Meteor Network
« on: Sep 08, 2021, 17:28:01 »
About a month ago, while the Perseids were putting on their annual show, I placed a bunch of orders for bits of kit to put together as a meteor camera. The image collection device is a Sony IMX291 camera with a 4mm lens, and the processing device is a Pi 4. It took a while for the bits to arrive, and a while longer for me to put them all together and get them working. I finally attached the camera to the side of my house last weekend, and the system is now calibrated and ready to run.

Most of the information needed to set the thing up is on the Gloobal Meteor Network wiki ( https://globalmeteornetwork.org/wiki/index.php?title=Main_Page ). There are also pointers on the UK Meteor Network website ( https://ukmeteornetwork.co.uk/ ).

I've a clear view out towards the north, and this is the coverage map for my camera.



The largest area is for meteors at about 100 kms altitude. The other two areas are for meteors at around 70 kms and 25 kms altitude. Most meteors won't get much lower than 70 kms.

On Monday night the system spotted 122 events, and last night it spotted 195, so there's quite a lot dropping out of the sky at the moment. Here's my pick of the night:



Of course, the forecast for most of the rest of the week is not so great, and I suspect my camera weatherproofing may get a bit of testing, but the main point of the system is that it mostly gets on with the observing by itself, without needing too much intervention, and if the sky clears in the early hours the camera will be there to look out for meteors.

That is really cool.  Check this guy out in near Minsk:  https://www.astrobin.com/users/Astronominsk/
I wonder if he is part of a wider European network.

See for example this one:

Couldn't find a corresponding station this GMN list ( http://istrastream.com/rms-gmn/ ), but there are multiple meteor monitoring networks, so he may belong to a different one, or his camera may not have reported in for a while.

It looks like a great project Rick and really interesting.  It's the kind of thing I really should attach to my observatory.

Not a lot of work involved, but a few minor gotchas to be avoided, especially with the camera hardware. I think my total came in at under 200 quid,  but I did re-purpose one or two things. Some folk have put the entire set-up into a camera housing that just needs a PoE cable, but the Pi 4 gets quite warm...

A great project, Rick.  Look forward to some updates soon!

Thanks also for the 'Minsk' link Roberto ~ some cracking Moon pictures amongst his portfolio.

Best

Hugh

Not quite under 200, but plenty of change from 250, partly because I ended up getting a 4GB Pi 4 and a fast 128GB SD card rather than the 2GB Pi 4 and 64GB SD card that's the present minimum recommendation.

I've been impressed by the way the system can grab data through holes in the clouds. Each morning it produces a stack of the frames on which it thinks there are meteors it has managed to calibrate against the starry background. Last night was the first night it failed to see any. I'm not totally convinced by the meteors it spotted on some nights, but it has certainly picked out one or two through holes in the clouds.
