Happy New Year 2016

A few JT65A QSOs over the last couple of hours on 15m and 17m. Hopefully many more of the year.

Solar-Terrestrial Data

The Solar Flux Index (SFI) is a gauge of solar particles and magnetic fields reaching our atmosphere. Higher numbers mean more solar wind is reaching the earth thus better propagation.

The K-Index (or Boulder K) is a gauge of geomagnetic activity relative to an assumed quiet-day curve for Boulder,Colorado. Falling numbers mean improving conditions and better propagation particularly in northern latitudes and areas where aurora activity can occur. (The further you are from Boulder,Colorado, the less exact this information will be.)

The A-index is simply an index of geomagnetic activity derived from a scaled average of the previous 24 hours K-index readings. Use this as a reference for general conditions on the bands. Lower A index means better propagation.
