The Perigee Moon ("Super Moon") of Tuesday January 2, What Can You See?
A full Moon at perigee has been called a "Super Moon", this is not an astronomical term (the astronomical term is perigee syzygy, but that doesn't trip off the tongue so nicely), but an astrological one first coined in 1979 (see here).
Still, it is a good excuse to get people out and looking at the Moon.
While perigee (closest approach) of the Moon is actually during daylight hours on the 2nd, the rising Moon is still closer than the December 4 perigee Moon at its closest approach (356946 km at astronomical twilight vs 357493 km on 4 December at closest approach (which was before the Moon rose here in Australia).
Even so it will be hard to distinguish from most normal full Moons. However, if you have a good memory you should be able to distinguish it from the apogee mini-Full Moon of June 8 2017, or keep it is mind for the upcoming apogee mini-Full Moon 27 July 2018.
