No. At the most, you can only ever have 29 cloudy nights in February. Some other months are much worse. ;-)

Another astronomy podcast

I've just been listening to the Birmingham ThinkTank Planetarium's new podcast which sounds pretty professional.
It comes hot on the heels of Jodrell Bank's wonderfully named Jodcast. You cam listen to them on your MP3 player or computer.

To put it very simply, magnitudes are a scale by which we measure brightness. The higher the number the fainter the object. Each successive number is very approximately 2.5 times fainter than the previous whole number. Therefore a magnitude 2 star is approximately 2.5 times fainter than a magnitude ...

I have heard our very own former president Ian Morison advise a similar technique with the hollow legs you get with many aluminium telescope tripods nowadays. You just need to make sure the sand doesn't just all spill out. He didn't say if he had applied the technique at Jodrell Bank where he works....

It sounds like your contributions were vital. It also shows that planning applications are by no means foregone conclusions and that articulate and well-organised protest campaigns can be very effective. Congratulations.

There is a rather nice animated gif image of this supernova on the Faulkes Telescope website.

Yes, I can just make out Sagittarius to the right.

I'm just wondering whether Unclevodka's problem might have been due to some dew on the optics - that would certainly blur the bright moonlight.

I remember observing Algol many many moons ago as one of my projects for astronomy O-level. I observed several eclipses and superimposed all the observations to form a single light curve about the zero time of predicted minimum. Trouble was the dip did not fit the expected time of minimum. The SPA (...

Personally, I use Photoshop Elements - very reasonably priced compared to the pro version but it has a very useful "save for web" function where you can immediately see and choose the trade-off between quality and file-size.

I dare say there are shareware equivalents that work as well.

I agree with Jeff. Great images but they were slow loading even on my broadband. Let's stick to the (very sensible) guidelines, shall we, everyone?

Google moves Greenwich Meridian

Here's a fun one. The Register website notes that Google Earth shows the Prime Meridian running about 100 metres to the East of its correct position. A page at the Royal Observatory's website suggests this is not Google's fault but a general problem with the GPS system because the Earth is not a per...

Very definitely! I've been a member of the SPA for nearly 40 years and I've been helping run it in some capacity or other since 1970! So just try to keep me away!
Thank you for the kind words.
