Counting Sunspotsgroups

On this page you can compare your observations with the observation I made on that day.
PLEASE take note that the cassification mentioned on the pictures is made by me , using my several years of experience and I am not saying that this is the correct way.
The purpose of this page is to start discussions about counting groups.Feel free to send me an e-mail!
Some information about the pictures:
North is on TOP ! East is one the RIGHT side !
First letter is the letter of the Waldmeier Classification, the numbers after the letter are the number of spots I have counted that day. D14 means: group of type D with 14 spots.
Not visible on pic., means that the resolution is not good enough to show the spot or group. These spots where clarely visible at the eyepiece when the observation was made .
From january 2001 I use the MDI Continuum pictures of the SOHO.
