                                 monthly values   

COMMENT: Enhanced MUFs are being observed across all latitudes 
due to high levels of ionising EUV flux from the many sun spot 
regions on the visible Sun. These conditions are expected to 
continue for the next 3 days. Some isolated HF fadeouts may occur 
over the next few days due to the possibility of M class flares. 
There is a possibility of proton enhancement within the period 
resulting in high latitude ionospheric disturbances.
