Star Calendar – June, 2015

Star Calendar

June 2015

Star Calendar Planets:

Moon opens the month large in phase and casting long shadows – sometimes being completely obscured by foliage and other horizon clutter. The low-running Full Moon of June contrasts with the height of the Sun. Harken back to the December Full Moon that runs so high, so long, and casts short shadows.

Mercury resumes direct motion against the stars on the 11th and makes a feeble but improving morning appearance at an inconveniently early hour. Although its greatest angle from the Sun occurs on the 24th, circumstances improve after this as the trailing ecliptic makes a steeper cut against the horizon towards July. The determined, stalwart observer with an excellent view to the ENE, might begin looking on the 27th – at about 3:15 AM.

Venus continues to brighten and achieves 1/8 of a circle angular distance from the evening Sun. Even though her phase diminishes she continues to brighten because she gets so much closer (larger angular area) to us. The month opens with an alignment with the heads of the Twins, culminates with a series of stunning triangles with Jupiter and the Moon, and closes with a striking close encounter with Jupiter.

Sun reaches its maximum distance from the celestial equator (declination) during lunch on the 21st and then begins to descend toward the equator again. The moment of transition is called the solstice or “Sun-standing”. Astronomically this is the mid-point of summer. Weather-wise, like with your frypan, the midpoint of the cycle of heating and cooling lags behind the application of flame. Our summer weather is largely hangover heat.

Mars sneaks behind the Sun on the 14th. After a covert encounter with the Twins he will next appear some morning in August as he enters Cancer.

Jupiter continues a steadfast march towards Regulus and crosses a (rather arbitrary) boundary into Leo – but it will be seen increasingly as a mere embellishment to Venus as she sweeps him up late this month. We’re in for some beautiful evening configurations.

Saturn takes 28 years to progress through the zodiac and is now sitting where does the Sun in late November. Saturn will not be seen above (north of) the celestial equator until 2026.
