The expected strong Coronal Mass Ejection reached Earth just before 11h UT 01 December. Magnetometers showed a strong deflection. Aurora is being reported by amateur radio operators down to approx 55°N over Europe.
NOAA SWPC has updated the CME predictions to include no less than four CMEs which are due to arrive in the next couple of days.
"With 3 CMEs already inbound, the addition of a 4th, full halo CME has prompted SWPC forecasters to upgrade the G2 Watch on 01 Dec to a G3 Watch. This faster-moving halo CME is progged to merge with 2 of the 3 upstream CMEs, all arriving at Earth on 01 Dec. G3 (Strong) conditions are now likely on 01 Dec."
Another #solarstorm erupting which may slam into Earth's atmosphere towards late Friday. As we in the WDEF News 12 viewing area may see more clouds and rain soon, probably won't have a chance (small as it may be) of seeing the northern lights. Areas north of I-70 will stand the best chance of seeing between the clouds.
Yesterday's solar flare launched a CME that is visible in this Nasa/SDO video, filtered to show the solar atmosphere.
Solar active region "AR3500" erupted with a moderate M9.8 (that's almost an "X") flare yesterday evening. This active region is facing directly towards Earth, and a CME was detected which is predicted to reach us around midday on Dec 1st. Two smaller CMEs are already en-route which will start to affect us from the 29th.
Dr Tamitha Skov is predicting geomagnetic levels of G3 to G4 on Dec 1st. There shouldn't be any danger to infrastructure at these levels although some poorly shielded satellites could be at risk.
The attached video from NASA/SDO is filtered to show the sun's atmosphere (AIA211). The large dark patch on the left is a large coronal hole which will be leaking the solar wind into space. We will feel the effects of this coronal in the few days following the CME.
A notable #geomagnetic storm is expected to result from the arrival of a coronal mass ejection that erupted from the surface of the sun ☀️ on 📆 Saturday, Sept. 16 and was aimed in the direction of #Earth.
Analysts believe that a direct hit by an extreme #CME such as the one that missed Earth in 📆 July 2012 could cause widespread power blackouts, disabling everything that plugs into a wall socket 🔌. Most people wouldn't even be able to flush their toilet 🚽 because urban water supplies 💧 largely rely on #electric pumps https://science.nasa.gov/science-news/science-at-nasa/2014/23jul_superstorm
Think of Earth’s atmosphere like a bicycle tire. When the first solar storm hit, its #magnetic 🧲 field drove currents that caused Earth’s upper atmosphere and particles to move in one direction. When the second surprise solar storm hit, it was oriented in such a way as to cause the motion of Earth’s upper atmosphere to reverse direction. The friction and energy of the two opposing forces released heat in quantities more than models had anticipated https://www.washingtonpost.com/weather/2022/02/12/spacex-starlink-explainer-storm-sun/
#Computer errors 🐞 from #OuterSpace from a vote-counting machine that added thousands of non-existent votes to a candidate's tally, to a commercial #airliner ✈️ that suddenly dropped hundreds of feet mid-flight ⤵️, injuring dozens of passengers. A pacemaker's ❤️ built-in computer data got corrupted mid-flight. A group of researchers investigated more than 2,000 bit errors logged by a #satellite 🛰️ over roughly two years in #orbit. A huge number of the errors were clustered in an area called the South Atlantic Anomaly. According to #Nasa, #astronauts 👨🚀 on the #SpaceShuttle used to notice that their #laptops 💻 sometimes crashed when the space shuttle passed through the #SAAhttps://www.bbc.com/future/article/20221011-how-space-weather-causes-computer-errors
From #satellite 🛰️ imagery for monitoring 👀 vast forest areas to #GPS 🧭 systems essential for precise data collection and effective communication, technology is at the heart of contemporary #forest 🌲🌳 management. Beyond technological disruptions, #solar ☀️ superstorms could also have a profound impact on the ecological balance within forest ecosystems. The #downtime ⛔ in forest management and conservation efforts, coupled with the potential #ecological impacts, could have far-reaching consequences for the global economy 〽️ https://forestry.com/editorial/the-hidden-threat-of-solar-superstorm-a-forestry-perspective/
