Such sad news.
I only met him a couple of times, but when I did he was so generous with his time and supportive of my daft ideas.
He will be greatly missed by all who knew him in the world of astronomy.
RIP Ron
Excellent results Bill.
I’ve been thinking for some time that we should try again to get some spectra to supplement our videos here at Clanfield. I tried a few years back but gave up for various reasons. Do you have any documentation of your latest capture setup that would help a beginner get started ? What is the plastic grating you are raving about ?
Cheers
Steve
I just checked back and I do have this email from 1st August – I will be voting asap. Actually I got the email twice! Once to me as an individual member and once to me as the registered contact for my affiliated society.
Can we please clarify if affiliated societies have a (single) vote – I didn’t think they did

I have not personally tried this but here at Hampshire Astronomical Group we already offer “Observation of Transiting Exoplanet” as a project option to University of Portsmouth final year students, so giving the subject a higher profile within the BAA sounds like an excellent idea.

Fascinating comparison, Bill. Very clearly shows the effect of increasing KE. Will ask my spectroscopy expert for his opinion on the bit below 4000A.

One other thing to watch out for, Eliot, is hard disk space. At Clanfield we took the decision to have a dedicated PC per camera and each PC has either a 1TB or 2TB drive. This isn’t strictly necessary if you regularly check your captures and delete false clips – spiders and storms in particular can cause hundreds of false clips per night and if you aren’t careful, you could quickly start running out of space. We also copy our data to an archive drive so that at the end of each year we can delete the oldest records (but still have access to them)

Only later did we look at our Radio detection system (after Michael O’Connell of Basingstoke reported that he had captured something)….Our trace is here
I am still trying to understand how to interpret these traces, but even to my eye what is clear is there was a very rapid increase in frequency as the meteoroid hit the atmosphere. The frequency suddenly broadened into a 50Hz bandspread, peaking briefly (at the explosion?) at more than 150 Hz. The 50 hz band persisted for a further 5 seconds or so, before the trace ends with two to three seconds of ‘top notes’. In total, the event lasted around 10 seconds. I’m sure there are experts out there who can explain what all that means !
