If You’ve Never Seen An Aurora Before, This Might Be Your Chance!

Tonight and the rest of the weekend could be your best chance ever to see the aurora.

The Sun has been extremely active lately as it heads towards solar maximum. A giant Earth-facing sunspot group named AR3664 has been visible, and according to Spaceweather.com, the first of an unbelievable SIX coronal mass ejections were hurled our way from that active region, and is now hitting our planet’s magnetic field.

Solar experts predict that people in the US as far south as Alabama and Northern California could be treated to seeing the northern lights during this weekend. For those of you in northern Europe, you could also be in for some aurora excitement. Check the Space Weather Prediction Center’s 30-minute Aurora Forecast for the latest information.

If the weather conditions are right in your area, you might hit the aurora jackpot.  See a map with predictions, below.

“If you happen to be in an area where it’s dark and cloud free and relatively unpolluted by light, you may get to see a fairly impressive aurora display, and that’s really the gift from space weather, is the aurora,” said Rob Steenburgh, from NOAA’s (National Oceanic and Atmospheric Administration) Space Weather Prediction Center (SWPC), during a briefing on Friday.

According to SWPC, the impact from the geomagnetic storm reached Earth-based magnetometers on May 10th at 1645 UT. More CMEs are following close behind and their arrival could extend the storm into the weekend.

While these solar storms could provide stunning views of auroras, there is also the potential for disruption to communications systems, power grids and satellite operations.

As we reported earlier this week, the Sun released three X-class solar flares — the strongest class of flares — in short succession. Solar flares are explosions on the Sun that release powerful bursts of energy and radiation coming from the magnetic energy associated with the sunspots. The more sunspots, the greater potential for flares.

The sunspot group AR3664 is so large, it is visible to the naked eye — but you MUST be wearing special eye-wear (got any of your eclipse glasses left from April 8?) or use special solar filters for telescopes or binoculars. AR3664 is enormous, about 10 times the size of Earth.

How to see the Northern Lights

The aurora is an incredible sight. Your best shot to see it is to be in a dark area.

“Get away from city lights into a dark, rural surrounding and look north,” said the National Weather Service in St. Louis, Missouri on X (Twitter). “Aside from some clouds associated with a passing front, much of the time looks mostly clear.”

Check the weather forecast in your region for cloud cover. But if you don’t have any luck tonight, check again Saturday or Sunday night. With multiple CMEs, the storm was expected to last through the weekend.

Good luck!
