levels for the past 24 hours. Active geomagnetic conditions (Kp4) threshold reached at 08:59 UTC on November 03 Minor G1 geomagnetic storm (Kp5) threshold reached at 14:36 UTC The solar wind speed record reached a peak of 628.4 km/sec at 20:33 UTC. Geomagnetic storm subsided around 21:00 UTC The maximum planetary index Kp in the past 24h was Kp5

CHANCE OF STORMS TODAY: NOAA forecasters say there is a chance of G1-class geomagnetic storms on Nov. 4th and 5th as Earth continues to pass through a stream of fast-moving solar wind. The gaseous material is flowing from an equatorial hole in the sun's atmosphere. Yesterday, the same stream sparked spectacular pink auroras inside the Arctic Circle. SpaceWeather.com

Pink auroras are a sign of nitrogen. Most auroras are green--the color of oxygen atoms being struck by energetic particles 100 km to 300 km above Earth's surface. Pink appears when energetic particles from space descend lower than usual, striking nitrogen molecules at the 100 km level and below.

What happened? Just before Varik went out aurora hunting, a crack formed in Earth's magnetic field. Energetic particles rushed through the gap, penetrating deeply enough for pink. SpaceWeather.com

MYSTERIOUS BLUE "AURORAS" OVER SWEDEN: Yesterday in Sweden, sky watchers were puzzled when a strange ribbon of blue light appeared during a geomagnetic storm.

Space physicist Toshi Nishimura of Boston University took a look at the video. "It looks really odd if it's aurora," he says. "One auroral arc shouldn't cut across another auroral arc without disturbing it, so it's hard to explain this from an auroral physics point of view."

Russians are to blame for blue auroras

Another possibility is rocketry. Since late October Russia has been conducting ICBM firing exercises in the Barents Sea with the nuclear-powered missile cruiser "Peter the Great" in the area for combat training. Rocket exhaust has been known to create displays like this in the past.

However, no one saw a rocket. Multiple witnesses in Abisko agree that nothing streaked across the sky before the blue band appeared.

For now, the blue ribbon remains a mystery.

MYSTERY SOLVED? On Nov. 3rd, Russia's nuclear submarine Generalissimus Suvorov test-fired an ICBM from beneath the White Sea. This might be linked to a "blue aurora" widely seen from northern Sweden and Norway on the same date. The sightings are described below.

AR3141 on the other hand, is a larger sunspot located on the northeast (N15E74) it occupies an area of 150MH and although its magnetic complexity is also alpha, NOAA forecasts for this region a 25% probability of producing C-class flares.

AR3141 has grown in size and now encompasses an area of 460HM. The region now contains nine sunspots with beta complexity; however, according to SDO It has a relatively simple magnetic field that poses little immediate threat for strong flares.

AR3131 AND AR3139 are gone from the solar disk but a new region has emerged located in the northeast (N26E21) AR3142 is a small region of five sunspots with an area of 10MH with a beta magnetic field. It poses no threat for strong flares.


The total number of sunspots has decreased to 78 ( 18 of these are grouped into 6 active regions) NOAA forecast for the next 24h is 50% chance for C flares, 5% chance for M flares and 1% chance for X flares.

There are currently 7 numbered active regions on the solar disk: AR3135, AR3136, AR3137, AR3140, AR3141, AR3142 and new region AR3143

AR3141 has grown in size and now encompasses an area of 460HM. The region now contains nine sunspots with beta complexity; however, according to SDO It has a relatively simple magnetic field that poses little immediate threat for strong flares.

AR3141 located on the northeast (N15E37) is now a gigantic region with an area of 600HM (The size of the Earth is equivalent to almost 170MH) and a beta-gamma magnetic field that harbors energy for M-class solar flares. Any flares will be geoeffective as the sunspot is turning toward Earth


AR3143 located on the southeast (S14E56) is a group of two sunspots with an area of 20HM and a beta magnetic field. The probability of generating a C-class flare is 10% while for M and X it is 1%.

The total number of sunspots has increased to 80 (21 of these are grouped into 6 active regions) NOAA forecast for the next 24h is 65% chance for C flares, 25% chance for M flares and 10% chance for X flares. This is in response to the continued growth of AR3141

● Auroral Activity

The geomagnetic field has been at quiet to storm levels for the past 24 hours.

I don't know if there is a statistic of comets crashing into the sun, but lately NASA satellites have captured many of these bodies. This is the first time I have seen this, three comets sundiving one after another in the same trajectory.

There are currently 6 numbered active regions on the solar disk: AR3137, AR3140, AR3141, AR3142, AR3143 and new region AR3144

AR3144 located in the southwest (S25W20) is a small sunspot with an alpha magnetic field and an area of 5MH. It does not pose a threat of generating strong solar flares and is very likely to disappear on its westward trajectory.

QUIET WITH A CHANCE OF FLARES: Solar activiy is low, but the quiet could be short-lived. Big sunspot AR3141 has a 'beta-gamma' magnetic field that habors energy for strong M-class solar flares. Any explosions today (NOAA says there is a 15% chance) will be geoeffective as the sunspot is directly facing. SpaceWeather.com

The total number of sunspots has decreased to 81 (25 of these are grouped into 6 active regions) NOAA forecast for the next 24h is 65% chance for C flares, 15% chance for M flares and 5% chance for X flares.
