Major Lunar Eclipse on October 8th

Wednesday, October 1st, 2014

Following hot in the heels of the last Lunar Eclipse which occurred on April 15th, once again the Western Hemisphere will be treated to a second Full Lunar eclipse.

In Vancouver it was a slight disappointment as right at the high point of the event in came the clouds and ironically enough, just as the show was winding down, well, so the clouds began to race away again! Hopefully we will get a better chance of a more complete show on October 8th and it seems to be happening around the same time as the last, so that means a very late night or very early morning for some.

There has been plenty of excitement surrounding these particular Lunar eclipses as they are a series of ‘Tetrad’ eclipses, this means that there will be 4 Eclipses happening over 2014 and 2015 which is quite a rare happening. Here in Vancouver we will be lucky enough to witness a full Lunar eclipse.

There are a few other type of eclipses that can be watched around the earth and they are catogorised into the following types.

Total lunar eclipse
This is the daddy of them all, it essentially means that we are right in the path of totality where the Earth is exactly in between the Sun and the Moon – if it is a clear evening you can watch the Sun set and if you look in the opposite direction, pretty much at the same time as our gorgeous Sun sets the Full Moon will also start to rise. It is quite the sight and stunning moment where the transition from day to night occurs with the two brightest objects in our sky.

Partial lunar eclipse
If you are able to witness the full Eclipse one thing you will notice is that as the Earth begins to pass in front of the Sun a bite is taken out of the Moon as the shadow of the Earth starts to remove the light of day from the disk of the Moon, unlike a Full eclipse where the Moon will completely darken and redden in colour, with a partial eclipse only a portion of the Moon is covered in the Earths shadow. Some are not very spectacular, while others may dominate much of the Moon, either way it is a noticeable difference for us down here on earth.

Penumbral lunar eclipse
This is the least spectacular of the bunch as all we are witnessing here is the Earth slightly passing in front of the Sun, for any astro boffins this is called the Prenumbral stage – when watching the full Lunar eclipse this marks the very beginnings and ending of the stages of an eclipse – to many this is not very noticeable eclipse depending on how much of the Earth is blocking the Sun.

The next eclipses of the Moon after October 8th will occur on April 4, 2015: Total Lunar Eclipse: Visible from the Pacific Ocean and bordering regions in the Americas, Asia and Australia, and on Sept. 28, 2015: Total Lunar Eclipse: Visible from east Pacific Ocean, Americas, Europe, Africa, western Asia.

Celestial News and happenings in April 2014

Full Lunar Eclipse
On April 15th the majority of North America will be treated to a spectacular full Lunar eclipse, this occurs when the Earth passes between the Moon and the Sun.

The viewing time for this celestial treat will occur at a reasonable hour for once – so for us Vancouverites here in Sunny Canada will be able to watch the show from from the start time at 9.55pm when the Earth’s shadow begins to darken the moon. Totality occurs 12.08am – this is by far the most breathtaking moment to witness – the Moon will darken a-lot but will glow with a deep dark red colour as the Earth still reflects the Suns Rays – seeing the Earth eclipse the Sun from the Moons vantage point you would be treated to a darkened globe of the earth with a red fiery Halo circling the earth – which really is an infinite image of the Sun rise and Sun set- quite an awesome trick of the light.

Totality ends at 12.46am as the deep red glow moves over so you just have a more darkened disc of the moon as the larger earth shadow still prevents the full light from the sun penetrating the Lunar landscape. The whole spectacle will all be over by 3.36am. This event is quite a long one as we are luckily enough to be in the direct path of the full eclipse.

This event is also a little rare as it is the first of Four Full Eclipses that will happen between now and September 2015. This series is known as a Tetrad of eclipses. The next full eclipse in our part of the world will happen again on October 8th 2014.

Other Celestial events this month to watch for.
Planet Mars at opposition.
Carrying on with the Red colour – the month of April also marks the best time to witness the Red planet Mars which sits at opposition where our planet Earth sits directly between the Red Planet and the Sun – this gives us the best viewing of Mars in a couple of years, it will rise at Sunset and set when the Sun rises and should be easily visible in the night sky the whole night!

April 22, 23 – Lyrids Meteor Shower.

These may not be the strongest of Meteor showers, but with patience you may get to see some pretty bright streaks across the sky, especially if you are in a location that is away from the bright street lights.
These showers happen every April as the Earth swings around the Sun on its orbit and during this part of the year it passes through the dust trail once left by the long-period Comet C/1861 G1 Thatcher.

The actual event lasts around a week – but the dates of April 22 and 23rd will be the peak times to watch the show.
