March 13, 1989: Quebec goes dark The Dynamics Explorer 1 satellite captured the March 1989 aurora over Earth's southern regions (left). Scientists then plotted that auroral map along northern magnetic field lines to create an approximation of what the aurorae probably looked like (right), although the satellite wasn't positioned to see the northern hemisphere. Credit: NASA/GSFC/Univ. of Iowa. In March of 1989, a highly active sunspot region released multiple extreme solar flares, including an X4.5 flare on March 10 and a M7.3 flare on March 12. Solar flares are ranked as B, C, M, and X class, with B being the weakest and X the strongest. Within B, C, and M classes, flare strength is further ranked from 1 to 9. X class flares are the strongest, and the class is open-ended – i.e., X-class flares can go higher than 9. These strong flares of 1989 launched massive coronal mass ejections (CMEs) at Earth, hitting the planet on March 13. The resulting disturbance was so large that aurorae were seen as far south as Texas and Cuba. In Quebec, where nonconductive bedrock couldn’t absorb the geomagnetically induced currents of the storm, the currents were forced into the Hydro-Quebec power grid. The province went dark, leaving 6 million people without power for nine to 12 hours. Operational glitches in power grids and communications systems were seen across the U.S. and Europe, as well, though none was as severe as the effects felt by Quebec. The event forced a paradigm shift in infrastructure preparation for geomagnetic storms. As a result, when multiple X-class flares hit Earth in the solar storm of May 2024, there was little effect on power grids.

A light green and turquoise line of Northern Lights spreads horizontally across the dark blue starry sky. At the bottom of the horizontal photo a narrow pier leads from the viewer to a green lighthouse that shines it also greenish light brightly right below the aurorae. In the background there is a line of smaller sea marks leading from the lighthouse to the left side of the horizon. In the left corner at the bottom there is my copyright saying 'C.

Vertical photo of the harbour entrance with the red lighthouse in the bottom right corner with its light glowing brightly and reflecting on the calm waters. From it, green and mostly pink aurorae spread high up and to the left. Above the Northern Lights, in the upper third of the image, there is the dark night sky showing the constellation Ursa Major crispy clear. On the horizon behind the lighthouse there is the shadow of another coastline with a bit of light pollution spreading behind it at one point.

Light green and pink Northern Lights above two lighthouses, one on each side of a harbour entrance, the green left one and the red right one matching the aurorae perfectly with the colours they also spread with their lights that shine brightly in the photo.

Softened green and turquoise Northern Lights spread above the sea across the dark starry sky, dissipating into the blackness. On the horizon on the left there are some vessels, brightly illuminated by their own lighting, and on the left there is a row of flashing sea marks.

#AuroraBorealis night + perfect #weather conditions yesterday; 2nd in a row so despite having work today I finally went to #Warnemünde for the rare chance of taking #photos of seaside #aurorae.

Coming back to this past week's #aurorae photos with a devil on both shoulders

Snapshot of a part of Euclid VIS detectors, almost saturated with cosmic ray hits.

Those were beautiful #aurorae in the past days. A solar storm brought a lot of protons to Earth. Not only to Earth but also to #ESAEuclid – but does #Euclid notice? Oh yes.

Aurora selfie! Jennifer Hoffman, a white woman with short red hair, stands in front of a nighttime neighborhood scene. A curving red curtain of northern lights arches above her head.

Okay, I've volunteered to be a media contact person for stories about this week's amazing #aurorae. Scientists, what are your favorite fun facts or useful similes? Non-scientists, what questions do you have that I could try to answer? 🔭🧪

Definitely mentioning that you can get an #auroraselfie!

NIT D'AURORA SAR SOBRE #CATALUNYA! Hem pogut gaudir-la des del Montseny a partir de les 4h45 CET quan era ben intensa i visible a ull nu. Unes imatges des del #MontsenyObservatory.
Com d'intensa serà la propera nit amb l'arribada del vent solar carregat per la massiva ejecció coronal? 🤩👇

Sept. 2, 1859: The Carrington Event peaks Like the Carrington Event, the May 2024 aurorae were strong enough to be seen much farther south than normal -- as in this shot, taken near Mazatlán, Mexico. Credit: René Saade ## Key Takeaways: * Richard Carrington's 1859 observation marked the first recorded instance of a solar flare. * The subsequent coronal mass ejection (CME) triggered the most intense geomagnetic storm on record, estimated to be at least twice the magnitude of any other in the preceding 500 years. * Observable effects included auroral displays at unusually low latitudes and widespread disruptions to telegraph systems. * While modern infrastructure and forecasting capabilities mitigate some risks, a recurrence of a Carrington-level event poses significant threats to technological systems, including power grids and global communications. Key takeaways sponsored by The Space Store On Sept. 1, 1859, amateur astronomer Richard Carrington observed a massive eruption of bright light from the Sun’s surface. It was the first recorded observation of a solar flare. Within only 17.5 hours, a coronal mass ejection (CME) – an expulsion of plasma and magnetic waves that often accompanies flares and prominences – reached Earth, causing the largest geomagnetic storm in recorded history. On the modern NOAA scale, it would have classified as a G5, the highest possible level, and research into ice core samples has suggested it was at least twice as large as any other storm for 500 years. Aurorae danced in the sky as far south as the Caribbean and Central America, lighting up the night. Telegraph systems worldwide failed, with sparks shooting from the machines and telegraph paper going up in smoke. Today, NOAA’s Space Weather Prediction Center can issue warnings and system improvements have been made since the strong 1989 and 2003 geomagnetic storms; infrastructure proved relatively resilient during the recent May 2024 storm. But a Carrington-level event could still have catastrophic consequences on modern GPS, satellites, global communications, and power grids.
