COMMENT: Slight improvement in HF conditions observed on 28 June 
due to increased ionising EUV/X-ray enhanced by increased active 
regions on the disc. The F10.7 cm solar radio flux and ionospheric 
T indices have been trending upwards, outlook is for a strengthening 
ionosphere. Possible disturbed ionospheric support for Antarctic 
regions 29-30 June.
