COMMENT: Data gaps from Cocos Island and Niue Island limit our
ability to determine the ionosphere support for the Equatorial
region. Some mild depressions were observed for Southern/Northern
regions during 12 April otherwise conditions were mostly normal.
MUFs are expected to be mostly near predicted monthly values
with slight depressions at times for the next 24 hours. There
is the chance of short-wave fadeouts over the forecast period.
