Solar Projection Tracing 22 May 2011 new

Hi Everyone,

I recently purchased a Sunspotter to use at school and with outreach and have been waiting for some clear weather to try it out. Between many passing clouds it was clear today with good transparency so I took a look at the Lonely Sunspot this afternoon.

AR 1216 is very small (relatively--it's probably two Earth diameters) and showed a distinct umbra surrounded by a penumbra. I rendered it a little bigger than it actually is.

I haven't decided if I like the Sunspotter yet or not but here is the sketch I made using projection to locate the spot and then filling in what little detail I could see (I had to use a magnifying glass).

Very nice sketch and the spotter looks great for school projects and outreach.
Where did you buy the spotter ?

Here in Belgium it is exceptional dry and good weather last weeks. I could observe the sun every day in May! Your sketch gives a nice view of the actual activity of our star: rather calm

Thanks, everybody.

Jef, don't let that placid appearance in white light fool you. Check out this sketch posted in the Solar Observing forum. It was done the same day as my sketch and shows what the Sun looked like in the hydrogen alpha wavelength.

Michael,

They do look like they are good for group viewing.
Nice also for a partial solar eclipse too I would think.

Frank

PS Oh and a fine sketch too

Thanks, Frank. And I agree with you about viewing a partial eclipse. The upcoming transit of Venus (June 2012) should look good, too.

Let say the sun is calm for the poor people

Yes, I know. And solar observing in Halpha can be addictive so you have to be careful what you look through.

On the other hand, I've seen PST's as low as $450...

Great sketch and great idea for outreach, the venus transit should be cool.

Thanks, T5. I'm waiting now for a nice big sunspot to show people. And I'm *really* looking forward to next year's transit of Venus--the 2008 transit was too cool for words.
