Meeting transcript video
- Intro – Randy Enkin
- We still don’t have approval to hold monthly meetings at UVic, so speakers will continue to present at Astronomy Cafe
- Learning Astrophotography – Reg Dunkley
- Dec 6th Astro Cafe presentation by Ron Fisher on his adventures learning astrophotography – thanks Ron!
- Victoria Centre Observatory can help members to start taking astrophotos using our centre’s gear once the VCO reopens – soon now. Bring your own dSLR to use on our Takahashi refractor, or use our 61 mpix mono astro camera on our OGS Ritchey–Chrétien telescope.
- Far Side Amateur Astronomers Observing a Supernova – Reg Dunkley
- Time-resolved 2-million-year-old supernova activity discovered in Earth’s microfossil record – by UVic grad Shawn Bishop et. al., and refer to Reg’s article in Oct 2016 issue of our SkyNews (pdf)
- Star formation near the Sun is driven by expansion of the Local Bubble by Catherine Zucker, et. al.

- How a supernova happens
- Neutrino flux hitting Earth predicts a new supernova (about 18 hours ahead of time)
- Neutron stars, cosmic rays, Iron 60, Gamma ray bursts
