Solar activity is expected to be at the R0-R1 levels on 07-Dec. The solar wind speed is initially expected to be light with an increasing trend from late 07-Dec to 08-Dec due to a coronal hole wind stream. Geomagnetic conditions are expected to be at the G0 level, with a mild increase in geomagnetic activity expected over 07-09 Dec. Isolated G1 periods are possible during this interval. Australian regional maximum usable frequencies are expected to be near predicted monthly values, with mild depressions possible 08-09 Dec for the southern Australian region. Shortwave fadeouts are possible.
