Head’s up, aurora chasers! A surge of speedy photo voltaic wind is at the moment hurtling towards Earth at speeds as much as 430 miles per second (700 km/s) and the situations may spark geomagnetic storms tonight (April 17) and tomorrow (April 18)
NOAA’s Space Weather Prediction Center has issued a reasonable (G2) geomagnetic storm watch whereas forecasters on the U.Ok. Met Office say there’s a probability of sturdy (G3) bursts if exercise intensifies.
Geomagnetic storms are ranked on a G-scale, from G1 (minor) to G5 (excessive). Stronger storms can push auroras a lot farther from the poles, making them seen throughout mid-latitudes.
Auroras type when photo voltaic wind interacts with Earth’s magnetic subject, sending charged particles into the higher environment. There, they collide with gases akin to oxygen and nitrogen, transferring vitality that’s launched as gentle, producing the colourful shows seen within the night time sky. The stronger the photo voltaic wind, the extra dynamic and widespread the auroras can turn into.
Where can I see the northern lights tonight?
Depending on whether conditions align and geomagnetic storms are triggered, the northern lights could become visible across the northern U.S. tonight. But remember, auroras are never guaranteed and depend on how successfully the solar wind interacts with Earth’s magnetic field.

What time should I look for the northern lights tonight?
The northern lights may be visible across northern U.S. states tonight and tomorrow (April 17-18).
According to NOAA’s 3-day forecast, exercise is predicted to peak throughout the next home windows:
|
Time (EDT) |
Time (GMT) |
Activity |
|---|---|---|
|
5:00 p.m. (April 17) to 2 a.m. |
2100 (April 17) to 0600 (April 18) |
Moderate G2 situations potential |
|
2:00 a.m. to five a.m. |
0600-0900 (April 18) |
Minor G1 situations potential |
How can I see the northern lights from the place I stay?
Find a north-facing vantage level with a transparent view of the northern horizon, as removed from gentle air pollution as potential.
- Use your cellphone digital camera to scan the sky, as a cellphone digital camera is nice at selecting up faint auroras earlier than your eyes spot them. This offers you a good suggestion of which route to focus your consideration.
- Try and let your eyes adapt to the darkish for no less than half-hour; this can assist your night time imaginative and prescient develop.
- Wear heat clothes! Part of the enjoyable of aurora searching is the chase. Be ready to take a seat or stand for hours if situations are trying promising, as you will not need to miss the present when it begins!
We advocate downloading an area climate app that gives aurora forecasts primarily based in your location. One choice I take advantage of is “My Aurora Forecast & Alerts,” accessible for each iOS and Android. However, any comparable app ought to work properly.
While you are at it… search for Lyrid meteors!
If you are heading outdoors tonight or over the weekend to hunt for auroras, hold a watch out for the Lyrid meteor shower too.
The Lyrid meteor shower is active between April 16 and April 25 and will peak in the predawn hours on April 22.
Lyrids will appear to emanate from the radiant in the Lyra constellation, which rises in the northwest and climbs higher in the sky toward the early morning hours. But make sure you don’t look directly at the radiant, as while meteors appear to originate from Lyra, the longer, more dramatic shooting stars often appear farther away, so scan as much of the sky surrounding the radiant as possible.
