Explore the Moon (Binocular) - March 6, 2017
Asterisms: Winter Circle, Winter Triangle
Time: 5:30 PM - 9:30 PM
Instrument: Visual + Binoculars (10x30 IS + 15x70)
Magnification: x10 + x15
Temperature: -6° C
Clear skies; little if any breeze. This session began with looking for objects in the RASC Explore the Moon (binocular) program. I then went looking for constellations and the conjunction.
At 6:45 PM, Orion couldn't be easily seen because of the brightness of the Moon.
At 8:15 PM, it was very visible. All the stars of the Circle were clearly and easily viewed - Capella, Aldebaran, Rigel, Sirius, Procyon, Pollux, Castor.
NOTE: The night before, I could only see Pollux, Capella, Aldebaran and Sirius due to the thin cloud cover and the First Quarter Moon.
Time: 9:16 PM
Dave Chapman had emailed the Halifax Centre Discussion List to remind us there was also a Winter Triangle - Procyon, Sirius & Betelgeuse. Tonight this asterism appeared to be an equilateral triangle.
