NASA Warns Sun Activity Too Low This Year
NASA has recently come up with a bizarre finding. Warning has been raised by the space administration that the sun has been going through something unexpected.
It has told that solar activity is highly low. However, the same was expected to be at the maximum this year. The year was being hoped to be `solar maximum' year i. e. the 11-year sunspot cycle's peak.
The Sun's Earth-facing surface was captured on February 28, 2013, by the Helioseismic and Magnetic Imager (HMI). The Imager on Solar Dynamics Observatory of NASA observed that the otherwise clean face this time had a few small sunspots.
The same is often questioned with a number of spots during peak solar activity. It has been found that the observation of the apparent lack of activity of the sun has startled as well as perplexed experts. Many of them have been wondering if the picture has been captured wrongly by NASA.
On the other hand, Solar Physicist Dean Pesnell from Goddard Space Flight Center of NASA was of the belief that the discovery was solar maximum. He said that the same is possibly looking different from what was expected since it was double-peaked.
NASA was quoted as saying, "Sunspot numbers are well below their values from 2011, and strong solar flares have been infrequent".
