Citizen Science - Crater Timings During Lunar Eclipse
  • Intro – Jeff Pivnick
  • Planetary Alignment on Feb 28th – reports from David Lee, Vince Geisler, Brock Johnston, Brian Barber, Alex Schmid
    • VCO turned out to be a good location for our group of 14 members
    • Venus – 6:30pm
    • Mercury (not visual, but photos)
    • Saturn
    • Neptune (photo only)
    • Jupiter
    • VCO’s Takahashi visual observations – Saturn, Uranus, Jupiter with Callisto’s shadow and Great Red Spot
    • Photos
      • 16″ – Jupiter with Callisto’s shadow and Great Red Spot – Brock Johnston
      • Venus & Mercury – Steve Martin and David Lee
      • Saturn and Venus – Wyman Lee
      • Venus, Uranus, Jupiter, Moon, Orion Nebula and Andromeda Galaxy – Sidewalk Astronomy at Cattle Point – Vince Geisler
      • Venus, Jupiter and the Moon, and Andromeda Galaxy later on – Sidewalk Astronomy at Mount Tolmie – Brian Barber and Alex Schmid
      • RASC Newsletter Highlights – included an item by Randy Enkin
  • Citizen Science – Crater Timings During Lunar Eclipse – 2006 – Randy Enkin
    • Visual project to record timing data
    • Sky & Telescope – expected timing for various lunar features – ingress and egress
    • Need an accurate audio time readings – Ticking Clock or equivalent app
    • Analysis of lunar crater timings (from 1842) – a database by David Herald and Roger Sinnott
    • Victoria Centre members are encouraged to observe timings for this lunar eclipse and the next one
    • Randy will be at the Centre of the Universe for this lunar eclipse event
    • Centre of the Universe will send a go/no go message to attendees at midnight tonight – Lauri Roche
    • Weather forecast from Reg Dunkley
      • Environment Canada forecast indicates quite thick cloud cover
      • “Ragged” cloud, so it may not be a total loss
  • The Moon, a Meteorite, Monk and Me – Leslie Welch
    • Apollo Moon Landings – “Magnificent Desolation” Buzz Aldrin
    • Transient Lunar Phenomena (TLP) – various types of short-lived light, dark and color features/events
    • Crater Alphonsus – reported by Kozyrev 1958
    • Monks Record a TLP – report appears in The Barmaid’s Brain – Jay Ingram
    • Giordano Bruno bright crater discussed by Jack B. Hartung in 1976
      • Bruno is on the far side of the Moon – barely, but in the Libration Zone
      • “Ringing” lunar oscillations are measured at 1.8 arc seconds – could be caused by the Bruno impact
      • Paul Withers 2001 paper
      • Luna 24 – Russian sample return mission
    • Bright flashes on the Moon have been observed and photographed recently – likely TLPs kicking up dust that is briefly illuminated by sunlight
  • Artemis II and Wet Rehearsal – Jeff Pivnick
    • Comparing the current SLS rocket versus the previous Saturn V
    • Review of rocket stages, fuel used and umbilical connections
    • Failures during two wet rehearsals on Feb 2 and 19
    • Fuel loading and unloading
    • Problems and benefits with using cryogenic fuel
  • Artemis Mission Changes – Chris Gainor
    • Artemis II will fly as announced this year
    • Artemis III – 2027 in Earth orbit instead of landing on the Moon
      • Depends on refuelling in space
      • Huge number of ambitious goals
      • Landers from Blue Origin and SpaceX being considered
    • Artemis IV – first lunar landing in 2028
    • Annual lunar landings starting in 2028
    • The Lunar Gateway is now in question
