Martin Kessel from Stoke on Trent has been in touch to report that he too captured this event on video. Martin writes “My old camera started working a couple of days ago, just in time to record this last night. Meteor heading west over the south end of Stoke on Trent, shines through the cloud (all stars covered) and goes well past the zenith at quite a high speed.“
Martin’s video can be viewed here: http://www.youtube.com/watch?v=Y3bMaqEjobI&feature=youtu.be

Hi All,
Detected from Ravensmoor too. Combining data with that from Alex and Nick, a provisional analysis suggests that the original orbit of the meteoroid was of a low inclination (5.4 degrees) with an aphelion in the vicinity of the asteroid belt.
A sporadic, the absolute magnitude is -1.9 though this may be an underestimate as a consequence of the twilight conditions reducing the number of stars available for comparison.
Suspect this was detected by others so more detail to follow.
Best regards

Hi James,
Using a Watec 902H (the earlier, lower sensitivity model of Nick’s camera) in conjunction with a 8mm f0.8 lens it’s possible to obtain a stellar limiting magnitude of better than +5.5 on a clear, moonless night at 25 frames per second. Meteor detection is determined by a number of factors not least of which is the apparant brightness of the meteor. In addition however, the UFO Capture software has a number of configurable “trigger” settings which determine the circumstances under which a recording will be made.
These trigger values can be set to a high sensitivity whereby the slightlest movement within the FOV will trigger a recording. This is great for fainter meteors but the downside is that it also results in many false captures (due to birds, bats, insects, falling leaves, aircraft, satellites etc, etc). Lowering trigger sensitivity reduces the the number of false captures but also reduces the number of faint meteors recorded.
My system has what I regard to be quite sensitive trigger values and records meteors down to 3rd magnitude.
Further details of our systems and links to our papers (which go into even more detail) are available on the NEMETODE website.
Best regards

Very nice work indeed Nick … the orthogonal observing angle between your systems and those of John / Russ in Chichester are proving very productive – really looking forward to the data these deployments will produce. The Chicjester video and orbit plots are available at http://nemetode.org/
