A monthly look at astronomical events in the sky and on Earth

A slightly later bulletin this month. I’m standing in for John Rowland, hopefully doing a decent job!

There are some interesting events taking place this month.  The primary events are Jupiter’s moon transits, 2 meteor showers and the appearance of Nessie on the moon!

The Sky at night on BBC 4 10th October 10 PM covers the forgotten solar system.  Neptune and Uranus have only ever been visited once by Voyager 2 but there are opportunities for further missions.

Well, here we are again at the start of another astronomical season. Autumn can offer quite pleasant observing opportunities as the ground still retains some of the residual heat built up over the summer and the evening temperatures don’t drop too low. In addition, September and October are two of the most atmospherically stable months, with less rain, less cloud and a higher proportion of nights with good seeing. Continue reading →

For most people, the realisation that the days are getting shorter comes as July rolls into August. That last walk with the dog, when suddenly, some stars appear that you didn’t notice the night before, or you realise you’re turning the lights on the inside before your favourite TV program ends instead of after it. All signs that “the season” is just around the corner. And what’s nice about August is that it’s often reasonably warm when it’s dark. What bliss. Continue reading →

Anyone who has read these articles of mine before will know that I never try to make a silk purse out of a sow’s ear. If something isn’t worth getting excited about, I say so. Hyping things only disappoints. So I will be frank: for the rest of the summer and well into the autumn, apart from the ever-reliable Moon, solar system objects are going to be very disappointing. And July is of course the second lightest month in the year, starting as it does only 10 days after the summer solstice, so deep sky object observing is very limited as well. Consequently, this What’s Up will be a bit downbeat. I’m sorry, but that’s how it is. We must be content to look forward to August and beyond when observing opportunities improve dramatically.

Well, we’re now into the lightest month of the year, and apart from the Moon and a few select double stars, there’s not much to see up there I’m afraid. The summer solstice is on June 21st at 0431 and on that day from York, the sun rises at 0434 and sets at 2139. There are no periods of astronomical darkness; the darkest nights on offer are between the 1st and the 7th, when there is some nautical twilight, but other than that there is only civil twilight (Sun 6° below horizon) all night. But let’s make the best of it and see what we can see. Continue reading →

Wow! All of a sudden it’s light in the early evening, with the Sun not setting until 7:40 pm on the 1st of the month. Summer skies and reduced viewing opportunities are ahead, so make the most of what darkness remains before you have to wait until after 10 pm for nautical twilight to end – which is when it ends on the 30th.

And the situation is exacerbated by the fact that all six planets – that are normally observable when skies are not particularly dark – are too distant (e.g. Mars) or impossible to see because they are too near the Sun, or only visible briefly at around 6 a.m. and very close to the horizon.
