The ionospheric Vertical Total Electron Content (VTEC) is extracted from the near-real time European VTEC maps at 3 different locations (Figure 1):

a) Northern part of Europe (lon: 5°; lat: 61°, top)
b) Brussels (lon: 4.5°; lat: 50.5°, middle)
c) Southern part of Europe (lon: 5°; lat: 36°, bottom)

Figure 2 shows the VTEC (in red), the VTEC normal quiet behaviour (median of the 15 previous days with its standard deviation in grey), and the variability of the VTEC during the 5 minute time span of the map (in blue, right scale).

Figure 3 shows the VTEC difference (in green) and relative difference (in blue, right scale) with respect to VTEC normal quiet behaviour.
