Ionospheric Forecast

(last updated 16 Jan 2018 23:30 UT)

Date T index MUFs 17 Jan 0 Near predicted monthly values 18 Jan 0 Near predicted monthly values 19 Jan 0 Near predicted monthly values COMMENT: HF conditions stayed mostly at normal levels in Australian region with some periods of small MUF enhancements as well as period of small MUF depressions in the Northern parts of the region. Periods of Sporadic E blanketing were also evident. Mostly normal HF conditions may be expected in the region for the next three days (17 to 19 January) with some possibility of minor MUF depressions as the solar activity is expected to stay at very low levels during this period, which may result in the weakening of ionising radiation.
