SOLAR CYCLE ACTIVITY REPORT DECEMBER 04_2023

Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C4 event observed at 08:06 UTC from Region 3494 (S17W96).​

There are currently 8 sunspot regions on the solar disk: AR3500, AR3501, AR3505, AR3507 AR3508, AR3509 and new regions AR3510
AR3511

AR3494 & AR3503 are gone

Total number of sunspots has increased to 107 (27 of these are grouped into 8 active regions) NOAA forecasts for the next 24h: 99% chance for C flares, 30% chance M flares and 5% chance for X flares. Sunspot region AR3500 has a beta-gamma magnetic field that harbors energy for M-class flares but it will be leaving the solar disk in the next few hours. All other regions have stable magnetic fields.​

● Auroral Activity

The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. On December 3 Solar wind speed reached a peak of 502 km/s (Moderately high speed) at 20:56 UTC. Total IMF reached 10 nT at 21:08 UTC​

GEOMAGNETIC STORM WATCH (G2): Earth's magnetic field is about to receive a double blow. First, on Dec. 4th, a high-speed stream of solar wind flowing from a coronal hole will arrive. Then, on Dec. 5th, an off-target CME could deliver a glancing blow. Their combined effect is expected to cause G1 (Minor) to G2-class (Moderate) geomagnetic storms with photographic auroras at mid-latitudes. SpaceWeather.com

A HOLE IN SUN'S ATMOSPHERE: A huge hole has opened in the sun's atmosphere, and it spewing a stream of solar wind directly toward Earth. NASA's Solar Dynamics Observatory photographed the structure, which stretches almost 800,00 km along its long axis:​

This is a coronal hole--a region in the sun's atmosphere where magnetic fields have opened up, allowing solar wind to escape. The hole looks dark because hot glowing gas normally contained there is missing. The gaseous material is on its way to Earth.​

The solar wind is due to arrive Dec. 4th or 5th. Together with a glancing-blow CME, also en route, it could spark G1 (Minor) to G2-class (Moderate) geomagnetic storm. SpaceWeather.com​

Since the coronal hole seems to double in size month by month I wonder what it will look like in January February, etc., on the assumption that it would always be present on the visible face of the Sun...

UPDATED GEOMAGNETIC STORM WATCH (G1): NOAA forecasters have downgraded the current geomagnetic storm watch from G2 (Moderate) to G1 (Minor). This is in response to the late arrival of a solar wind stream flowing from a huge coronal hole. Despite this development, high-latitude sky watchers should remain alert for auroras on Dec. 5th. A glancing-blow CME may yet provide a light show. SpaceWeather.com

A double punch from the Sun inbound

A NEW SOURCE OF FLARES: New sunspot AR3513 is rapidly growing and crackling with M-class solar flares. The explosions will become geoeffective later this week when the sunspot turns toward Earth. Solar flare alerts: SMS Text

Above: New sunspot AR3513 has produced more than a dozen solar flares since it emerged on Dec. 5th.

SpaceWeather.com -- News and information about meteor showers, solar flares, auroras, and near-Earth asteroids

BIRTH OF A NEW METEOR SHOWER? A new preprint by respected meteor forecaster Jeremie Vaubaillon and colleagues urges sky watchers to be alert for a new southern hemisphere meteor shower in Dec. 2023. "We predict the birth of a new shower on Dec. 12, 2023, between 8:00 and 12:30 UT," the authors write. "The location of the radiant is close to the star λ-Sculptoris star, so a possible name for the shower is λ-Sculptorids." The source of the display, if it occurs, would be Comet 46P/Wirtanen.

Solar activity has been at moderate levels for the past 24 hours. Sunspot AR3513 (N19E53) is still very active and on December 6th produced two M-class flares.​

● M2.1 at 05:41 UTC the flare caused a Minor R1 radio blackout over Indian Ocean



● M2.3 at 21:44 UTC the flare caused a Minor R1 radio blackout over Pacific Ocean

A 'SIGMOID' ERUPTION ON THE SUN: When you see an "S" on the sun, it usually means something is about to explode. NASA's Solar Dynamics Observatory recorded this classic example of a "sigmoid eruption" on Dec. 6th:​

​

In the movie, an S-shaped magnetic filament erupts, creating a 'splash' of debris more than 100,000 km wide. Researchers have long known that sigmoid structures in the sun's atmosphere herald strong explosions. The magnetic field lines that comprise them are twisted like a slinky; when enough tension builds up, they un-twist explosively.​

Usually, sigmoid explosions produce CMEs. This one *might* have hurled a faint CME toward Earth. We're not sure because multiple CMEs were leaving the sun at the time of the blast, and there was much confusion. Don't be surprised if a sigmoid CME delivers a weak but direct blow to Earth's magnetic field on Dec. 9th. SpaceWeather.com​

A CME IS HEADING FOR MARS: Earlier today, a full halo CME left the sun. Analysts believe it will miss Earth. Instead, it is heading for Mars. NASA models suggest a direct hit on Dec. 11th. The impact will probably spark ultraviolet auroras and erode a small amount of the Red Planet's atmosphere. SpaceWeather.com

Solar activity has been at low levels for the past 24 hours but we have active conditions (kp 4) right now which means auroras for those who can see them if they are at high latitudes. The largest solar event of the period was a C9 event observed at 1515 UTC from AR3511 already in the far side​

There are currently 8 sunspot regions on the solar disk: AR3513, AR3514 AR3515, AR3516, AR3517, AR3518 and new regions AR3519 AR3520

Total number of sunspots has increased to 114 (34 of these are grouped into 8 active regions) NOAA forecasts for the next 24h: 80% chance for C flares, 30% chance M flares and 5% chance for X flares. All regions have stable magnetic fields.​

● Auroral Activity

The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. On December 13th Solar wind speed reached a peak of 390 km/s (Normal speed) at 04:44 UTC. Total IMF reached 9 nT at 08:41 UTC​
