Solar Disk Drawing Blank

This should printout to a 15cm diameter circle on most printers. Try to use thin paper if your printer will allow it but be careful as thin paper can become jammed in some printers. Use this template to record all the sunspots you see on the solar disk. When completed, scan and email them to the Director or post it at the end of the month (Microsoft Word).

SPA Active Region and Relative Sunspot Monthly Activity Form

Use this one-page form to record your sunspot activity. Guide to completion can be found on the second page of the template (Microsoft Excel).
