The CV-Helios Network have performed sunspot classifications since 1981 and are always in need for new observers.

The CV, or Classification Values (you can see a sort explanation on thi site at: https://www.spaceweatherlive.com/en/help/the-classification-of-sunspots-after-malde.html) build on the Zürich/McIntosh-system that has been used worldwide since 1972. 

It was built on the old Zürich-table that consisted of 7 letters but was modified by Dr Patrick S. McIntosh.
The CV-observer classify every sunspot region on the solar disk at one day, and each classification has a specific number according to the CV-table that goes from 1 to 60 in value.

In other words, CV-Helios Network do not make use of spotcounts but summarised values of all classified sunspot regions for each day of observing.
CV-Helios Network has about 50 observers worldwide and have collected over 200.000 solar observations since 1981.

A preliminary email-report is issued every month and a comprehensive annual report once a year.

Interesting although I myself am far from being qualified as I have been on this site less than three years.  I have often wondered how it might be reasonably simplified in some manner.
Far be it from me to even suggest we change sunspot polarity designation colours.  This could make an already confusing situation far worse.  😇
