2014, The February Sky

Monday, March 3rd, 2014

During February (at least) two interesting phenomena were seen in our skies.

In the evening of 27th February the notable aurora display seen over much of the UK was the stand-out evening sight this month!

More regular, and predictable, was the silent, early morning conjunction of Venus and the Moon. A clearing in the southeastern sky was needed – and such clearings were rare.

Perseid Meteors, August 2013

Saturday, August 10th, 2013
Despite the fuss the press is making the predictions are not for an outstanding display this year but the Perseids are always good even in an average year.
The best night should be Monday (12th) when there could be up to 100 per hour.
There is good information on the Armagh Observatory website:
http://star.arm.ac.uk/press/2013/Perseids2013_pr.html
You can also find details (among the adverts) at Meteor Watch:
http://www.meteorwatch.org/
And slightly more technical at:

This is an American site but gives details for all over the world – so make sure you are reading the northern hemisphere information!

Perseid Meteor Shower, 2012

Saturday, August 11th, 2012

Annually the earth passes through a debris field when the debris particles striking our atmosphere produce a meteor shower.

In August this is the Perseid meteor shower, so-called because it appears to originate in the constellation Perseus.

The best time to look skyward is just before dawn. Continue reading “Perseid Meteor Shower, 2012” »

2012 Transit of Venus

Wednesday, May 16th, 2012

When Venus passes directly between earth and the sun, we see the distant planet as a small dot gliding slowly across the face of the sun.

The next transit of Venus occurs 6 June, 2012.  Observers in or near Tain will see the transit at sunrise : 04:19, transit ends 5:36. This will be the last transit of Venus to occur in your lifetime. Continue reading “2012 Transit of Venus” »

Tuesday, January 3rd, 2012

In the early hours of Thursday, 4th January, 2012, that is sometime near 4am, this meteor shower will peak.

Quadrantid-Meteor-Shower
Look north to find the centre (radiant point).

The meteor shower will last only a short time as the debris we will pass through is narrow.

This year’s shower may be quite productive, showing 40, or 80, or 100, or 200 meteors per hour depending on who is estimating it. One point commentators agree on is that the Quadrantids are unpredictable.

Lunar Eclipse 15 June 2011

Wednesday, June 15th, 2011

On Wednesday night, June 15th, there will be a total lunar eclipse visible from every continent except North America.

The Moon will spend 100 minutes fully engulfed in Earth’s shadow, making this the longest lunar eclipse in nearly 11 years.

The appearance of the eclipse might be affected by exhaust from Chile’s erupting Puyehue-Cordón Caulle volcano, which is also causing spectacular sunsets around the southern hemisphere.

Morning Showtime in the Sky

Tuesday, May 10th, 2011

“It was an awesome morning with an unforgettable view: four planets packed in just a 7º piece of sky,” says Ribas.

“The very compact Venus-Mercury-Jupiter triangle was simply hypnotic. And Mars, below them, was faint but still clearly visible to naked eye. Marvelous planetary gathering, but the best is yet to come.”

Indeed, on May 11th, Venus and Jupiter, the two brightest planets in the Solar System, will converge to form a pair less than 1/2 degree apart. Set your alarm for Wednesday morning and begin the day with an eye-opener–no caffeine required.

Solar Eclipse 4th January 2011

Wednesday, January 5th, 2011

The portents were not good but in places the dawn was clear enough to observe the rising sun partly occluded by the moon’s disk.  Several TDFC members were in place to record this event – here are resulting photos.

A new comet has been found by two Japanese amateurs.  Comet IKEYA-MURAKAMI is visible using a telescope or strong binoculars in the morning just before dawn.  Look east to where Venus is visible below Saturn.  The comet is moving downward and leftward very, very close to Saturn.
