Tomorrow we have a Blue Moon, a full moon. While there is no color change, the name of a color refers more to its rarity. You won’t see anything unusual when you look up this weekend.

A Blue Moon occurs on the second full moon of a month. We had a full moon at the start of October and this one comes on the last day of the month Halloween. What is truly rare is that this one falls on Halloween night, when little gobblins and witches are roaming. In fact, if you do the math every time the moon is full on Halloween Night, it is a Blue Moon.

On Wednesday night the gibbous moon and the bright red planet Mars start the evening low in the southeastern sky.

The annual Orionid meteor shower takes place on Wednesday morning after midnight.

One of the great features of autumn nights is high overhead when the Milky Way, our galaxy, crosses the sky. You can’t miss it on a moonless night.

The red planet Mars is a spectacle rising in the eastern sky soon after sunset. A brighter Mars will not be visible until the year 2035, and for many this may be a first time to spot the planet.

Mars reaches opposition in mid-October and the show is available all month. Opposition happens about every two years, but this one is best placed for our latitude. Mars was closer two years ago but it was also close to the southern horizon.

Tonight’s gibbous moon appears right underneath the bright planet Saturn.

An orange sun and skies in the morning and late afternoon aren’t the only changes that have come with the high altitude smoke in our atmosphere.

On Monday morning, well before the sun rises there is a treat.

Tomorrow night offers a real treat. The brilliant red planet Mars will appear close to the gibbous moon.

There is plenty happening in the skies in the weeks ahead.
