2020 General Lunar Viewing

Post by Christopher K. »

Although Full Moon may last only an instant, to the human eye the Moon will look Full for a number of hours--perhaps even multiple nights for those who don't moongaze regularly. Conversely, New Moon is a time to take advantage of our natural satellite being "out of the way" and not reflecting sunlight; this is the night for deep sky observing.

New Moon is at 4:28am CDT tomorrow morning. This upcoming nighttime period, and tomorrow's, can be used for deep sky observations. The best viewing time, according to NOAA, will be 8:45pm CDT to 11:30pm CDT.

Here is the NOAA forecast for 10pm...
precipitation potential, 5%
sky cover, 35%
relative humidity, 81%
temperature, 22˚C
surface wind, S 13 km/h

Danko's Clear Dark Sky states that during HRPO's viewing time the transparency rating will be "below average" (2 out of 5) and the seeing rating will be "poor" (2 out of 5). Between 3am and 4am, the seeing will be better but the humidity will have spiked to 97%.

According to Astronomy magazine, this is the 180th anniversary of the first imaging of the Full Moon. John Draper got a daguerrotype in New York.

The Moon will be in a moderate conjunction with beautiful Aldebaran tonight. Take a look from 8pm to 8:30pm. You'll find the Moon in Aldebaran's home constellation of Taurus the Bull, with the K-class star to the Moon's lower left. There are bonuses! The Pleiades Star Cluster is to the Moon's lower right, with the planet Venus directly below. The majestic constellation Orion is on his side to the Moon's left.

Here is the NOAA forecast for 8pm CDT...
precipitation potential, 1%
sky cover, 38%
relative humidity, 47%
temperature, 23˚C
surface wind, NE 10 km/h

Danko's Clear Dark Sky states that during HRPO's viewing time the transparency rating will be "too cloudy to forecast" (0 out of 5) and the seeing rating will be "poor" (2 out of 5). This is a forecast with quite disparate data; hopefully a good view of the Moon and Aldebaran will be forthcoming.
