Solar Flare Erupts from Sun, Geomagnetic Storm Alert Issued
As of now, there is no information available regarding the anticipated CME cloud that is expected to have a minor impact on Earth today. However, scientists are worried about another solar flare eruption that occurred on June 23 in the same area, sunspot AR3341, which was responsible for the X1-class flare that caused a significant short-wave radio blackout on June 20. Although the recent flare did not result in a blackout, it is uncertain whether it could trigger a geomagnetic storm on our planet.
Space Weather Physicist Dr. Tamitha Skov, also known as the Space Weather Lady, mentioned in her forecast, “This week our Sun will really kick things up a notch as Area 3341 fires X1.1 flares, M4.9 flares and triggers two near-Earth geomagnetic storms. Although the storms will likely just grazing the Earth, we may have a bit of a bumpy ride especially at high latitudes.Aurora may be visible sporadically throughout the week.
He added that there is a high risk of radio outages over the next five days, which could be a concern because this weekend is Field Day, an annual amateur radio competition where many regions practice how to rapidly deploy radio communications in an emergency. situations.
Concern about geomagnetic storms is growing
The fear of radio outages comes from the notorious solar region AR3341, which has already produced two massive solar flares. Skov said: “We probably won’t get another X-flare from area 3341, but large M-flares are definitely possible, along with an Earth-bound solar storm or two. This means that for many radio operators, Field Day will involve a lot of noise and intermittent interference on the bands during the day during.
In addition, a geomagnetic storm can also cause a number of problems, such as disruptions to mobile networks and GPS, damage to satellites, power grid disruptions and more.
How the NASA Solar Dynamics Observatory monitors solar activity
The NASA Solar Dynamics Observatory (SDO) houses a full suite of instruments for observing the Sun, and has done so since 2010. It uses three very important instruments to collect data on various solar activities. They include the Helioseismic and Magnetic Imager (HMI), which measures high-resolution longitudinal and vector magnetic fields across the entire visible solar disk, the Extreme Ultraviolet Variability Experiment (EVE), which measures the Sun’s extreme ultraviolet radiation, and the Atmospheric Imaging Assembly (AIA), which provides continuous full-disk observations of the solar chromosphere and the corona in seven extreme ultraviolet (EUV) channels.
