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.
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:
Russell managed to see the northern lights on Monday night as a large parcel of cosmic rays ejected from the sun came sweeping through our atmosphere. Continue reading “Aurora, October 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” »
In the early hours of Thursday, 4th January, 2012, that is sometime near 4am, this meteor shower will peak.
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.
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.

“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.
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-MURAKAMIis 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. Continue reading “New Comet — Ikeya-Murakami” »
