Solar Cycle 24 – Solar Activity To Affect GPS Accuracy
Solar Cycle 24 progress
Evidently everyone has heard meteorological reports this week about a solar storm coming. This is a part of the new solar cycle, Solar Cycle 24, which proves that the solar activity is going to increase over the next few years. According to the most recent reports the severe solar activity could affect the accuracy of GPS navigation and tracking devices.

IA. Analysis of Solar Active Regions and Activity from 05/2100Z to 06/2100Z: Solar activity was low. Region 1093 (N12E45) produced a C1 flare at 2135Z. New region 1095 (S19E34) was numbered today.
IB. Solar Activity Forecast: Solar activity is expected to be very low with a chance for an isolated C-class flare from Regions 1093
and 1094 (N26W71).
