Thank you for coming!

It was a bit cloudy, but at least it wasn't too cold! We got to see a few things on our target list, including Venus, which showed as a perfect half-moon shape, Jupiter and some fine cloud belts and Mars, with a brilliant white polar cap showing clearly against the orange desert soils of that cold, arid world.

In the photograph below, you can see the Cooke telescope pointing at Venus through the observatory hatch, captured in a one second long exposure.


The full Moon put in a showing, with this view as it rose on the eastern horizon.


Full Moon

There is something really magnificent about the sight of the full Moon sailing up into the sky. For thousands of years people have responded to this dramatic spectacular in the arts, with music, paintings, poetry and even architecture relating to the phenomenon.

Here is a lovely picture taken this week by Verena Kummel, showing clearly the ancient (three billion years old) dark seas overlaid with more recent impact craters.


Can you name the seas? In this picture you can find; The Mare Crisium, Mare Frigoris, Mare Tranquillitatis, Mare Serenitatis, Mare Fecunditatis, Mare Humorum, Mare Vaporum, Mare Imbium, Oceanus Procellarum, Mare Nubium, and many more!

Observatory session, Thursday 8th March, 7.30 - 8.30pm

If the sky is clear, I will open up the observatory on the date shown. Mars has just reached opposition, tucked under Leo's paws and should be a good object to look for, but the full Moon will make it hard to see much more than the brightest few stars otherwise. For the interested, I'll go through the basics of setting up the portable Meade telescope so that you can hire it if you'd like to, and we'll put it through its paces on setting Jupiter/Venus.

Finally, we can try to catch a glimpse of comet Garradd with binoculars, and have a go at taking a picture of it with the Nikon camera.

mail me if you can make it!

Eye witness account of last night's meteorite!

Large Meteorite Seen Over Bootham School
Late on the evening of Saturday 3rd March, a meteorite could be seen making its way across the skies of Northern England. We were surprised and fortunate to catch sight of this phenomenon as we returned to the Fox boarding house after an evening activity in the Sports Hall.
It was like seeing a shooting star, but in slow-motion, in full-colour, and so up-close it felt almost within reach. You could say the head of the meteorite was the size of a football, with a blazing tail of orange and white fire. But perhaps it looked more like a Year-7 student, wearing some kind of jet-boots, like the hero in a sci-fi animation, coolly cruising across the night sky.
In any case, standing on the Fox quad, we saw the meteorite rise over one of the Maths classrooms and travel across Fox House, only to dive behind the Language department and disappear from sight. We almost expected a huge explosion upon impact somewhere on the other side of the river Ouse, but the meteorite continued on its way and is said to have been seen as far south as Devon.   
A sighting like this is very rare, perhaps once-in-lifetime. It was certainly strange and startling enough to leave us (two almost-adults) feeling boyishly exhilarated afterwards.

First session of this year's ISSP

It was very nice to meet all the young people who attended yesterday's meeting of the ISSP, and I was delighted to see so much enthusiasm shown by so many. We covered a lot of ground on the general theme of stars, but in summary yesterday's topics included;
  • the constellations and how they change through the seasons,
  • stellar spectral classes, and what the colours of stars can tell us,
  • how to see sunspots using telescope projection,
  • using transits to measure what time it is,
  • and the stellar magnitude scale.
Here are just a few pictures from the session, and I'm sorry that not everyone is shown but I hope they help to remind you of what you did!







see you next week for the solar system, life in the universe and how we're going to find it!
