COMMENT: SWS HF Communications Warning 34 was issued on 14 April 
and is current for 15 Apr only. Maximum usable frequencies (MUFs) 
on UT day 14 Apr were near monthly predicted values to slightly 
enhanced. HF conditions were degraded for southern Australian 
region during local night hours last night due to geomagnetic 
activity induced from a CME. However, due to the brevity of geomagnetic 
activity on 14 Apr, forecast moderate MUF depressions are generally 
now not expected, with mild depression possible after local today 
for southern region Australia only, then recovering.
