Aurora Alarm! Few coronal mass ejected to block the earth’s magnetic field

Aurora Alarm! A massive filament exploded from the Large Sunspot Region (AR 2860) on August 28. The resulting coronal mass ejection, or CME — a super-combusting gas bubble from our sun — joins an earlier CME created in a solar flare from the same region on the sun earlier in the day. Now all of the CME is going our way. They are expected to cause a beautiful display of the aurora borealis. photo via

High latitude aurora warning This morning (September 1, 2021) says two huge bubbles of super-hot gas from our sun – otherwise known as coronal mass ejections or coronal mass ejections. CME’s – towards the ground. There is no danger to us on Earth. These coronal mass ejections are not powerful enough to hit satellites or power grids. But they are about to “joke” our planet’s magnetic field, creating a beautiful display of the aurora borealis at high latitudes. SpaceWeather said:

Estimated time of arrival: 1-2 September. Meteorologists from the National Oceanic and Atmospheric Administration (NOAA) expect strong geomagnetic storms like Category G2. This means that people as far south as Idaho and New York (55° geomagnetic latitude) can see the aurora borealis.

Early last week, sun-watchers began noticing an increase in solar activity as Active Solar Region 12860 (AR 2860) produced 8 Class C solar flares. UTC (1:30 a.m. EDT) The largest area produced M4.7 Solar flare. The glow was clearly visible at 131 . A The wavelength ranges from NASA’s Solar Dynamics Observatory. It showed that solar plasma temperatures are in excess of 10 million degrees. The event caused a slight radio dimming on the sun-facing side of the Earth (see image below). This event triggered a coronal mass ejection (CME) targeting Earth. However, this continuous medical treatment was not expected to have such a large effect on the Earth region.

Now 2 CME is on the way

But later that day, a room climate explained, huge strings Magnetism erupted on the sun. This huge arc of electrified gas in the Sun’s atmosphere produced the second largest mass on Earth. Now, the two CMEs are moving side by side through space to Earth. SpaceWeather said:

NOAA viewers expect CME to deliver a double whammy separated by hours. The first CME can teach a minor G1 is great A geomagnetic storm late September 1. The second CME can intensify the storm, making it rather strong G2 . class It happened on September 2.

Storms like these do not damage power grids or satellites. However, they can produce beautiful auroras at high latitudes. Light show is possible in Scandinavia, Iceland, Canada and even some North American countries.

M4.7 solar flare from AR 2860 caused minor radio interference on August 28. That is, it caused weak degradation of high-frequency radio communications and low-frequency navigation signals. Sunspot data is SDO HMI visible light data from: The glow data is a GOES X-ray provided by the NOAA Space Weather Prediction Center (SWPC). NOAA SWPC Wireless Dimming Zone.

The active solar region produced 12,860 major eruptions and 2 Earth-guided coronal mass ejections (CMEs) on August 28. The CME is expected to hit Earth’s magnetosphere together, creating a beautiful display of the aurora borealis around September 1-2, 2021.

Aurora Alert. Here’s the AR 2860 on August 30

Soon, the sun’s rotation will throw her out of sight. Victor wrote: “As we have just seen, the Sunspot AR 2860 through thin clouds is a large group… The sunspot cluster contains more than a dozen dark cores spanning 200,000 km.

Conclusion: Aurora Alert. Two AR 12860 CME cross space toward Earth and are expected to create a stunning display of the aurora borealis at high latitudes.
