SuperMoons, Blue Moon, and a Lunar Eclipse
There are two Full Moons in January 2018, one on January 1 and another on January 31. The first nearly coincides with Perigee, the point during the Moon's orbit where it is closest to Earth. The second is just over a day offset from perigee. There is a perigee every month, so what's the big deal about it coinciding with the Full Moon? Nothing. Does the Moon look bigger? Marginally, but you probably will only notice the difference between a "super" Full Moon and an average Full Moon if you take pictures and compare them. Will the "super" Moon be brighter? Yes, about 7% brighter, but again, that's not enough for the average person to notice. The Moon often looks large when it's rising or setting, but that is different. That's the Moon Illusion, an effect created by us having something to compare the Moon to (trees, buildings, etc). Up higher in the sky, there's nothing to which we can compare the Moon's size, so it appears smaller. But measure it against your pinky finger held at arm's length, and it's the same size no matter it's location.
The second full moon in a calendar month is called a "Blue Moon." It doesn't actually appear blue.
There will be a total eclipse of the Moon on January 31, but we won't be able to enjoy it. The partial eclipse begins at 6:48 a.m. The Moon will be setting. If you want to see it, you'll need an excellent view of the western horizon. By the time the total eclipse has begun, the Moon will be below our horizon.
What an astronomical bummer!

What's up in the Sky?
January sees four planets in the dawn sky: Saturn, Mercury, Jupiter, and Mars. Saturn is just emerging from the glare of the Sun. Look for Saturn low in the southeast early in January, climbing higher each day. Mercury, at greatest elongation January 1, is to the lower left of Antares. Mercury and Saturn pass each other January 13. The swift moving planet Mercury drops lower each morning and is lost in the morning twilight before the month ends.
Jupiter and Mars are about 45 degrees to the upper right of Saturn and Mercury. Jupiter and Mars pass just 0.3 degrees of each other January 6. On January 11, the crescent Moon is next to Jupiter and Mars. By the end of the month, we are left with three morning planets, Saturn, Mars, and Jupiter.
Venus is at superior conjunction January 9 and is not visible.
The Moon is near Mars and Jupiter on January 10 & 11. The waning crescent Moon is near Saturn and Mercury January 14 & 15.
