90 hours STEREO is a short term mission. The expected life is two years. This is because the datalink won't reach the Earth soon. Why? The angle B-Earth is gradually increasing, at the rate of about 0.3 degrees per month. When this gets too large, the signals will have to graze the Sun to reach Earth. If the satellites should survive the ecllipse and the increasing solar activity, then they may become extraordinary sunspot sentinals for us. Also, antenna pointing is restricted, so signal recovery will become an issue. Let's hope that they last for as long as SoHO (wishful thinking!). |

How magnetism varies cycle-to-cycle: NORTH=WHITE, SOUTH=BLACK. [polarity is read from left to right]
Cycle 23: In the sun's northern hemisphere, all spots are S-N. In the southern hemisphere, all spots are N-S.
Cycle 24: Northern sunspots will become N-S while southern sunspots will become S-N.
This reversal occurs each time one cycle gives way to the next. It is called Hale's Law.
