Solar-terrestrial indices for 18 March follow.
Solar flux 177 and estimated planetary A-index 6.
The estimated planetary K-index at 0900 UTC on 19 March was 2.67.

Space weather for the past 24 hours has been moderate.
Radio blackouts reaching the R2 level occurred.

No space weather storms are predicted for the next 24 hours.


Magnetic field reversal now complete, the cycle has completed and should now be heading towards Cycle 25!


Did you know:  The Sun is almost 5 billion years old.

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


Server is down Server is down
SDO (straight-on view) [193Å] (SoHO 195Å) STEREO-A - to the East (looking around back of Sun)
Browse Latest Images STEREO B is of most interest to us B: Separation angle with Earth 15.15° = 1.18 days = 28.27 hours
A: Separation angle with Earth 8.92° = 0.69 days = 16.65 hours

STEREO - receiving the data.
Between April and June 2015 the datalink didn'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 had 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/probe failure or de-funding occurs.

How magnetism varies cycle-to-cycle: NORTH=WHITE, SOUTH=BLACK. [polarity is read from left to right]
Cycle 23 (May 1996): In the sun's northern hemisphere, all spots were S-N. In the southern hemisphere, all spots were N-S. 
Cycle 24 (Jan 2008): Northern sunspots are N-S while southern sunspots are S-N. 
This reversal occurs each time one cycle gives way to the next. It is called Hale's Law.
