Star Calendar – October 2015

Star Calendar

October 2015

Star Calendar Planets:

Moon moves through the stars, eastward, at its own diameter every hour, or, 13 degrees per day, or, one season per week — as noted below.

Mercury is pretty bright now and is at greatest elongation mid-month. Those with a clear view to the east might pick him out due east at about 5:00AM

Venus is in her afterglow after her maximum brilliance last month. She is still at a large angle from the Sun and can be seen during the daytime with a little care. Look about 45 degrees (half a right angle) ahead of (right of) the Sun and patiently let the eyes linger, wandering in slowly larger circles around the chosen spot in the sky. Don’t look too hard or dart around too much. Once you see Venus you’ll wonder why it seemed so impossibly invisible to begin with — it just stands there sharp and bright; but if you go out another time it’s just as hard to find again!

Sun no longer gets high enough in our sky to create Vitamin D in our skin. The rule of thumb is that if your shadow is longer than you are tall, you are not getting the rays that stimulate that beneficial nutrient. The native northern-clime peoples make up for this with a very fatty acid (fish oil) diet. Those that shower daily might consider skipping the soap unless it’s actually needed; Vitamin D is an oil kept in your skin and it washes off with soap! UVA lights will give a suntan — but it is UVB or UVC that is needed to make Vitamin D.

Mars should now be visible, east in morning nautical twilight (around 5:00AM). As October opens he will be below Regulus and slightly dimmer. Venus stands higher, very bright, and Jupiter below, quite bright as well. On the 9th the Moon will stand just to the right; on the 18th Jupiter will stand very close by and he will finally have a sojourn with Venus on Nov.2nd.

Jupiter is the brightest object beneath Venus in the morning.

Saturn is low in the SW these evenings. He shuffles into Scorpius on the 16th, accompanied over the threshold by a crescent young Moon that night. They are SW at about 6:00PM
