SOLAR CYCLE ACTIVITY REPORT JANUARY 11/2023

The region that erupted almost simultaneously with the X1.9 flare was assigned the number 13186 and debuted a few hours ago with an X1.06 class flare at 22:47 UTC on January 10. Prior to this X-class flare, solar activity was moderate with some M-class flares:

● M1 from AR3184 at 02:16 UTC produced a Minor R1 Radio blackout over Oceania
● M2.6 from AR3181 at 02:41 UTC produced a Minor R1 Radio blackout over Oceania
● M1 from AR3184 at 11:08 UTC produced a Minor R1 Radio blackout over Indian Ocean
● M1.35 from AR3186 at 17:28 UTC produced a Minor R1 Radio blackout over South America
● M1.25 from AR3184 at 17:48 UTC produced a Minor R1 Radio blackout over South America
● X1.06 from AR3186 at 22:47 UTC produced a Strong R3 Radio blackout over South west Pacific Ocean

● M5.67 from AR3184 at 01:30 UTC on January 11 produced a Moderate R2 Radio blackout over Oceania

CME THIS TIME: Yesterday's X1.9-class solar flare did not hurl a CME toward Earth. Although it was intense, the blast was too brief to lift a CME out of the sun's atmosphere. Next time may be different. There are now three large sunspots (AR3181, 82 and 84) with unstable 'delta-class' magnetic fields capable of strong explosions. SpaceWeather.com

What magnetic connection is there on that side of the sun that is provoking violent reactions?

SOLAR FLARE CAUSES RARE 'MAGNETIC CROCHET': The X-flare of Jan. 9th did something rare. It jerked Earth's magnetic field. Here is a composite of magnetometer recordings from Boulder, Colorado; Honolulu, Hawaii; and Fredericksburg, Virginia:

The "jerk" is circled in yellow. It began around 1846 UT, and was detected by many magnetic observatories across the dayside of Earth.

The phenomenon is called a 'magnetic crochet.' Radiation from the flare ionized the top of Earth's atmosphere and caused currents to flow 60 km to 100 km above Earth's surface. These currents, in turn, briefly altered Earth's magnetic field. Everything returned to normal a few minutes later. SpaceWeather.com​

There are currently 8 numbered sunspot regions on the solar disk: AR3180, AR3181, AR3182, AR3183, AR3184, AR3185 and new regions AR3186 and AR3187

AR3186 located on the northeast (N25E65) is a group of five sunspots with size 100HM and beta-delta magnetic field. NOAA forecasts 85% chance for C flares

Preliminary data for AR3187: it is located on the northeast (N13E18) is a group of two sunspots with size 10HM and magnetic field. It poses no threat for strong solar flares.

The total number of sunspots has increased to 175 (115 of these are grouped into 8 active regions) NOAA forecasts for the next 24h: 99% chance for C flares, 70% chance for M flares and 35% chance for X flares.

POLAR CAP ABSORPTION EVENT: Yesterday, Jan. 13th, Earth-orbiting satellites detected a pulse of energetic protons from the sun. When they hit Earth, a polar cap absorption event (PCA) occured:

Shortwave radio signals around the South Pole were abruptly attentuated. Why? Protons funneled by Earth's magnetic field into the Antarctic atmosphere ionized the D-layer of the ionosphere. This disrupted the normal propagation of radio signals at frequencies below ~30 MHz.

The PCA lasted for hours and would have blacked out radio communications for any airplanes flying over the South Pole. PCAs are a bigger problem when they occur over the North Pole where "great circle" air traffic is busier. The time for *that* is northern summer when the North Pole is tipped toward the sun. More PCAs are in the offing as Solar Cycle 25 intensifies. SpaceWeather.com​

SOLAR CYCLE ACTIVITY REPORT JANUARY 17/2023

Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C8 event observed at 09:23 UTC on January 16 from Region 3182 (S17W75).
Several regions considered to be dangerous are now facing the Earth, however, as has happened on other occasions, solar activity is low compared to when these regions are emerging from the west or rotating to the east.

There are currently 9 numbered sunspot regions on the solar disk: AR3182, AR3184, AR3185, AR3186, AR3188, AR3190, AR3191, AR3192, AR3193 and AR3194. AR3185 is gone

Big sunspot AR3190 located on the southeast (S14E29) with 880 millionths of a hemisphere has a 'beta-gamma-delta' magnetic field that harbors energy for X-class solar flares.

https://twitter.com/x/status/1615096179968163842

NAKED-EYE SUNSPOT: One of the biggest sunspots in years (AR3190) is crossing the solar disk--and you can see it with the naked eye. "Be sure to use safe solar glasses to protect your eyes," says Bum-Suk Yeom of Iksan, South Korea. "I tried it myself today, and I could see the sunspot clearly."

The sunspot is four times wider than Earth. It's twice as big as any other spot on the sun, visible to the naked eye, and a magnificent target for backyard solar telescopes.​

Best of all, it's about to explode. AR3190 has an unstable 'beta-gamma-delta' magnetic field that harbors energy for X-class solar flares. Any eruptuions will be geoeffective because the sunspot is almost directly facing Earth. SpaceWeather.com ​

The total number of sunspots has increased to 186 (96 of these are grouped into 9 active regions) NOAA forecasts for the next 24h: 99% chance for C flares, 60% chance for M flares and 15% chance for X flares.

In 1859, astronomer Richard Carrington was studying the Sun when he witnessed the most intense geomagnetic storm recorded in history. The storm, triggered by a giant solar flare, sent brilliant auroral displays across the globe and causing electrical sparking and fires in telegraph stations.

Short Wave's scientist-in-residence Regina G. Barber talks to solar physicist Dr. Samaiyah Farid about what's now known as the Carrington event and about what may happen the next time a massive solar storm hits Earth.

There are currently 10 numbered sunspot regions on the solar disk: AR3184, AR3186, AR3190, AR3191, AR3192, AR3194, AR3195, AR3196 and new regions AR3197 and AR3198

AR3185, AR3188, AR3193 are gone. Sunspots AR3190 and AR3192 have 'beta-gamma' magnetic fields that harbor energy for M-class solar flares.

AR3197 located on the northeast (N24E44) is a group of 4 sunspots with an area of 10HM and a beta magnetic field. It poses no threat for strong solar flares according to preliminary data.

AR3198 located on the northeast (N27E56) is a group of 6 sunspots with an area of 30HM and a beta magnetic field. It poses no threat for strong solar flares according to preliminary data.



The total number of sunspots has increased to 166 (66 of these are grouped into 10 active regions) NOAA forecasts for the next 24h: 99% chance for C flares, 60% chance for M flares and 15% chance for X flares.

There are currently 11 numbered sunspot regions on the solar disk: AR3184, AR3186, AR3190, AR3191, AR3192, AR3194, AR3195, AR3196, AR3197, AR3198 and new region AR3199

AR3199 located on the northeast (N16E63) is a group of 5 sunspots with size 40HM and a beta magnetic field. Preliminary data indicates that this region poses no threat for strong solar flares.

AR3190 and AR3192 continue to have beta-gamma magnetic complexity that harbor energy for M-class solar flares.

GIANT SUNSPOT This is AR3190, one of the largest sunspots of surging Solar Cycle 25. "It's almost five times the diameter of Earth, and could be seen through the thick humid atmosphere over the Gulf of Mexico.

A 'LIGHTNING BOLT' ON THE SUN: Imagine a bolt of lightning half-a-million kilometers long. Actually, no need to imagine. Here it is:

This enormous plasma discharge zig-zagged through the sun's atmosphere yesterday, Jan. 19th, briefly connecting two sunspots AR3192 and AR3190 with a 500,000 km-long current dwarfing any terrestrial lightning.

The upshot of the bolt was ... nothing. No CME or other debris emerged from the area. Currents and hot plasma were contained inside the crooked channel. SpaceWeather.com

Another M1.1 was observed at 12:26 UTC from Region AR3190 (S15W45) it produced a Minor R1 Radio blackout over Africa

https://twitter.com/x/status/1617332428862853120

There are currently 09 numbered sunspot regions on the solar disk: AR3190, AR3191, AR3192, AR3194, AR3195, AR3196, AR3197, AR3198 and AR3199. AR3186 is gone.

AR3194 located on the southwest has grown in size (130HM) and magnetic complexity. Currently poses a beta-gamma-delta magnetic field and produced a M-class flare already


On the other hand, AR3190 located to the southwest, has also grown in size (720HM) however, its magnetic complexity remains beta-gamma-delta and it produced a M1.1 class flare on January 22. Sunspot AR3190 harbors energy for X-class solar flares.

Both regions AR3190 and AR3194 are a few days away from leaving the solar disk and, as has been the case lately, they are likely to say goodbye with a strong flare.

The total number of sunspots has decreased to 166 (76 of these are grouped into 9 active regions) NOAA forecasts for the next 24h: 99% chance for C flares, 55% chance for M flares and 10% chance for X flares.
