Divide the number shown here by 100 to calculate the number of MHz that MUF is up or down compared to the last 60 days at the current time. Raw data can be found here for Wallops Island ionosonde. |
Cycle 24 predictions: (I) (II) (III)
Only 12 months from solar maximum, but very poor.
Did you know: The Sun is plasma and not a solid like the Earth, the Sun rotates faster at the equator than it does at the poles. .

B: Separation angle with Earth 141.45° = 11 days = 264.04 hours A: Separation angle with Earth 136.64° = 10.63 days = 255.06 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 SoHO that should ensure
360° coverage until 2019 - or until instrument failure or
de-funding occurs.
