2017 Week 7: (February 12-18)

This upcoming week has some significant events that you don’t want to miss.  Starting on Monday the zodiacal light should be visible from dark skies for the next several weeks.  Look to the western skies soon after sunset and see if you can see a conical light emanating from the horizon.  Mars and Venus are lined up to be inside this cone.  We are going to take a trip outside of town to some dark skies to see if we can see it this year.  For more information about Zodiacal Light please see the post from last Saturday linked below.

Zodiacal Light

Another exciting thing happening this week is associated with the planet Venus.  Venus will be at its greatest brilliancy Thursday evening and Friday morning.  Even though it is a waning crescent, approximately one-third illuminated, it will be large and bright.  If you are at a dark site, you may be able to see your shadow cast across the ground from the light of Venus.

**Don't forget the penumbral lunar eclipse tonight!  At Moon rise (5:44pm) the Moon will appear slightly shaded as it transits through the outer shadow of the Earth!  Full details linked below.**

Penumbral Lunar Eclipse Information

As typical in most months, Jupiter will be aligned with the Moon Wednesday evening at a separation of 3°.  This is close enough to fit in a typical binocular field of view.  The Last Quarter Moon will appear on Saturday on its way to fading out to start a new lunar cycle.  The full astronomical schedule for next week is below.

Date Event
Feb 13 Zodiacal Light strongly visible in western sky for two weeks
Feb 15 Jupiter 3°S of Moon
Feb 17 Jupiter at Aphelion
Feb 17 Venus at greatest brilliancy
Feb 18 Last Quarter
Feb 18 Moon at Apogee
Feb 18 Asteroid Irene at opposition

Interestingly, the asteroid Irene will be at opposition and at its brightest.  However, it will be magnitude 9.0 and you’ll be lucky to catch it in a pair of nice binoculars.  It will be more than 3° from the naked eye Zeta Leonis in the constellation Leo.  Attempting a telescope find will be difficult, however if you wish to try your luck a star chart is provided below with a binocular field of view circled.

Irene Star Chart
The weather is starting to warm up and the skies are clearing.  There will be plenty of opportunities to look up and see some of your favourite planets!  Look for Jupiter moving to the southwestern sky just before sunrise!
