January 18th, 2018 by Nick Evetts

Here are tonight’s links:
The sun is slip-sliding into a deep solar minimum, apparently:

One small spot, though:

The Event^Horizon 2018/01/05

January 6th, 2018 by Nick Evetts

My thanks to Starstorm for joining in and getting the Maths and Links

https://www.flickr.com/photos/83​96454@N03/39528418921/in/datepost​ed-public/

The formula for the velocity of an object at some distance r from the Sun is:

v = sqrt[GM*(2/r – 1/a)]

Where G is the universal gravitational constant, M is the mass of the Sun, and a is the planet’s semimajor axis.

AFM’s Space Pirate Radio 2018/01/04 Pirates At Perihelion!

January 5th, 2018 by Nick Evetts

Here are the links from tonight’s episode with thanks to Dale 🙂

First off, let’s get this out of the way-nothing happening with the sun.

Of course, since the earth is at perihelion, Marty pointed out that we were enjoying a “Super Sun”

Diane mentioned that we also were getting the Quadrantids:

A Sky Full of Stars: January’s Joys!

December 31st, 2017 by Tavi Greiner

The New Year begins with an astronomical bang, with two perigee Full Moons, four morning planets, two Moon/planets conjunctions, the Quadrantid Meteor Shower, and a lunar eclipse – all in the month of January!

 

PERIGEE FULL MOON – January 1/2: January’s first perigee Full Moon will also be the closest, thus largest-appearing, of 2018. The Moon will reach lunar perigee at 21:54 UTC on the 1st and 100% illumination about five hours later, at 02:24 UTC on the 2nd.

You can use a timezone convertor to determine your local times, but wherever you are, the Full Moon will look especially large and bright during the first two nights of the New Year!

FUN FACT: January’s Full Moon is also know as the Wolf Moon. At perigee, it will be 221,559-miles from Earth.
