Sunspot observations April 2011

In April, I made sunspot observations allways when possible. In total, I managed to make observations in 10/30 days. I made my observations in Sodankylä, Northern Finland with my new 102/1000mm refractor. I wasn’t able to see any naked eye sunspots in April. The mean sunspot number in April 2011 according to my observations is 49,9. Here are my observatios as a table (Time: GMT +2):
