evening sky finds the waning Moon rising at 7:50 pm in the east located in the constellation
Leo the "Lion" and is at phase 91.58% lit. The Moon is
only Angular separation: 01°10'08" degree from the magnitude 1.36
bright star Regulus in Leo. The Moon is visible all night casting
its pale winter light. January’s Full Moon is popularly known as the Wolf Moon, a name derived from Native American lore, or the Moon After Yule.

is very bright at -4.4 magnitude seen after sunset in the west
southwestern evening sky just 07°55'59" below Mars. Venus is located in the constellation
Aquarius "The Water Carrier".
Venus sets at 9:01pm. Venus had reached greatest elongation east of the Sun on the morning of the 12th.
Venus is at phase 49.77% and appears as a
tiny first quarter Moon. The next few weeks Venus phase will become more crescent-shaped as
the apparent diameter grows ever larger. See Venus as seen through
a telescope On January 14th as shown below.
is visible low in the west southwest after sunset located in the constellation
Aquarius "The Water Carrier". On the evening of the 14th
Mars is 07°55'59" above Venus. Mars sets at 9:41 p.m. Mars is
disappointing as seen through a telescope now as the planets disk
size has become smaller due to the increasing distance from Earth.
See below location of Mars and Venus at 8:00 pm January 14th.
is in the south southwest in the constellation Aquarius the
"Water Carrier". Neptune is 02°09'36" below Venus. Neptune sets
at 8:50 pm. You need a telescope to see Neptune and best looked
for early in the evening around 6:00 pm.. See below of location of

Pisces the "Fishes". Uranus can be found with
binoculars and a dark clear sky. Uranus sets at 12:17 am. See
Uranus location at 9:00 pm on January 14th.
Hubble Space Telescope
Hubble Space Telescope will make a low pass in the south west
evening sky beginning at 7:17 pm at 3.1 magnitude. See location
and times of positions of HST in image below. HST enters Earths
shadow at 7:20:04 pm when sunlight no longer illuminates the satellite
and it is no longer visible.
The Quadrantid are active from January 1st to January 10th and
peaks on night of January 3 through the morning of the 4th and
best time to observe is around midnight till dawn.
This shower probably will produce around 25 meteors per hour but
possible to produce 120 +per hour. There is not a Moon to hinder
observations this night. These meteors often produce bright fireballs.
It is thought that 2003 EH1 may be the remnant of a larger
parent comet called C1490 Y1 that results in this meteor shower
when Earth passes through the old debris stream. Click on image below for more information.
"The Lion" is rising above the eastern horizon. The

Picture of the Day
Our sun is almost one million miles in diameter and a million earths would fit in it.
It takes light eight minutes to reach us from the sun.
The last star shown in video is VY Canis Majoris which takes light about 5000 years to reach us
that is light traveling at 186,000 miles per second x 60 seconds
in a minute x 60 minutes in an hour x 365 days in a year x 5000 years.
VY Canis Majoris is (almost 2 billion ) 1.7 billion miles in diameter.
