This was an exclusive launch, the idokep.hu (communal, informative private weather service) guys launched a special sonde with cameras attached to a styrofoam sphere, with GPS trackers, to film the thunderstorms crossing Hungary.

Before the launch, the guys emailed me, to track the sonde, and send back the weather data I've received with my yagi. Then, with SZGY, we decided, to race with them, and try to get the sonde. After the burst, we've got into the car, and approached the scene, where the signal was the strongest. Fortunately, the Budapest sonde wasn't already launched, just minutes after the final location.

The sonde landed on the stubble, and it was easy to locate it, because of the big white sphere laying on the ground. We didn't have even to turn on the SDR with the yagi. Picked up the stuff, and went back to the car. In approx 15 minutes, a guy from the időkép team came, said hello to each other, talked a bit, and went home safely.

We even couldn't think what would be happened and how we would find the equipment if the sonde would land on the opposite sunflower field

Videos from the GoPro's will be published soon!

I will enjoy to video from that cameras.

Asked, and only darkness and some foggy lightnings were filmed through the closed clouds.

I expected better results from GoPro cams

Naburko napísal:I expected better results from GoPro cams

They made better films daytime. Without light, it's too hard to produce sharp and bright images...

Here is similar project, this time sending camera closer to the aurora: http://nightcrewlabs.com/projects/alaska/aurora/
They had far better camera (A7s, F1.4 lens) and it looked quite good (main issue was constant rotation of the payload).
I think GoPro is simply not good enough to give you usable video under such conditions, but it's cheap. A7s is not exactly cheap camera to send to atmosphere and possibly never see again... but you can film at ISO 25600 and it still looks usable in 1080p, which is incredible. Especially when paired with fast lens, it's like a night vision... Would be really cool to film say shelf cloud in the night, from above, lit by a moonlight

Nice, but a bit more expensive solution...
