The Sun (Solar Observing)

If you have never viewed the Sun before PLEASE ask one of our members to show you how to do this safely and read the page on Solar Safety before attempting any kind of viewing of the Sun!

Sunspot Numbers
When observing the Sun consider taking a count of active areas and calculating the relative sunspot number (R) and reporting these to the BAA Solar Section
The Sun has an obliquity to the ecliptic of 7.25° if you record your solar observations as drawings then you should use the appropriate Stonyhurst disc as a template, this will allow you to identify the latitude of the sunspot at any time of year.

Active Areas or Sunspot groups (g)

This is a count of all the active areas on the disk, if there is a sunspot, however small, this is an active area (group) if sunspots are separated by at least 10° then they are separate active areas, a large spread out area is still considered a single AA unless there are clear centres of activity within the larger area, then they are counted separately.
Relative Sunspot Number (R)
To find the Relative Sunspot Number count all the individual sun spots call this number, f, then the relative sun spot number,
R = (10 x g) + f

The BAA split these into Northern and Sothern Hemispheres of the Sun so it is worth calculating and counting active areas and sunspots for each half of the solar disk, more information on how to do this can be found on the BAA Solar Section Website
sun_mc01t.jpg
Example: 3 active areas, 35 spots, R=(10x3) +35 = 65 (no other spots on disc)

Reporting
Regardless how infrequent your observing the BAA Solar Section are happy to receive your observations, these can be in the form of images, drawings and monthly reports all the report forms can be downloaded in this BAAReportForms.xlsx single Excel file.
