You might be hearing a bit in the news about there being a “Super Moon” tonight.
What exactly is a “Super Moon”? Is it really that different to a normal full Moon? Are they rare?
As many would know, the Moon orbits around the Earth in an elliptical orbit. It’s not totally circular. This means that sometimes the Moon comes slightly closer to the Earth (perigee) and at other parts of its orbit around the Earth (apogee) it will be slightly further away from us. It does this every orbit around the Earth or roughly every 28 days.
2019’s farthest apogee comes on February 5, 2019 at 406,555 km. The closest perigee is today, February 19 at 356,761 km. The Moon is approx. 50,000km closer during this time.
Some guru came with the term “Super Moon” to describe a Full Moon that happens to coincide with a close lunar perigee approach to Earth. It appears bigger because it is actually physically closer to the Earth and generally occurs a few times a year.
Does that 50,000km make much of a difference? As you can see from the pic, the closer Super Moon is a tad larger than a normal Moon. It’s not a massive change – but like all full Moons, will be a spectacle in in the night sky and one well worth heading out to see.
If you take any images of it, please feel free to share then in the comments!
Adam Lundie posted this image in the Sky-Watcher Australia Facebook group of the The Skull & Crossbones Nebula (NGC2467) taken with his Sky-Watcher Black Diamond/EVOSTAR 120ED telescope on a Sky-Watcher EQ8 mount using a QSI 683-WS8 Camera chilled to about -15°C. This false colour image is the result of some 27 hours of exposure!
NGC2467 is an active star-forming region approximately 20,000 light years away in the Perseus arm of the Milky Way.
This image is a false colour representation of hydrogen-alpha, sulfur-II and oxygen-III emission-line clouds, mapped to red, green, and blue respectively.
Thanks for posting this Adam!

Great pics of the Moon by Nicci Barrett using her Sky-Watcher 200mm (8") Dobsonian telescope, standard 25mm eyepiece and iPhone 7 attached to the telescope using a smartphone adaptor.
Another example of how getting started in astrophotography doesn't require super expensive gear to start taking photos you'll amaze yourself with.

The International Space Station (ISS) moving in front of the Moon as captured by Szabolcs Nagy using a Sky-Watcher 250mm (10") collapsible Dobsonian.
Very cool short video!

An opportunity popped up in calsky, a possible chance for a lunar transit. It was predicted roughly 30mins before sunset, so I did not have too high expectations about the final result. Moon was at 41° above horizon at the time of transit.
Well I had doubts to even have clear sky, clouds were heading toward east leaving nice clear skies behind - but the question was if it clears up in time or not.
It did at the right time, so I could capture the transit which I only saw from the corner of my eyes wgilst :) When I watched the recorded video I was jolly happy 😄

------------------
A Hold előtt elhalad a Nemzetközi Űrállomás, nem kellett messzire autózzak ahhoz, hogy a Hold pereme mentén haladjon. Meglepődtem az eredményen, sokkal sápatabb Holdat és Űrállomást vártam, mivel a Nap még fent volt jó fél órát az átvonulás után.
Mivel még világos volt, a szokásos ISS előrejelzések nem mutatták. De pontosan ezért érdemes időről időre ellátogatni a calsky weboldalra, épp az ilyen csemegékért :)
Az áthaladás után rögtön készítettem videókat egy teljes alakos mozaikhoz fotóhoz is, úgy csak jobban mutat majd az ISS ;)
Áthaladás ideje: 16:43
