Question

Here is a graph that shows not just the number of sunspots over time, but where on the Sun they have appeared. It has been nicknamed the "butterfly diagram" due to the characteristic shapes you see in it Let's take a closer look at it - I have blown up the most recent part, and added some helpful guide lines E> 0.0% > 0.1% > 1.0% 90° N 60° N 500 N 40° N 300 N 200 N 100 N 0o 10° S 20° S 30° S 40° S 0° S 60° S 90° S 1980 1990 2000 2010 Brighter colors represent more or larger sunspots at a given time and latitude. Comparing this graph with the previous solar-cycle graph, we can see some similarities. Let's focus on Cycle 22, which saw solar maximum around 1991 For the next few questions we'll be looking at just the single "butterfly" associated with Cycle 22 - ignore the tail end of Cycle 21's butterfly and the start of Cycle 23's, even if there's slight overlap At the start of Cycle 22, most of the northern-hemisphere sunspots were near what latitude? What about southern- hemisphere sunspots? (2 points) Near the end of the Cycle 22, where were most of for each hemisphere? (2 points) the sunspots Over the course of a single solar cycle, how do the sunspot locations change? (1 point) The lower half of the graph below shows the magnetic-field polarity for the sunspots seen on the Sun: red is north-in-front, and blue is south-in-front, with darker colors indicating a stronger magnetic field. What happens to the magnetic polarity during each new cycle? (1 point) Solar cycles-variation with solar latitude and time Year 22 0012 4002 00 Percent of suns surface and polarity

Answer 1

Cycle 22 starts from 1985 onwards to 1996.Therefore at the start of cycle 22 most of the northern hemisphere sun spots were between 0 to 10 N and that in southern hemisphere were between 10 to 20S.

Towards the end of cycle 22, most of the northern hemisphere sun spots were between 0 to 15 N and that in southern hemisphere were between 0 to 10S.

Over the course of a single sunspot cycle the sunspots location show an increase in both northern hemisphere and southern hemisphere till maximum short of half way period and then steady decrease towards the end of cycle.The increase is over a shorter period than the decrease.

With each new cycle the magnetic polarity undergoes a change.
