This document discusses sunspot cycle data from 1700-2008 and instructs the reader to graph sunspot numbers from 1965-2008 and answer questions about the average cycle length, whether 2006 was a maximum or minimum year, what 2015 will likely be, and if the reader's birth year was closer to a maximum or minimum.
1. Graphing Sunspot Cycles The data represent the number of sunspots per year from 1700—2008 For example, the year 1965 had 15.1 sunspots Use the data to prepare a graph of sunspot numbers from 1965—2008 Questions : What is the average length between high points in the cycles you graphed? Based upon your graph, was 2006 a maximum or minimum year? What will 2015 likely be? Was your birth year closer to a maximum or a minimum?
