OO-GPS doing circles during the night of 18/02-19/02

Hi,
First of all probably not the correct place to post this, but your twitter guy send me to this forum so yeah here it goes:

On Saturday night I was unable to sleep because of a little plane circling( actually it made its U-turn just above my house) @3700ft. I'm not here to rage about the noise, just super curious what he was doing there.
So I tweeted some guys who I thought could help: https://twitter.com/JeremyCoppey/status ... 3658616832
Also contacted the firm: http://www.eurosense.com but nobody could help.

So guys do you have any idea's?
So some plane details I already found:

For when the flighradar24 url does not have the data anymore:

Thanks

I guess that all this Tweeting around, won't get you any more answers than what you have seen/heard/FR24-ed: aerial sensing at night over the 'Pajottenland' area
And what type of sensors they used, IR, or LIDAR, or... and what specific target they had in 'Pajottenland', I guess, only Eurosense knows...
Personally I find all those Cessna big piston twins, pretty noisy. So buzzing around for 4 hours during nighttime at 3700ft, must not have made many friend on the ground

I agree with you it makes some noise certainly when they tend to just turn over your head at 3700ft (they say 2700ft, )
But hey, it worth it, it's for the climate

Don't forget to complain at your municipality instead of Eurosense as they operate this mission on behalf of...

[DIBO]

No reason to complain, with some good communication (preferably beforehand) you can maintain good neighbourship and local community relations, even when doing activities which temporarily cause some nuisance...
Regarding Eurosense, well yes, they are responsible for the equipment they fly, and there are more silent aircraft than the 404's they use. But as they rarely stay that low and that long in the same region, and even more rarely at night, we shouldn't overreact either.
