COMMENT: For the UT day, 25 April, MUFs were enhanced over the
equatorial and low latitude regions. Mild depressions occurred
over the mid-latitude and southern Australian regions. The outlook
for the next two days (26 and 27 April) is for similar MUF gradients.
The southern and mid-latitude degradations of MUFs are due to
the storm induced ionospheric depression, extending from the
polar into the mid-latitude regions. MUFs to expect recover to
mostly near monthly predicted level by 28 April
