- Materials:Computer & access to the internetPrinter hooked up to computer (preferable)Copier machine and transparency paper (optional)
Here are sample images which can be used if you can't pick up current images everyday. In these magnetograms, a sunspot group will usually appear as a pairing of white and dark blotches. Ignore the white square in the middle.
Note: these images were taken during solar minimum, a time when not many sunspots are visible. During solar minimum, there are frequently periods when no spots are visible. At solar maximum, it's not uncommon to see 50 or more sunspot groups.
