Yes, the article is in the September 2012 issue of Sky & Telescope. While there is data from the SonotaCo network in Japan, there is additional data from the CAMS network in California. This is a NASA supported programme and it looks like they've developed their own capture and analysis software (ie they don't use the UFO Suite).
Would be interesting to understand the rationale behind this decision as their hardware configuration (Watec 902H and 12mm f1.2 lens) is supported...
Hi, There were a couple of presentations I went to at the ACM in Japan earlier in the year about the CAMS network. Very interesting but it seemed to me they were, in their own style, carrying out similar observations that SonotaCo has been doing for a decade. They were doing it with a large concentration of cameras at the observing locations and this seems to have produced results quickly. On the equipment front they were asked about this and it seems to been an availability issue. I took it to mean that this is what they could get with the money. The CAMS group are giving a talk at the IMC conference on La Palma in a couple of weeks called "First Year Results from the CAMS System". I'm going to that and am looking forward to the event immensely.
Regarding the magnitude of meteors for spectra, that's quite difficult to define and it depends heavily on the general observing conditons. However a rule of thumb that is quoted in some books is at least 3 magnitudes brighter than the detction level. So you're looking at minus something at least. The few I've caught I would say have been brighter than -3 but that is nothing more than an educated guess as the meteor itself has been outside the frame in all cases except one!

Wish I could get the time off work to attend - maybe next time
