What’s Up

June Night Sky

June is the gateway to the summer months whereupon Astronomy Societies appear to commence hibernation for three months awaiting the retreat of the Sun. But there is no reason for observing to stop; yes we've temporary lost 'darkness' and at best see just astronomical twilight but there is much more out there to enjoy. Firstly, you may be starting late in the evening/approaching midnight but it's t-shirt weather even in the early hours. Secondly, the firmament above doesn't stop to go on holiday. The spectacular solar eclipse will still occur in the US on 21st August. Cassini will continue...

Observing evening at Wellow, Thu 25th May

REPORT: A good night in Wellow last night and this morning even though the sky remained in astronomical twilight for the duration. A 3 hour session from just after 10:00pm meant that many would be tired at work in the morning. 5 members were able to attend and enjoy the night's celestial delights with a good proportion of observing through binoculars although 5" abd 8" telescopes were also on site. A special thank you to Stephen M for his guided tours of his favourite objects. The evening kicked off with Jupiter and with the transparent skies, the equatorial belts were very impressive....

May Night Sky

Spring is moving steadily onto Summer and the frosts are diminishing. May is a month where we lose the night time and are simply bathed in astronomical twilight as the Sun is approaching its highest northerly declination and never retreats far below the horizon. This same physics leads to the land of the midnight Sun as your latitude increases. To some the end of May is the death knell for serious observing until late Summer but there is the alternative view; the medium to bright objects are still readily visible, the nights are warmer and you can spend time either just starring at the sky with...

Observing evening at Wellow, Sat 22nd April

REPORT A hugely successful Saturday evening under the stars with Bath Astronomers at Wellow on Saturday night. The sky clouded over soon after meeting up at 21:30 but even the poor weather forecast by metcheck.com suggested the high cloud would clear. To fill the time, we looked at the two new scopes brought to the evening, a 5" Newtonian on an equatorial mount and an 8" Dobsonian. Problems with focusing, mount alignment and navigating the sky were all openly chatted about. Hopefully Marjorie, Rachel, Steve and Francis who attended with Simon found it helpful. After almost an hour, the skies...

Observing at Wellow on Sat 1st April

Attendees - Jonathan, Charles, and about 8 visitors at Wellow, from 20:00 Dusk was still falling at 20:00, with a 3-day old moon, transparent skies, but also 50% cloud cover. Great views of the moon, and bright double stars (Castor, Mizar) as dusk descended, plus plenty of chat about telescope options. But the cloud cover increased to about 95%. Most departed by 21.30. Charles stayed on, and the skies got back to about 50% clear. This was good enough for a look at the bright Ursa Major galaxies (M51, M81, M82, even M101), and in Leo (M65, M66; M95, M96), M3, and a quick look at Jupiter....

April Night Sky

For me, April is galaxy month. The Virgo and Coma galaxy clusters offer much the best galaxy field for amateur telescopes in the entire night sky, with scores of galaxies available to observers at a reasonably dark site with an 8" telescope; hundreds if you have a 12". April is on balance the best month to see them because they reach their highest elevation due south before midnight.(You can still see them in later months, but then you have less night time available as the evenings stay light so late.) The map below gives a sense of both galaxy clusters, as well as several groups of interesting...

March Night Sky

March provides the best opportunity this year to see Mercury in the evening sky for us northerners. Mercury is never very far away from the sun in the sky, so for evening appearances you have to catch it after the sun has set, but before Mercury does. The geometry of our position on the earth's surface, and how that relates to the ecliptic (the plane in which  that the planets of the solar system orbit) means that the best opportunity for this is around March. This is when the sun is "moving" northwards in our sky at the maximum rate, and a planet setting after the sun is therefore approximately...
