Hi Bill,

Fascinating stuff.

You also have additional camera alignment options with David Anderson and Denis Buczynski.

I recorded 103 Quadrantids on Jan 3/4, but in addition there were 18 meteors that UFO Analyser categorised as J5_daD (December alpha Draconids). This shower has been confirmed by SonotaCo data, but its radiant lies close to that of the Quadrantids, being active at a similar time of year and with similar Vg.
I always regard shower membership from single-station work as provisional. A single-station meteor could be assigned J5_daD membership, then later identified as a Quadrantid from dual- or multi-station analysis.
Is it possible that you have a mixture of Quadrantid and December alpha Draconid spectra?
