#Wikipedia - 2003 Halloween #SolarStorms
"The Halloween solar storms were a series of solar storms involving solar flares and coronal mass ejections that occurred from mid-October to early November 2003, peaking around October 28–29. This series of storms generated the largest solar flare ever recorded by the GOES system, modeled as strong as X45 (initially estimated at X28 due to saturation of GOES' detectors).
Effects On Earth
"Satellite-based systems and communications were affected, aircraft were advised to avoid high altitudes near the polar regions, and a one-hour-long power outage occurred in Sweden as a result of the solar activity. Aurorae were observed at latitudes as far south as Texas and the Mediterranean countries of Europe. Twelve transformers in South Africa were disabled and had to be replaced, despite the country's low geomagnetic latitude.
On satellites and spacecraft
"The SOHO satellite failed temporarily and the Advanced Composition Explorer (ACE) was damaged by the solar activity. Numerous other spacecraft were damaged or experienced downtime due to various issues. Some of them were intentionally put into safe mode in order to protect sensitive equipment. Astronauts aboard the International Space Station (ISS) had to stay inside the more shielded parts of the Russian Orbital Segment to protect themselves against the increased radiation levels.
"Emissions from the CME were later observed by the Mars Odyssey spacecraft orbiting Mars, Ulysses spacecraft near Jupiter, and the Cassini spacecraft en route to Saturn. In April 2004, Voyager 2 was also able to detect them as they reached the spacecraft."

Solar flares, #sunspots, and geomagnetic storms—oh my! 🌞🔭 Apparently, we need a PhD in #Astrophysics just to understand this avalanche of jargon about cosmic burps. 🙄 After all, what's a little G4 storm when we're already drowning in acronyms? 🌌😂

Your Smartphone Can Measure Solar Storms! ☀️🧲
Industry researchers found a way to provide better global coverage of what dynamics are occurring in the turbulent ionosphere - a region of Earth's atmosphere that is affected by the Sun's activity. They did this by tapping into GPS signals transmitted between smartphones and satellites.

I think I've found the antenna that works for me during these #geomagneticstorms. @Buddipole Deluxe Antenna setup as a #buddistick for 40,30,20,17,15,12 and 10 meters makes a #Morsecode #POTA #parksontheair activation easy. Photo:20m setup.

Among the collected data…a dramatic motion of the air away from the aurora causing the formation of enormous vortices that moved air in a spiral larger than a hurricane…
"As the aurora intensifies, you see more lights, but along with that, there's more energy entering the atmosphere, so it makes the atmosphere near the poles very hot, which starts to push air away from the poles and towards the equator," so co-author, Virginia Tech's Scott England.

"Scientists at the Skolkovo Institute of Science and Technology (Russia), together with colleagues from the Leibniz Institute for Astrophysics (Germany), the University of Graz & the Kanzelhöhe Observatory (Austria), the University of Zagreb and Zagreb #Astronomical Observatory (Croatia) have developed a method to predict #GeomagneticStorms directly from #solar observations.
The results make it possible to increase the lead warning times from hours to days. cont..."
