Sunspots may disappear in 2016
WASHINGTON: Sunspot activity is in constant decline and by the year
2016, they could disappear for decades, U.S. astronomers reported.
An analysis of 1,500 sunspots by Mathew Penn and William Livingston
of the Tucson National Sun Observatory in Arizona revealed that the
average intensity of the magnetic field of these sunspots decreased from
2,500 gauss to 2,000 gauss.
The level of the magnetic field of the earth is less than one gauss.
The causes of these reductions are unknown, but if the weakening of
this continuous force continues at the same rate, by 2016 it will reach
1,500 gauss, and with that intensity, magnetic fields may not form
sunspots. In Europe in 1645 and 1716, the absence of sunspots was an
event that coincided with the Little Ice Age, when Europe experienced
its lowest known temperatures. Sunspots are regions of the sun where
there is a lower temperature than surrounding areas and intense magnetic
