Star Calendar Planets:
Moon will now be Full near the ends of the months for a while. This month will have two occasions of perigee occurring within 24 hours of syzygy; look for Spring Tide inundations on the 1st and 30th. New Moon is timed for ideal Perseid meteor viewing this year. I plan to look for them (from Breezy Hill, Springfield, VT) during the 80th “Stellafane” convention. RIP Carl Breuning (I’ll never forget viewing Mars with the 12” Porter Turret; sharp and clear through solid cloud-cover – this surprised us both!).
Mercury slips into the evening sky as Venus departs. On the 6th and 7th, in the glare of evening twilight, there is a close tussle with Jupiter and Regulus but we may hope for a better view on the 16th, to the right of a standing crescent Moon.
Venus takes a bow and swiftly crosses the nearside of the Sun this month. Look for a liaison with Mars, beginning as the Full Moon sets on the morning of the 29th with RA conjunction, but more pleasing to the eye in the first week of September.
Sun is halfway from solstice to equinox on the 1st; “Lammas” (Loaf-Mass) is a cross-quarter harvest festival.
Mars will creep into view for early risers during the middle of this month. Diehards might look to the left of the crescent Moon at 4-4:15 AM on the 13th. Mars will then appear in line with and below Gemini’s Pollux and Castor.
Jupiter takes a passage behind the Sun, conjunct on the 26th.
Saturn finishes a long retrograde period on the 2nd and is at quadrature (90 degrees from Sun) on the 21st. Saturn is now strictly an “evening star” as it sets before midnight and appears in the evening beyond culmination.
Pluto: the latest astronomical centerfold, and an intriguing one it is. The space-camera is traveling at truly meteoric speed. Consider: my 33-yr-old car has traveled about 400,000 miles, or just over 2 light-seconds (“to the Moon” – and nearly back); Pluto (near the Teapot) is about 5½ light-hours away, or 9,900 times that distance.
