EXPERIENCE A RARE LUNAR ECLIPSE WITH SLOOH The Mega Harvest Moon Eclipse is Coming September 27th

It’s time to break out the blankets, grab your friends and family, and pack a festive picnic, because Slooh is inviting everyone to join us for the Mega Harvest Moon Eclipse on September 27th.

The Mega Harvest Moon Eclipse will take place on Sunday, September 27th, at 05:00 PM PDT/08:00 PM EDT/00:00UTC (International Times: http://bit.ly/1KxwTYH). Slooh is going all out for the eclipse, bringing in our feed partners from around the world to provide views of the moon from a number of countries and continents. Our hosts will report live from the U.S. and the United Kingdom, including a live report from the world famous Stonehenge. We’ll even have ongoing weather updates from Scott Sutherland of The Weather Network throughout the show, and in the week leading up to the eclipse, so viewers know exactly where they’ll be able to see the eclipse for themselves.

Slooh is especially excited for this rare event, and is calling on our viewers to share this special occasion with their friends and family by throwing a Lunatic Party! Get your loved ones together, pack a thematic picnic (moon pies, anyone?), and bring Slooh along for the ride, whether on your laptop, cell phone, or other mobile device. We’ll have all the information viewers need to enjoy this brilliant nighttime show, from what causes lunar eclipses, to the different ways people have understood the Moon throughout history, and even how some believe the Moon affects humans in bizarre ways to this day.

 Viewers can use the hashtag #SloohEclipse to ask questions, send pictures, and report their own observations during both shows.

Penumbral Lunar Eclipse Live October 18th

Penumbral Lunar Eclipse Live October 18th

On Friday October 18, the Full Moon will venture into Earth’s outer or penumbral shadow, producing an eclipse.  Slooh, the Community Observatory, will track the Moon with its Canary Islands Half-Meter telescope, showing real-time as well as time-lapse views of the eclipse, accompanied by live narration from Slooh’s Paul Cox, and astronomer Bob Berman.

On the April 25th 2013 there will be a partial eclipse of the Moon, the first of three lunar eclipses in 2013. It will be seen from The UK and Europe, Africa, Asia, and Australia and will look similar to the above image taken by @Jochta of @ReadingAS. The darkening will be at the top of the Moon not the bottom as seen in the image. (more…)

The Lowest Full Moon of the Year

Tonight (actually around 0130 tomorrow morning) the Full Moon will reach its highest point due south, just an hour and a half after the eclipse ends. Despite being at its highest in the sky, you’ll still struggle to see it, as it is very low down. In fact the Full Moon nearest the Summer Solstice is the lowest Full Moon of the Year

First, let’s begin with the definition of “Full Moon”. A Full Moon occurs when the Moon is diametrically opposite the Sun, as seen from the Earth. In this configuration, the entire lit hemisphere of the Moon’s surface is visible from Earth, which is what makes it “Full”. There is an actual instant of the exactly Full Moon, that is the exact instant that the Moon is directly opposite the Sun. Therefore when you see timings listed for the Full Moon they will usually include the exact time (hh:mm) that the Moon is 180° round from the Sun (we call this point opposition). Here’s a list of the times of all Full Moons between June 2011 and June 2012:

Month Date of Full Moon Time of Full Moon (UT)
June 2011 15 June 2014*
July 2011 15 July 0640*
August 2011 13 August 1857*
September 2011 12 September 0927*
October 2011 12 October 0206*
November 2011 10 November 2016
December 2011 10 December 1436
January 2012 09 January 0730
February 2012 07 February 2154
March 2012 08 March 0939
April 2012 06 April 1919*
May 2012 06 May 0335*
June 2012 04 June 1112*

* UK observers should add on one hour for BST As you can see from this table, the instant of the Full Moon can occur at any time of day, even in the daytime when the Moon is below the horizon. So most often when we see a “Full Moon” in the sky it is not exactly full, it is a little bit less than full, being a few hours ahead or behind the instant of the Full Moon. I’ll refer to this with “” marks, to distinguish this from the instant of the Full Moon (they look virtually identical in the sky). The Moon rises and sets, like the Sun does, rising towards the east and setting towards the west, reaching its highest point due south around midnight (although not exactly at midnight, just like the Sun does not usually reach its highest point exactly at noon). And like with the Sun the maximum distance above the horizon of the “Full Moon” varies over the year. The Sun is at its highest due south around noon on the Summer Solstice (20 or 21 June) and at its lowest due south around noon on the Winter Solstice (21 or 22 Dec) (of course the Sun is often lower than this, as it rises and sets, but we’re talking here about the lowest high point at mid-day, i.e. the day of the year in which, when the Sun is at its highest point that day, that height is lowest…) And because Full Moons occur when the Moon is directly opposite the Sun, you can imagine the Moon and Sun as sitting on either sides of a celestial see-saw: on the day when the Sun is highest in the middle of the day (in Summer), the Moon is at its lowest high point at midnight; and on the day when the Sun is at its lowest high point in the middle of the day (in Winter), the Moon is at its highest high point at midnight. This means, in practical terms, that Summer “Full Moons” are always very low on the horizon, while Winter “Full Moons” can be very high overhead. Here’s a table of the altitude of the “Full Moon” when due south. Remember the times in this table don’t match the exact time of the Full Moon, but instead have been chosen as the closest in time to that instant, and so have be labelled “Full Moon” (in quotes).

Month Date of Full Moon Time of Full Moon (UT) Time/Date of “Full Moon” due S Time from/since instant of Full Moon Altitude due S (degrees)**

* UK observers should add on one hour for BST ** The altitude here is based on my observing location in Glasgow, Scotland. You can find out how to work out how high these altitudes are here. As you can see from this table, the highest “Full Moon” due S this year occurs at 0030 on 11 December 2011, when the Moon will be over 56° above the southern horizon (approximately the height of the midsummer mid-day Sun which culminates at 57°34′). Compare this to the “Full Moon” this month, just after the eclipse, in the morning of 16 June, when the Moon barely grazes 10° above the horizon, and you can see just how low the midsummer Full Moon can be. In fact the closeness of summer “Full Moons” to the horizon means that this is an ideal time of year to try and observe the Moon Illusion.  

Total Lunar Eclipse 15 June 2011

Originally posted on Dark Sky Diary by Steve Owens (@darkskyman on twitter)

The first total eclipse of the Moon of 2011 occurs this Wednesday evening, 15 June 2011, and it will be the longest lunar eclipse in over a decade. However the views from the UK (and Europe) will be constrained by the fact that the Moon will be below the horizon for much of the eclipse, and will rise fully eclipsed, or in some cases even coming out of eclipse. It’s still worth having a look though: just try to find somewhere with a very low and clear SE horizon, as this will be the direction in which the Moon will rise, and it will be in eclipse only while it is VERY low (only a few degrees above the horizon).

A lunar eclipse occurs when the Moon, in its orbit around the Earth, passes into the Earth’s shadow, as cast by the Sun. You might imagine that this would happen once every lunar orbit, or once a month. That it does not is due to the fact that the Moon’s orbit around the Earth is tilted by around 5 degrees compared with the Earth’s orbit around the Sun. So in most orbits the Moon passes above or below the Earth’s shadow.
