Here’s when it’s dark enough to enjoy the northern lights in popular locations. If you haven’t yet planned your aurora adventure, now is the perfect time to start.

For those eager to catch this spectacle before it fades into the lighter skies, here are the last dates when it's still dark enough to see the northern lights

While the nights are still bright in northernmost aurora regions, in Churchill, Canada, the sun goes deep enough behind the horizon tonight for aurora to become visible in the sky.

The 27-day forecast predicts the maximum Kp5 geomagnetic activity level on Monday, Tuesday, and Wednesday. The 3-day forecast could be more optimistic and expects the Kp5 level on Tuesday and Wednesday.

The 27-day forecast shows low solar activity this week, with the maximum Kp4 geomagnetic activity level predicted on Tuesday.

As the sun gets more active on the way to the solar maximum, it surprises us regularly. Isn't it great news for the aurora photographers?

The sun is going to be quite active this week. Kp3-Kp4 level of geomagnetic activity is expected 6 out of 7 days this week. It's good news for those northern lights regions where the season is not over.

The 23 is becoming a magical date for aurora photography. We all remember great northern and southern lights dancing in the sky on March 23-24. It was Kp8 level of geomagnetic activity, which means a G4 geomagnetic storm. And again, there is the same Kp8 level on April 23-24.

The latest geomagnetic activity forecast doesn't promise that the March 23/24 event will repeat this week on April 20-21. And we'll have a third relatively calm week in a row with a maximum of Kp4 on the weekend. But the following week's forecast is fantastic, with 4 days of geomagnetic storms in one week.

This week will be as calm as the last one, with a maximum Kp4 level of geomagnetic activity on Tuesday or Wednesday, depending on your location. But as we can see, the next two weeks should be fantastic.

The geomagnetic activity will be getting higher and higher each week in April. The sun has decided to give a farewell northern lights show at the end of the season.

While the forecast for this week is updated from an earlier expected Kp4-5 to Kp3-4 on the weekend, we all remember what happened last week.

The forecast is updated from an earlier expected Kp4 to Kp6 on March 25 and Kp5 the next day. It should be a wonderful weekend. Fingers crossed.

The geomagnetic activity forecast is updated from an earlier expected Kp4 to Kp5 on March 15. It's good news. Get your cameras ready.

Solar activity is in decline and will increase only in the middle of the month, with expected Kp4 on March 15.
