An Evening Conjunction

e Moon, Venus and Aldebaran
The Moon, Venus and Aldebaran join up for an evening conjunction

This evening will feature a a pretty set of planets and the Moon low in the sunset. Mercury, Mars, and a thin crescent Moon will be visible above the glow of the setting Sun.

The Moon will be a very thin sliver, a mere 4% illuminated. Look 7° above the Moon for Mars. Mercury will be harder to spot, about
7° below the Moon, closer to the sunset and a little north (to the right).

One Year Ago…

On June 3rd, 2018 Deb and I flew over the ongoing eruption of Kilauea. It seems so long ago, it seems like yesterday.

Fissure 8 Lava Fountain
The lava fountain at fissure 8 in Leilani Estates throwing lava hundreds of feet in the air on June 3rd, 2018

We looked down on a broad flow front, over a mile wide. The flow burning through orchid farms and papaya orchards, destruction that was painful to watch.

We looked down on a lava fountain hundreds of feet high. Fissure 8 was supplying a river of lava that spelled doom for Kapoho Bay and the beautiful tidepools at Waiʻopae.

A year later the lava is still cooling and the community is still rebuilding. Kilauea is quiet with no lava on the surface anywhere. We wonder where the next eruption will be.

Mercury at Superior Conjunction

Today Mercury is passing through superior conjunction, passing around the far side of the Sun as seen from our earthbound vantage point. This fast moving planet will reappear in the sunset in about a week, rising towards maximum elongation on June 23rd.

The June apparition will be the best of the year with the planet reaching over 25° from the Sun. The October apparition will be quite good as well at over 24°.
