It’s always good to know the scale of things…

I love this crazy plan. I guess we’ll know in a month if it has worked. Good luck little buddy.

With an empty can of Guinness, the right type of paper and a pin, you too can take a two month photo of the Sun.

RiAus (the Royal Institute in Australia) were even kind enough to provide me (and many others) with the photographic paper for free. Thanks!

OK. Wow. I was pretty proud of my sunspot efforts until I saw this. Always good to have something to aim for, I guess.

City of (Sunspot) Lights

Sunspot AR1476 (photographed above over the Eiffel Tower) has been monitored all week, as the Jupiter-sized coronal “active region” has been pointed squarely at Earth, ready to release a wave of magnetic energy in the form of a solar flare or coronal mass ejection. Last night, a CME was detected, racing toward Earth at over 1,000 km/s.

This awesome animation from the Goddard Space Weather Lab demonstrates the forecasted wave and glancing blow we await on Earth (we aren’t in any danger, but satellites may be disrupted):

Above, the sunspot is photographed Thursday evening over the Eiffel Tower by VegaStar Carpentier.

Trial run for the Transit of Venus in June. Thought I’d better perfect the art of solar visualisation before the big day in front of my students. Turns out it wasn’t that hard – even got some sun spots in focus (the focus on the paper is better than my camera could manage). The SOHO image (orange) is added for reference.
