NEMETODE is a network of cameras based in the British Isles that monitor the night sky for meteors ("shooting stars"). Through the use of triangulation and timing the network is able to determine the actual trajectory and velocity of the meteoroids as they pass through the Earth's atmosphere. From this we are able to determine specific characteristics such as the radiant (that point in the sky from which each meteor appears to originate), how the position of this radiant varies with time and the parameters of the original solar orbit of the meteoroid (before the earth got in the way). We analyse our own data as we find this is an excellent feedback mechanism that deepens our understanding of the subject and enables us to optimise our detection capabilities. Our results are published in peer reviewed journals such as the Journal of the British Astronomical Association and WGN, the Journal of the International Meteor Organisation. Having completed our analysis, our data is uploaded to EDMOND for consolidation with other European groups. While we have excellent coverage over certain parts of the British Isles, there are still many gaps so please get in touch if you are interested in joining the group.

09th November 2012: Northern Taurid Fireball: Well we did warn you that things were getting busy! This spectacular magnitude -6.5 flaring fireball occurred on 08th November 2012 at 23:54:20 GMT. Videos, details and an analysis are available here.


06th November 2012: Bright Southern Taurid: Things tend to get busy at this time of year (and we're not talking about Christmas Shopping) as northern hemisphere observers enjoy enhanced activity from multiple showers. From Leeds this event passed through Orion on 06th November 2012 at 01:02:41 GMT. Videos, details and an analysis are available here.


02nd November 2012: Bright Sporadic Meteor: Has been a while since we reported anything of note ... this one occurred on 01st November 2012 at 18:35:37 GMT and our vew of this one even includes satellite debris resulting from an on orbit collision (some satellites were harmed prior to the making of this video). Videos, details and an analysis are available here.


10th August 2012: Bright Perseid Meteor: Last night we detected a rather bright Perseid meteor on 09th August 2012 at 21:32:49 GMT / 22:32:49 BST. Not quite a fireball but bright enough to prompt members of the public to report their sightings. We even have a flock of birds in the capture (no animals were harmed in the making of this video) ... details and an analysis are available here.
