Perusindeksit olleet loistavat pitkään, mutta kelit ei kummoiset. Onko jokin viisari väärään suuntaan vai koko ionosfääri väärässä paikassa?
Solar activity is expected to be at very low levels.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal levels.
The geomagnetic field is expected to be at quiet levels 11-14 February. Activity is expected to increase to quiet to unsettled levels, with isolated active conditions, on 15 February due to a recurrent coronal hole high-speed stream (CH HSS). Activity is expected to decrease to quiet levels during 16-21 February as the HSS subsides. Activity is expected to increase to quiet to unsettled levels, with isolated active levels, on 22 February due to another CH HSS. Isolated minor to major storm conditions are possible at high latitudes during this period. Activity is expected to decrease to mostly quiet levels from 23 February - 09 March.
