SUMMARY

The Sun has unleashed the third most powerful solar flare in recorded history, with potential impacts on Earth expected mid-day Wednesday. This solar storm, classified as "severe," may produce vibrant northern lights visible in mid-latitudes of the United States and Europe. Historical context indicates that solar activity cycles, such as the Maunder Minimum, correlate with significant climate changes, although individual solar flares do not directly affect weather patterns. Observations of the northern lights have been reported across various locations, including New Hampshire and Washington State.

PREREQUISITES
  • Understanding of solar flares and their classifications
  • Familiarity with geomagnetic storms and their effects on Earth
  • Knowledge of the Maunder Minimum and its historical significance
  • Awareness of the relationship between solar activity and climate change
NEXT STEPS
  • Research the effects of solar flares on satellite operations and communications
  • Explore the science behind auroras and their visibility conditions
  • Study the historical impacts of solar activity on Earth's climate
  • Investigate current solar observation tools and technologies
USEFUL FOR

Astronomers, climate scientists, meteorologists, and anyone interested in solar phenomena and their implications for Earth.

The Sun today unleashed what appears to be the third most powerful flare in recorded history, a storm of charged particles that could hit Earth mid-day Wednesday with more effect than any since 1989, when an entire Canadian province had its power knocked out.

Depending on the storm's magnetic orientation, it could set off a dramatic display of colorful northern lights well into mid-latitudes of the United States and Europe.

it is interesting...does anyone know what time it hit earth? here on the pacific coast, at 3am i woke up to a huge power surge and then the electricity was out...
 
Say, I was just curious. How many of you were invited to stay in the US government survival bunker for the elite? It is hoped that we'll be able to rebuild society after the solar disaster wipes out life on the surface. I'm in sector 7-G, look me up.

Sorry Njorl, I had to cut life support to that sector. Before you're gone, here's an update.

i remember learning in school MANY years ago that the sun directly affected wind...because of this flare up, will we have windy weather ahead?

There is no known relationship between individual solar flares and weather. There is, however, evidence for a relationship between the solar activity cycle and global climate. The best known case is the correlation of a long period of solar inactivity called the Maunder Minimum (1645-1715) with the lowest temperatures recorded during the "Little Ice Age" that occurred from 1500 to 1850. Almost no spots were observed on the Sun during this period. There is evidence for the correlation of other periods of low solar activity with cooler temperatures on Earth as well.

there may be better information on the net, or PF members may
know more, i came across this one.
 
Great shot of the Northern Lights: USA Today

New, major solar storm slams into the Earth
The geomagnetic storm level is was listed as "severe" and magnetic field of the new cloud is pointing south, which means it could interact much more violently that if the magnetic field is pointing north, the same way as the Earth's, Harvard-Smithsonian Center for Astrophysics (CfA) scientists said.

That is true, but that's got nothing to do with solar flares. Wind is a result of radiative heating of the ground, which naturally occurs on a daily cycle. In the morning, the ground is cool and about the same temperature as the air. And the air is still. By late morning or early afternoon, the ground is heated by the sun to be much warmer than the air. Warm air rises like bubbles in boiling water causing convection currents and wind.

We had amazing "northern lights" here in NH on Oct 30. Quite the treat...I had never seen them before.

Lucky dog! I have looked and looked but no lights on the west coast at the 45th parallel. They were seen up in Washington though.

I once got to see a glimse of them, way off in the distance, and while at 30,000 feet over Colorado. That's it for me. I would love to see a dramatic display...should have gone to Alaska this week.

This would be a fairly short trip for me, but this would be no small trip from Hong Kong.

KL, as I understand things, [I saw this on a TV show so who knows?] the japanese believe children concieved under the Aurora are specially blessed. Do the Chinese have any similar beliefs?

No, I haven't heard of it. :smile:
I think the next time when the sun turns so active, I won't mind traveling as close to the north pole as possible so as to witnesses a facinating auroras show.

By the way, from the pictures in spaceweather.com, the giant group of sunspots is rotating away from us.

A friend of mine lives in El Paso, TX he said he saw the Northern Lights.
