Solar Cycle



As with everything in nature the sun has a solar cycle also known as the solar magnetic activity cycle. This 11 year cycle was determined by research agencies by monitoring sunspot activity. In turn this is related to a 22 year cycle for the reversal of the Sun’s magnetic field. The magnetic fields are very much a part of the Sun’s production of the energy we require for life.

 

Now what has this to do with a suntan you may ask? Well, all these pieces are part of determining our weather and UV emission levels. The strength of the UV types A and B plus the time spent in the sun dictates how your skin reacts. This in turn determines whether you achieve the tan you want or are the victim of sunburn. When the weather is affected this determines if you are able to enjoy the outdoors.

 

The first person to identify sunspots was the inventor of the telescope in 1610, Galileo. The method for counting sunspots was developed in 1848 by Johann Rudolf Wolf. This number is quite rightly known as the Wolf Number.

 

The observation of sunspots has occurred continuously since 1849 and began at the Zurich Observatory. How is a number computed? First, the scientists count the sunspot groups then the number of individual spots in a group. There are two agencies which determine the “official” sunspot numbers reported to the public and scientific world. The International Sunspot Number is determined by Solar Influences Data Analysis Center in Belgium, while the NOAA sunspot number is the result of counting by the National Oceanic and Atmospheric Administration.

 

Thanks to all this information we are informed as to what the weather will be and an Ultraviolet Index is produced so we can plan our day of “fun in the sun”.
