Merci MariusP!...eu am uitat sa postez ca am primit raspuns de la Solar Influences Data Analysis Center, citez: "Therefore, a single isolated spot is a separate sunspot group (as can always be seen in solar magnetograms, where a corresponding small magnetic dipole appears at that location). So, in this case, you must add 11 to the Wolf number: 1 for the spot and 1x10 for the group." Deci, o pata izolata e considerata grup si pata individuala in formula Wolf:D
Referitor la fragmente de penumbra, am gasit urmatoarea in cartea The Sun and How to Observe It: "Penumbrae and pieces of penumbra are not counted as sunspots"
