Weak ionospheric support over the UT day.
Minor absorption observed after 17UT due to
elevated proton fluxes.
PCA Event : No event.

2. FORECAST (15 JULY - 17 JULY)
Date T index Conditions MUFs
15 Jul 55 Normal Near predicted monthly values/depressed

16 Jul 55 Normal Near predicted monthly values/depressed
10-30%.
17 Jul 60 Normal Near predicted monthly values/depressed
10-20%.
COMMENT: Variable propagation conditions observed Equatorial/Aus
regions with moderate night-time MUF depressions following onset
of an anticipated solar wind shock event. Continuing poor ionospheric
support Antarctic region with mild absorption observed due to
shock-related proton deposition. Chance of isolated short-wave
fadeout events. Possible ongoing disturbance days one and two
due to CME impact from the X-class flare observed late on Jul
12.
