It is now being improved, increasing to 15 the total number of antennas and upgrading its control system.
The source of this activity, sunspot is growing rapidly.
From a constant stream of particles in the form of solar wind to the unpredictable bombardment from solar flares and coronal mass ejections, Earth often feels the effects of its stellar companions. Less noticeable are the sunspots crossing the solar surface, though they are related to the more violent interactions.
All of these fall under the definition of "space weather. According to NASA, sunspots are "the most visible advertisement of the solar magnetic field. The magnetic field lines become warped. When the magnetic field is strong enough — and twisted enough — jet streams Solar flares flowing currents create ropes of magnetism.
The pair are polar opposites, literally; think of them as magnetic north and south, with the rope acting as the magnet in between. View the full solar storm infographic here. If a single Solar flares stood alone in the night sky, it would be 10 times brighter than the full moon.
Similarly, sunspots might seem small when compared to the ,mile 1. However, ranging from 1, miles to 30, miles 2, km in size, they can reach the width of the planet Neptune, the smallest of the gas planets. But with a lifetime of anywhere from a few days to a few weeks, sunspots are far less permanent.
Sunspots do not appear in random locations. They tend to be concentrated in two mid-latitude bands on either side of the equator. They begin appearing around 25 to 30 degrees north and south of the center. As the solar cycle progresses, new sunspots appear closer to the equator, with the last of them appearing at an average latitude of 5 to 10 degrees.
Sunspots are almost never found at latitudes greater than 70 degrees. According to NASA, it takes approximately 11 years for the sun to move through the solar cycle that is defined by an increasing and then decreasing number of sunspots.
As it reaches the close of a cycle, new sunspots appear near the equator, while a new cycle produces sunspots in higher latitudes.
The cycles overlap; sunspots from the previous cycle can still develop even after sunspots from the new cycle appear. So solar scientists have a very difficult time saying exactly when one cycle ends and the next begins. As of earlysolar cycle 24 was approaching solar minimum.
The year cycle began in January and peaked inthe weakest solar maximum in yearsaccording to NASA. Despite the low level of activity, one of the largest sunspot regions ever was observed in Novemberreaching approximately the size of Jupiter.
Scientists measure the activity of the sun by keeping track of the number of sunspots appearing on its surface. Since the invention of the telescope, sunspot counts have been relatively constant.Jul 31, · The picture on the left shows a calm sun from Oct. The right side, from Oct. , shows a much more active and varied solar atmosphere as the sun moves closer to peak solar activity, a peak known as solar maximum, predicted for Jul 31, · The picture on the left shows a calm sun from Oct.

The first flare is an X, while the second is much more intense and rates as an X Higher numbers. Sep 06, · The NASA GIF shows the flares in quick succession and the difference in size is apparent. The first flare is an X, while the second is much more intense and rates as an X Higher numbers.
At a time in the sun's cycle when space weather experts expect less solar activity, our star is going bonkers with solar flares and coronal . Solar flares are a space weather phenomenon that can greatly impact our human bodies and lives, biologically affect us, and consequently affect our ability to cope.
