COMMENT: Depressed conditions observed in southern Aus/NZ region

conditions now expected to be better than originally forecast
for 31 May due to lack of geomagnetic activity following recent
solar mass ejection arrival overnight. Depressions of 10-20%
likely to be experienced for southern region sites after local dawn
this morning, then improving. Northern region MUFs expected to remain
near predicted monthly values.
