I went to the spaceweather.com site updated 19 Feb 2025.

Today the Sunspot number is 187 which is in agreement with the graph that I posted yesterday.

The Spotless Days table shows there have been no days with zero sunspots since 2022 when there was 1 spotless day.

Sunspot number: 187
What is the sunspot number?

Solar Cycle 25 maximum



The Sun has been very active during the last few months. Since April this year, many large and complex sunspot groups have adorned the solar disk driving the daily sunspot number regularly to well above 250 (see the SIDC/USET image for 7 August underneath). sidc.be
