The classification system for solar flares uses the letters A, B, C, M or X, according to the peak flux as measured at the Earth by the GOES spacecraft.
These are daily Class X sun flares. The data was created by counting daily flares of this class based on the peak time of the flare.

Shows the daily sunspots back to 2010-01-01.
Based on the data from Sunspot Index and Long-term Solar Observations (SILSO) / World Data Center for the production, preservation and dissemination of the international sunspot number
The estimated international sunspot number (EISN) is a daily value obtained by a simple average over available sunspot counts from...
