Chis has also looked at the sun with his telescope and he mentions:
"I have looked on Wednesday afternoon; I have seen 7 sunspots at about 30 degrees South and 7 sunspots at 30 degrees Northern longitude. Lattitude for both groups is about the same. Certainly worth a look. It is several years ago that I have seen such a large group. Apparently the minimum in solar activity in the 11 year cycle is passed".

A short update. This afternoon (February 10) I have once again pointed my ETX-125 with solar filter to the sun to check if something has changed since a few days ago. And that was clearly the case. Now there are two groups of sunspots. Both groups were already visible in the picture of last Monday, but the smallest group consisted at that time of 1 small and 1 larger sunspot surrounded by brighter (hotter) spots.

On Saturday February 6 I pointed my ETX-125 for a test with a solar filter to the sun. To my surprise I detected a large group of sunspots. The next day I got an alert from Nasa about this group.
Today, February 8, I once again pointed my telescope with solar filter to the sun to find out that the group had grown considerably. The group consist now of a long spanning group of large and small spots. On Saturday this group was more compact. Apparently there is a lot going on in the sun.
