Without a doubt, this will be one of the most popular sky sights of 2018. The three things in alignment for the latter part of Jan 31, and early on Feb 1, BR time go as follows:
First, it's a Supermoon, meaning that it will appear larger and as much as 30 per cent brighter than normal. Supermoons are fairly uncommon, and so this moon would be notable in itself – but that's just the beginning. It's the third of three that have come in a row, after those in December and on New Year's Day.
Secondly, the full moon that will rise on 31 January is a blue moon. That doesn't actually mean it will look any different – but rather that it's the second time there's been a full moon in a month. That happens just under every three years.
Third – and probably most notable of all – the same night will see a lunar eclipse. That stunning event will lead to the moon turning a deep, rich red, a sight that has led to it being christened the "blood moon". While the west coast will get a good view, BR will see a partial red glow-weather permitting-in the very early morning hours of February 1.
