activity forecast for the period May 8 - June 2, 2015
Geomagnetic field
will be:
quiet on May 20 - 23, 26 - 27
mostly quiet on May 11, 24, 28,

quiet to unsettled on May 19, 25, 29, 31
quiet to active on May 8 -

active to disturbed on May 10, 12, 15, June 1
disturbed on
May 13 - 14
Amplifications of the solar wind are still mostly
unpredictable,
but some peaks are expected on May 14 - 18, 20, 22, 30 -
31
and June 2 - 3.
Remarks:
- Reliability of predictions is still
reduced, disturbance rate
is and remains elevated.
- Parentheses
indicate a lower probability of increased activity.
