the The strongest geomagnetic storm in more than 20 years It hit Earth on Friday, with explosions of plasma and magnetic fields causing some radio outages and landslides Northern lights Stretching into the southern United States on Monday, officials warned that the storms are far from over.
The National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Prediction Center said early Monday that the G3, or “strong,” planet. Geomagnetic storm The warning was in effect until 2 a.m. ET. While stronger storms are no longer likely and conditions are expected to gradually weaken throughout the day, moderate to strong geomagnetic storms are “likely” on Monday, as well as smaller storms on Tuesday, the center said in its forecast.
The center also said that “solar activity is expected to be at high levels” with the possibility of more solar flares, or blasts of electromagnetic radiation from the sun.
The update came with the recording of another X-class solar flare. X-class flares are The strongest class Of these solar eruptions, the last one was recorded as “Moderate“.
“Flashes this big Not frequent“…Users of high-frequency (HF) radio signals may experience temporary degradation or complete loss of signal over a large portion of the sunlit side of Earth,” the center said.
A separate, stronger X-class flare was recorded on Sunday, and may have caused a high-frequency radio blackout for about an hour across wide areas on the sunlit side of Earth.
Torches came from Sunspot area 3664, a huge region of the Sun responsible for many of the flares and coronal mass ejections (CMEs) that led to the intense geomagnetic storm over the weekend. That spot remains “the most complex and active on the disc,” the National Oceanic and Atmospheric Administration (NOAA) said. This spot is so large that people wearing eclipse glasses can see it from Earth, measuring about 124,000 miles across, according to Space.com.
The National Oceanic and Atmospheric Administration (NOAA) said that spot was active along with Regio 3663, which along with 3664 is considered “magnetically complex and much larger than Earth.”
CMEs, or large explosions from the Sun’s atmosphere filled with plasma and magnetic fields that give rise to geomagnetic storms, are expected to continue throughout Monday and fuel G3 activity.
“Persistent but weaker CME impacts are expected to reduce responses to unstable G1 (secondary) levels on May 14,” NOAA forecasts.
Solar radiation storms, although minor, are also expected in the same time frame, as are more radio outages, although some of those events could be considered “strong” events depending on which solar flares erupt.
