Solar activity has been at very low levels on 17 March. The two CMEs
mentioned in the report yesterday, do not seem to have any
geoeffective component. Due to the continued coronal hole effect solar
wind stream is still going strong. Solar wind stream is expected to
remain strong on 18 March and then gradually weaken over the following
two days thereafter. Very low levels of solar activity, with some
possibility of isolated C class activity, may be expected from 18 to
20 March. Due to the continued effect of the coronal hole, geomagnetic
activity reached up to unsettled and active levels today with isolated
minor storm periods at high latitude locations. This coronal hole
effect may continue to raise geomagnetic activity to unsettled and at
times to active levels on 18 March. Geomagnetic activity is then
expected to gradually decline to unsettled through to quiet levels
during 19 and 20 March. Mostly normal to fair HF conditions were
observed during the last 24 hours. As anticipated, periods of minor to
moderate MUF depressions were observed on 17 March due to continued
increase in geomagnetic activity levels. Nearly similar conditions may
be expected on 18 March. HF conditions are expected to return to
normal levels on 19 and 20 March.
