Aurora Borealis in Czech Republic, May 2024

Red aurora borealis in Czech Republic, May 2024

I supposed that my November post about the barely visible northern lights will be a rare result for a long while. Well, there was very strong aurora later in winter, unfortunately it was raining here all night long. Current strong solar activity met with a perfect weather. Honestly, I never expected to see such strong aurora over here!

I started early, when it got at least little dark. This time I knew I need to do some test shots to notice weak aurora, its often invisible for eyes. And voila, there it was! Very weak pink glow, slowly getting stronger. I made couple photos, but it was not a really good spot, so I jumped into a car and moved on the nearby hill with a good view.

I was honestly shocked when I left the car about 10 minutes later, the sky turned completely red. I made couple still shots and set the camera to time lapse. The show diminished about 20 minutes later, so I decided to move to other place. Original plan was to go home, but meanwhile the red colors changed to zoned aurora with purple-pink upper layer and green bottom. So I had to do a wide panorama, of course.

Then I moved back home, but meanwhile the activity got even stronger then before. I made couple shots around the house and moved back to the fields with no lights in sight, where I made another stills and two time lapse sessions.

In the end, it was almost 4 hours chase, then I really had to stop and get some sleep. I have a stockpile of photos, which needs to be properly processed, stitch panoramas, export time lapse videos. This article is just a preview, more to come, with technical details how I did it.

Northern Lights

I did not expect to see northern lights in my home country, as they seldom appear that much to the south. However, in the evening on 5. November was quite strong aurora reported even from Croatia! Such strong auroral activity was not seen here in decades.

Unfortunately for me, the main event exactly overlapped with rain in my area. I managed to catch a little purple color between two showers, when there was only partly cloudy for a few minutes. The rain ceased quite late when remnants of purple haze were barely visible by naked eye. I used fully open aperture at f4, high ISO at 3200, and 30 seconds exposure time.

Anyway, it was fun to try. There are weak auroras occurring few times per year, mostly visible only on long exposures and invisible for naked eye. If you want to try, there is a nice aurora prediction tool by NOAA.

Night Storm

Despite the fact that I did a lot of lightning photos, I’m not an active stormchaser. I’m a passive storm photographer and I simply wait for random storms coming to me. Thus I very rarely see the storm coming from the distance.

This time I got lucky and there was a very active thunderstorm, nicely visible from the distance (about 30 kilometers). The final photo is a stack of 5 photos per 60 seconds = 5 minutes exposure in total.
