Solar Wind's Effect on Earth☆

NASA's Solar Dynamics Observatory is monitoring a dark rift in the sun's atmosphere. The spacecraft's Atmospheric Imaging Assembly (AIA) took this extreme ultraviolet picture just hours ago.
A new computer model suggests the next solar cycle will be more active than the previous one, potentially spawning magnetic storms that will be more disruptive to communication systems on Earth.

The next sunspot cycle will be 30 percent to 50 percent more intense than the last one, scientists said Monday.

The cycle will also begin a year later than expected, in late 2007 or early 2008, and peak around 2012, said Mausumi Dikpati of the National Center for Atmospheric Research in Boulder, Colo.
Accurately predicting the intensity of the sunspot cycle, which occurs about every 11 years, allows scientists to anticipate solar storms. They are caused by solar flares, or giant eruptions that burst from the surface of the sun.
Highly charged material ejected from the sun during solar storms causes power outages and disrupts satellite communications that can affect everything from taking cash out of an ATM to chatting on a cell phone.
It's a "coronal hole," a vast region where the sun's magnetic field has opened up and allowed the solar wind to escape. Indeed, a solar wind stream flowing from this hole is heading toward Earth, due to arrive on June 7th or 8th. High latitude sky watchers should be alert for auroras on those dates.
The solar wind creates the heliosphere, a vast bubble in the interstellar medium that surrounds the solar system. Other phenomena include geomagnetic storms that can knock out power grids on Earth, the aurorae (northern and southern lights), and the plasma tails of comets that always point away from the Sun.

Is it solar wind or solar charged particles?

Good information!
