COMMENT: Improved HF conditions observed during local day and 
night due to increased ionising EUV/X-ray enhanced by numerous 
active regions on the disc. Region 2056 represent a high probability 
of M class flares and moderate short-wave fadeouts (SWFs). Expect 
these conditions to prevail over the next 24 hours. Possible 
disturbed ionospheric support for Antarctic regions 10-11 May.
