Solar activity reached moderate levels. Newly assigned sunspot region 3030 just erupted with an M1.2-class solar flare. Radiation from the flare ionized the top of Earth's atmosphere, causing a shortwave radio blackout around the North Africa. Mariners and ham radio operators may have noticed unusual propagation effects at frequencies below ~20 MHz.

The sunspot responsible for today's blast has been visible for less than a day. Already it has unleashed 8 solar flares (seven Class flares and one M1.2-class flare). Future flares will become increasingly geoeffective as the active region turns toward Earth.


Thanks for watching!

Growing sunspot AR3032 exploded on June 13th (0407 UT), producing an M3-class solar flare that lasted more than 3 hours. Extreme ultraviolet radiation from the flare caused a shortwave radio blackout over Japan, Northern Australia, SE Asia, China, India,
Siberia, and Micronesia, affecting frequencies below 30 MHz.

Also, the explosion hurled a CME into space. The US Air Force detected a Type II solar radio burst, which is usually caused by shock waves in the leading edge of a CME. NOAA forecasters are analyzing the data to see if the CME has an Earth-directed component.

#53 Sonnensturm trifft am 15. Juni auf die Magnetosphäre der Erde - Geomagnetische Sturmwache

The CME associated with the M3.4 flare that occurred at 13/04:07 UTC, is likely to skirt the Earth's magnetosphere at approximately the same time the onset of a positive polarity coronal hole is expected to impact Earth.

The combined effects will likely produce G1-G2 storming with a chance for G3-Strong storm levels if conditions occur simultaneously.

"Coronal Holes" are vast regions in the sun's atmosphere where magnetic fields open up and allow solar wind to escape. They look dark in ultraviolet images because the hot glowing plasma normally contained there is missing. In this case, the plasma is making a beeline for Earth.

Active conditions are expected to continue into 16 June. Forecasters will be monitoring the situation and additional watches, warnings, or alerts will be issued if conditions warrant.


Thanks for watching!

A large coronal hole stretching across the northern hemisphere of the Sun is now facing Earth. NOAA forecasters say there is a chance of minor G1-class geomagnetic storm on July 6th, when a stream of solar wind is expected
to hit Earth's magnetic field.

"Coronal holes" are vast regions in the sun's atmosphere where magnetic fields open up and allow solar wind to escape. They look dark in ultraviolet images because the hot glowing plasma normally contained there is missing.

High-latitude sky watchers should be alert for auroras on July 6th when the solar wind arrives. G1-class storms can produce Northern Lights as far south as US states ranging from Maine to Washington.

There are currently 5 numbered active regions on the visible solar disk. Sunspot AR3046 has a 'beta-gamma' magnetic field that harbors energy for M-class solar flares.

CME Impact Sparks G1-Class Geomagnetic Storm
A magnetic filament on the sun erupted June 30th, hurling a CME into space.
The glancing blow sparked a minor G1-class storm earlier today (July 4, 2022).

Thanks for watching!

Happy 4th of July to all my U.S.A fiends!

Yesterday, July 7th, a crack opened in Earth's magnetic field--and it stayed open for nearly 14 hours. Solar wind poured through the gap to fuel a minor albeit long-lasting G1-class geomagnetic storm.

The crack was opened by a co-rotating interaction region (CIR), which hit Earth's magnetic field during the early hours of July 7th. CIRs are transition zones between fast- and slow-moving streams of solar wind. They contain shock waves that often cause geomagnetic storms. NOAA analysts think a CME might have been embedded in the solar wind just ahead of the CIR, thus delivering a double blow. https://spaceweather.com/

BIG SUNSPOT
Big new sunspot AR3053 is growing and turning toward Earth. The sunspot now has not just one but two dark cores wider than Earth. These dimensions make it an easy target for backyard solar telescopes.

#56 Solar Storm Incoming: Es wird erwartet, dass ein vollständiger Halo-CME an diesem Wochenende auf das Magnetfeld der Erde

Geomagnetic storms are possible on July 23rd when a full-halo CME is expected to hit Earth's magnetic field. The storm cloud was hurled toward Earth by a solar tsunami eruption. Soon after the explosion, the US Air Force reported a Type II solar radio burst. Characteristics of the burst suggested that a CME was tearing through the sun's atmosphere at a speed of 1063 km/s (2.4 million mph). The CME is squarely inside the Earth strike zone.

NOAA forecasters say that G1- to G2-class (minor to moderate) storms are likely with a slight chance of escalating to category G3 (strong).
