15	Center Longitude_hmi	deg	int	Sunspot group longitude in heliographic degrees (mea- sured in degrees east or west). It provides the east-west position of the region on the Sun’s surface
16	Area	uSun	int	Total estimated area of the sunspot group in millionths of the solar hemisphere. This field quantifies the size or area covered by the entire sunspot group
17	Z	char	string	McIntosh classification of the sunspot group. The McIntosh classification is a system used to categorize sunspot groups based on their visual characteristics, including the arrangement and com- plexity of sunspots and magnetic fields. It provides informa
18	LL	deg	int	Longitudinal extent of the sunspot group in he- liographic degrees. This field indicates the east-west extent of the sunspot group on the solar surface
19	NN	index	int	Total number of individual sunspots visible in the sunspot group. This field specifies how many individual sunspots are part of the sunspot group
20	Mag Type	char	string	Modified Mount Wil- son classification of the sunspot group. The Mount Wilson classification is a system used to categorize sunspot groups based on their magnetic prop- erties. The ”Modified” classification may indicate a variation or adapta- tion of the
