View Today's Sun and Record Data
What you are going to do:
Using daily pictures collected by the SOHO
spacecraft, you are going to observe and record information
about the currently visible sunspot groups. What do you think
we can learn from watching sunspots?
Don't EVER look directly at the
Sun, with or without a telescope (unless you have the proper filters).
What you need to get started:
Print out and make copies of the
Sunspot Data Recording worksheet.
You will need one for each day of your observations.
You will also need to make a copy of the
latitude/longitude grids.
If you can, copy the grids onto transparency paper.
When you view your images:
If you can, print out a copy of the internet solar image every day.
If you don't have a printer, sketch the sunspot groups you see.
(Try placing the best-sized latitude/longitude
grid directly over the image on your screen to find exactly where
to sketch your spots.)
For each of the major sunspots or sunspot groups, record:
Getting the images:
SOHO collects solar images
in an assortment of wavelengths.
Explore the "full disk" images and
try several wavelengths
to determine which highlight the sunspot groups best.
Sunspots will appear as dark or light dots or blotches on the images.
Start with images for the current day. If these aren't complete, use the previous days'
images. Collect images every day for 10-14 days.
Then, go on to the other activities.
