2018 Lunar Phases and Distances

Post by Christopher K. » December 30th, 2017, 7:17 pm

The first Full Moon of the year will be exactly at 8:24pm CST--and it's a Supermoon! It will have a 33.5' apparent diameter, easily being the largest Moon of 2018. At that time the Moon will be thirty-eight degrees up in the east, 4˚42' northeast of the A-class, magnitude 1.9 Alhena. It'll be 100% illuminated throughout the entire nighttime period. (Remember, the temperature is forecast to be below freezing by 5:30pm Monday evening.)

The Supermoon status is due to perigee happening earlier, at 3:49pm CST.

On the 2nd, starting at about 9pm CST one can see in the east a twenty-five degree-wide arc formed of Castor, Pollux, the Moon and Procyon. Starting at about 10pm CST on the 3rd, one can see an almost-equilateral triangle formed by Pollux, Procyon and the Moon (each side at least twenty-one degrees long). Take a look...

New Moon is tonight at 8:17pm CDT.

The best viewing time from twilight to twilight is now until 8pm. Danko forecasts "average" transparency and "seeing" from 5pm to 8pm, and this is the NOAA forecast for that same time period...
precipitation potential, 0%
sky cover, 4%
relative humidity, 55%
temperature, 11˚C
surface wind, SE 4 km/h

New Moon was today at 3:05pm CST. According to Sky & Telescope and Fred Espenak the Moon is currently partially-eclipsing the Sun as seen from portions of South America and Antarctica.

Full Moon was at 6:51pm CST this evening (I'm posting this during the 11pm hour, but the bulletin board mechanism adds an hour to the post time). The humidity is close to calling off a look, but it looks nice.

It was New Moon at 2:43pm CDT today. For those interested in attempting the view a "youngest Moon" tomorrow, it will be about fifteen degrees removed from the Sun at the end of the day. The Sun will be six degrees up at 7:33pm; sadly, the forecast indicates the weather may not cooperate...
precipitation potential, 21%
sky cover, 77%
relative humidity, 72%
temperature, 29˚C
temperature, 32˚C
surface wind, SE 8 km/h

Full Moon is tonight at 11:53pm CDT. Below is the NOAA forecast for that time...
precipitation potential, 10%
sky cover, 22%
relative humidity, 87%
temperature, 27˚C
heat index, 30˚C
surface wind, S 8 km/h


Danko's Clear Dark Sky states that during HRPO's viewing time the transparency rating will be "average" (3 out of 5) and the seeing rating will be "good" (4 out of 5).

Saturn will be extremely close to the Moon--less than a-degree-and-a-half to its lower right.

Full Moon is tonight at 9:52pm CDT. Below is the NOAA forecast for that time...
precipitation potential, 23%
sky cover, 67%
relative humidity, 87%
temperature, 25˚C
surface wind, SE 5 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 "good" (4 out of 5).

This Full Moon is known as the Harvest Moon--the Full Moon nearest the autumnal equinox.
