Sunspots
Sunspots are these interesing, temporary, somewhat mysterious dark spots on the
photosphere (“surface”) of the Sun. They are cooler than the surrounding
photosphere and seem to be caused my the Sun’s magnetic fields. They occur in a
cycle which is what we’re going to examine in this lab. 2 points for each question
10 points for the graph for 32 total.
On the last page of this exercise there is a blank graph and a data set on sunspots.
Create a graph as directed below and answer the following questions.
1) Graph the data on the last page of this exerccise by placing points for the
number of sunspots for each year then connect your points with a smooth
curve. Include this graph with your answer sheet
2) How long does a cycle of sunspots last? (from one peak to the next peak)
___________
3) What trend do you notice in the peak number of sunspots? ___________
4) Some people like to claim that global climate change isn’t being driven by
human emissions of Carbon Dioxide, but rather by an increase in the
brightness of the sun which is correlated with sun spots. When the sun gets
brighter there are more sunspots. Looking at the temperature trend since
1990 on the graph on the next page and your graph, does the Earth’s rising
temperature seem to be due to the sun?
SOHO is an orbiting telescopethat studies that sun. Go to the SOHO web
page here https://sohowww.nascom.nasa.gov/sunspots/ and answer the
following questions.
5) Copy and paste the current image of the sun onto your answer sheet.
6) Just looking with your naked eye at the picture, how many sunspots do you
see?
7) Does this number seemto agree, more or less with what you would precict
with your graph? (More or less, rememer your graph is per year, you’re
looking at one day and one side of the Sun)
Finally looking back at your graph
8) What year do you plan on graduating from SPC? According to your graph how
many sunspots on average would you expect that year?
9) How many sunspots per month on average would you predict in 2026?
Let’s look at another prediction. Go here
https://www.swpc.noaa.gov/communities/space-weather-enthusiasts-dashboard
Scroll down to where is says Solar cycle and look at the graph of Sunspot Number
Progression.
10) Do you think the number of sunspots will follow their red line exactly? Why
or why not?
11) Moving your mouse (or pointer) over the graph will show you month and
number of sunspots predicted. How many sunspots are they predicting in
January of 2026. How does their prediction compare to yours?
12) Do an image capture of the graph and paste it into your answer sheet.
