Star Calendar – March 2017

Star Calendar

March 2017

 

Star Calendar Planets:

Moon cycles determine, or play a role in, some calendars such as the Islamic and Hebrew. The Islamic year is strictly lunar while the Hebrew is a hybrid luni-solar that inserts extra months so that the seasons don’t drift too far. The Hebrew year begins with Nissan. It commemorates the emancipation of the Jewish people from bondage in Egypt (Exodus) and Passover (whilst Rosh Hashanah commemorates the birth of the World). The Crucifixion is recorded in relationship to Passover and Easter is placed in such a way as to respect this correspondence. This year Nissan begins at sundown on the 27th of March, 15 Nissan (beginning of Passover) on the evening of April 11, and Easter on April 12. This year both Western and Eastern traditions correspond to the same day.

Mercury crosses the far side of the Sun and then appears already on the 18th next to Venus in evening.

Venus is now nearer to Earth than to the Sun as she streaks from evening to morning. On the 25th Venus is more than twice as far from the Sun than from the Earth – the ratio being just about 5:2. Venus begins the month stationary to the stars, then rapidly departs and crosses the nearside of the Sun by the 25th. She will be seen in the pre-dawn east already in early April.

Sun is rapidly increasing its presence in the sky by adding almost 3 minutes of daylight to each day. Of course, as we gain an abundance of daylight – the Govt. must naturally order us to start “saving” it.

Mars is seen to the right of the crescent Moon on the evenings of the 1st and again on the 30th.

Jupiter begins March near Spica and we can watch him move, retrograde, back away from Spica as the month proceeds. The pair rises about two hours after sunset and is joined by the Moon on the 14th.

Saturn slows his slow shuffle – that is so slow that he lingers in each seasonal quarter of the sky for over 7 years.

25 Venus streaks across near side of Sun; inferior conjunction

27-28 New Moon begins Hebrew month of Nisan – that places Passover and Easter

31 Sunrise/set in Spring Valley at 6:41/19:20 (12h39m daylight)
      Day number 90; nearly ¼ of the year has passed
      Enjoying the additional 1 hour and 22 minutes of daylight?

Star Calendar – February 2017

Star Calendar

February 2017

Star Calendar Planets:

Moon crosses the ecliptic (Moon node) when near syzygy with the Sun twice this month. Neither eclipse will be noticeable to us though. The Full Moon will rise in the penumbra of Earth’s shadow, will only be slightly less bright – but no hard shadow edge. At New Moon the Moon shadow’s tip will not quite reach the Earth’s surface such that the Sun will appear as a ring of light – for those along a path in the southern hemisphere.

Mercury drops out of morning sky to cross far side of Sun on March 7th.

Venus is a waning crescent that grows taller by the day. She shines to cover the largest portion of our sky on the 17th but is nearer, and brightest, on the following day. Thereafter her wane out-does her drawing nearer – but she remains sensational. Last month I saw my shadow cast by Venus; walking down a snow-covered lane (before the Moonrise) with Venus at my back.

Sun is halfway from winter solstice to vernal equinox and crosses the sky as it does in November. Astronomically winter is half over, climatically – by hysteresis of heat absorption – not so. Oh well.

Mars cruises Pisces this month as he sets out on his super-circum-zodiacal tour before making his next loop in 2018.

Jupiter pauses to begin this year’s loop in Virgo that will culminate with opposition in April.

Saturn enters the region of his next loop, vacillating between Ophiucus and Saggitarius.
