I'm not sure how exciting this is, but I'll probably take some time to watch the web cast of the solstice from Newgrange this morning (starts at 8:30). The forecast is good for both today and tomorrow, when you can catch the 'light show' again.
UPDATE 8:20: Now it looks like the Heritage Ireland web site is down. Too much demand for their site even though the good stuff doesn't start for another 10 minutes?
UPDATE 8:37: Okay, I have the stream running now. So far, not bad.
UPDATE 9:55: Well I have to say it was better than I expected. The weather was perfect and the sun rise spectacular (allowing for web cast quality). The commentary was a little livelier than I anticipated and not excessively gushy.
Some of the discussion on the change in the Earth's tilt over the past 5,000 years was good. And the periods of silence were welcome too. Overall, it was more distracting than was probably good for my productivity.
Near the end of the commentary they said that the video would be archived and available on the web site for the next year. You can also catch it again tomorrow, live, from 8:30GMT.
