I directed my cam due North, Alt 60deg on the 27th to see what the fov was like. The sky was quite clear. Between the hours of 21.30pm and 5.00am UTC I picked up 55 meteors. Most were quite small and faint with my 2.6mm lens, but a few were much brighter. They came from all directions but clearly there were some that seemed to originate from the same source. I can't check them yet as I don't have the software but that will be purchased very soon.
It seems that my final capture may have been a fireball. Time on the avi is 04.30.24. It originated from the direction of Dubhe in Ursa Major, and my cam captured it as it passed Polaris. My location is Basingstoke, Hampshire. I wondered if anyone else may have caught it on cam. It doesn't look as impressive in a 2.6mm lens as it would have at a longer focal length, but it was still very bright. I don't know yet how to post a video on here so I can't show you yet. My avi file is 35MB. If someone can advise on how to compress it to a manageable size, or what is the best way to show a video here, I'd appreciate it.

Hi Allan, Will check my captures from Ravensmoor tonight when I get back from work to see if I also caught the bright meteor you mention. There are instructions relating to video compression for Windows XP and Windows 7 at the bottom of the "Hints & Tips" section of nemetode.org/analysis%20techniques.htmHope this helps Best regards William

Hi All,
Just quickly checked the PC before leaving for work. 0104UT +/- (time not accurate on old machine) this morning 29th Oct, on my SE camera. Didn't get the meteor in frame but the spectrum was saturated for almost it's full length. It must have been very bright! Very distinct 5577nm train. I'll post some pics this evening.
cheers, Bill.

Hi William. I made a mistake on the time of the meteor. (I forgot we had turned the clocks back an hour, so the time on my comp is actually UT now) Anyway, the time of the meteor in question would be 053024. Here is the compressed video at half speed. video

Hi Allan / Bill,
Have checked Ravensmoor captures for the morning of the 28th at 05:30:24 BST / 04:30:24 GMT and for the morning of the 29th at or around 01:04 GMT but alas nothing captured at those times ... hopefully others had more success.
Best regards
William

Hi, This one was nice! Short duration cf the Taurid but better line resolution. A goodly number of real lines and a very interesting one at 615.7nm from Oxygen, this might be from the SiO matrix itself rather than atmospheric. (Further to our last telephone conversation William, toe to toe with the pros...? ) Attachments:

Hi Bill, Very nice capture indeed, clearly shows the capability of your system! >Further to our last telephone conversation William, toe to toe with the pros...? Definitely - hope you're working on a paper

Hi all, It's taken me a bit longer to check my captures because I didn't notice (at first) that there's two different events reported in this thread. It looks like my Leeds_SE camera might have recorded the start of the 20141028_053024 meteor, but my timing is UTC. UFO_A estimated it to be a mag 0.9 sporadic, but of course this is its initial stage. (Pic attached) My Leeds_NW camera recorded the second meteor at 20141029_010418. UFO_A suggests it was a Iw_OMO (October Monocerotid), although it is also well aligned with the Orionids radiant. The estimated mag was -3.6, but with few reference stars (cloudy sky) this has an error of 2.5 mags. (Pic attached) Bill - that's a cracking spectrum! I had a few bright meteors that night on Leeds_NW 20141029_010211 -2.6 20141029_010418 -3.6 20141029_022322 -1.3 20141029_025151 -1.8 20141029_052030 -1.7 Cheers, Alex.

Thanks Alex. The timing you have is correct. Initially I deducted an hour, but then remembered that my comp would have changed back to UT at the weekend.

Hi, I could believe your 010418 is the same one. The old pc's I use aren't networked or online so I have to do a manual time check. The meteor was below the FOV (given the dispersion direction) so it might've been ~30 deg alt from here. Yep, I think it's a possibility.... Cheers, Bill.

Hi, To be "scientific" here's the response corrected graph.... cheers, Bill. Attachments:
