Full Moon
This event is visible to the naked eye from Austin.
TUE, 26 DEC 2023 AT 18:33 CST (00:33 UTC)
The Moon will reach full phase. At this time of the month, it is visible for much of
the night, rising at around dusk and setting at around dawn.
The Cold Moon
The sequence of full moons that fall through the year are sometimes assigned names such
as the "Cold Moon", according to the months and seasons in which they fall. This
practice has been popularised in recent decades by the Farmers' Almanac in the United
States. The names used by that almanac claim to have ancient origins from Native
American tribes. This claim has been examined in detail by Patricia Haddock's book
Mysteries of the Moon (1992) and is partially true, but the selection of names is
largely arbitrary.
Throughout history a great variety of different names have been given to the sequence
of lunar cycles through the year, and modern lists of such names, such as those
popularised by the Farmers' Almanac, tend to inevitably be a medley of names taken from
many different cultures.
According to the Venerable Bede's De temporum ratione (The Reckoning of Time; 725 AD) –
an authoritative account of the calendar used in Saxon England – the lunar month
containing the first full moon after the December solstice (within winter) was called
the "month after Yule (Æfterra Gēola)".

oops...hit post accidentally here's more as article continues:
The biography of Charlemagne (circa 817–833 AD), written a few years after his death, gives a name of the "winter month (Wintar-mánód)" for the same lunar month.
However, in the scheme followed by the Farmers' Almanac, which has become rather widely quoted, any full moon in the month of December is called the "Cold" Moon.
The exact moment of full moon
The exact moment of full moon is defined as the time when the Moon's ecliptic longitude is exactly 180° away from the Sun's ecliptic longitude, as observed from the center of the Earth. However, the Moon does not
appear in any way special at this instant in time, and a full moon can be observed at any time of night.
At the moment it reaches full phase, the Moon will lie at a declination of 28°08'N in the constellation Auriga . It will lie at a distance of 391,000 km from the Earth. The chart below shows the size of this month's
full moon in comparison to the largest (perigee) and smallest (apogee) possible apparent size of a full moon, drawn to scale. (Image at link provided)

The celestial coordinates of the Moon at the time it reaches full phase will be:
Object Right Ascension Declination Constellation Angular Size
The Moon 06h20m50s 28°08'N Auriga 30'29"
The coordinates above are given in J2000.0.
