Forms
Solar Disk Drawing Blank
This should print out to a 15cm diameter circle disc on a printer. 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 me or post it if you prefer. In MS Word format.
SPA Active Region and Relative Sunspot Monthly Activity Form
Use this Excel form to record your sunspot activity every month. Type in the numbers in the white boxes and it will work out your averages in the yellow boxes. Update each day you observe and send the form to us at the end of each month. There is a guide to completion on page 2 of the form.
