This paper presents the effects of a weak geomagnetic storm event on 17 January 2013. While the K p index reached a maximum of only 4, this event still caused severe disturbances for Global Navigation Satellite Systems (GNSS)‐based positioning services at high latitudes. We present data from the Norwegian Mapping Authority's Real Time Ionospheric Monitor, based on a dense network of geodetic receivers and scintillation indices from scintillation receivers located in Norway. In northern parts of Norway, the centimeter positioning service was severely disturbed for hours. Service‐monitoring measurements showed that the effect was significantly worse for a receiver far away from the nearest network reference station.
