MS patient admittance rates were correlated with the solar and geophysical data.
Increase in the admittance rates 7–8 months after intense geomagnetic activity.
More prolonged increase in the admittances with prolonged helio-geomagnetic events.
Instant rise in the admittances the following month after storms with DST <−150 nT.
Highest numbers of admissions 7–8 months after storms with DST index <−200 nT.
