The Solar Cycle

Although it may look unchanging from the ground, the sun actually has a long-term pattern of change called the sunspot cycle. During one cycle the number of sunspots, and solar activity, increases and then decreases again. This process is driven by the flipping of the sun's poles.

so basically: suns centre is only 6000 degrees hot, but the surface is some million degrees hot. sun flares are like like electrical pulses that throw out that hot stuff and wants to kill our satellites.

Hope my snotr connection is terrestrial in 5 years

So basically we cannot trust on solar flares to EMP Skynet in 2020 and save our butts.

Three men were in a NASA conference room to decide how to spend $10 billion.
“I think we should put our men on Mars!” said the first man.
“Ooh, good idea,” said the other two.
“I think we should put our men on Venus!” said the second man.
“Ooh, good idea,” said the other two.
“I think we should put our men on the Sun!”
“How are you going to do that?”
“Easy. We go at night.”

And those big flares make Aurora Borealis when they hit Earth's athmosphere.

They can't tell what weather will be tomorrow around here, and they expect us to believe they know what the weather on the sun will be in 2030.
