Hi,
Just a little extension that checks for a RSS feed from the Spot The Station website and gives you two variables that you can include in your templates issnext and issall.
To get the url visit
http://spotthestation.nasa.gov/ and pick your country, state and city then grab the RSS link. Once the plugin is installed you will able to update the url in the Station section of your weewx.conf (maybe this should go in the stdreport configuration for the extension?)
For how you can use these variables see the included skin, which looks like:

Its working well on my desktop simulator 34 but if anyone fancied giving the install a little test drive and feeding back I would be grateful. It probably needs updating to only check every 60 mins but it should be good enough for a beta blast.
Thanks
Chris
