Information on Sunspots

[lindsah]

Hi all,

I'm a high schooler from New Zealand and am doing a year long research project on solar weather and am wondering if there is a place where I can find the number of sunspots on the Sun for exact days in the past, as so far I've only been able to find monthly averages for sunspot numbers. This would be a great help to my project and any help is greatly appreciated.

Hello!

This information can be found in our archive. Just browse to the day you want to know the sunspot number of and you will find a lot of information of that specific date, including the sunspot number.

A good topic for a paper!  Note as you collect your data there is a difference between "number of sunspots" and "sunspot number."   How scientists count sunspots and the various ways they are categorized and reported would be a great introduction in your paper.
