Both SOHO and ACE are located at the L1 point between the Earth and Sun. This is about 1.5m km from Earth (or 932,000 miles).

From this vantage point Solar wind data can be detected about 45 to 60 minutes before reaching Earth.

SDO - Soft X-ray image

SDO (straight-on view) [193] (SoHO 195) STEREO-B - to the East (looking around back of Sun)
Browse Latest Images STEREO B is of most interest to us B: Separation angle with Earth 163.04° = 12.68 days = 304.34 hours
A: Separation angle with Earth 169.69° = 13.2 days = 316.75 hours

STEREO - receiving the data.
Between April and June 2015 the datalink won't reach the Earth. 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 survive ecllipse and the increasing solar activity, then they will remain extraordinary solar sentinals. Antenna pointing is restricted, so signal recovery may be marginal.

-90/+90 coverage was achieved in February 2011. With SDO/SoHO that should ensure 360 coverage until 2019 - or until instrument failure or de-funding occurs.

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.
