Hi Bill,
Great to see your spectrum of this Ursid. We measured its Vg to be 33.6 km/s (medium speed) and the IAU MDC lists the Ursids’ parent to be comet 8P/Tuttle – why does that remind me of Benny Hill? 🙂
It’s a Jupiter-family comet with a period of 13 years. Well worth reading up about this interesting comet which can make relatively close approaches to Earth.
I’ll check if we got multi-station captures at the times you’ve listed and I’ll reply offline.
Cheers,
Alex.
