The T-index chart:
This image shows the DIFFERENCE between current OBSERVED HOURLY conditions and PREDICTED MONTHLY conditions for the Australian region. The colours blue, green, yellow, red, correspond to "enhanced", "normal", "mildly depressed" and "depressed" conditions respectively. Depressions and enhancements are with respect to the IPS predicted monthly T index for that month.

The real time Ionosonde. Sorry I can't embed this active picture here. Go to the link page and select "Hobart" to
see the layer conditions  and find out the vertical MUF.  Adjusting the "Amp Threshold" level up will mask out weaker reflections.

Legend:  White solid line indicates monthly predicted foF2.  White dashed line indicates monthly predicted foF2 +/- 30%.
Red solid line indicates hourly observed (autoscaled) foF2 from that station.  Yellow solid line indicates sporadic E (foEs).
Blue squares indicates hourly autoscaled foF1 from that station.

Propagation map
See the predictions of what frequencies go where. Select "Amateur" instead of "Arbitary". Click on your location so that the
word "BASE" appears.  Then click beyond the area you are interested in and drag the mouse diagonally across the area to select
an area. Then click on the "Do Prediction" button. A new page opens on your browser with links to 4 images to cover the
whole day.  A similar series of maps like the picture above.

From What the trends are:
Black line is solar flux, 60 is about as low as I have seen it at solar minimum.
A good sunspot cycle can see numbers over 160
Blue line is planetary A index, a good measure of how disturbed the ionosphere
 is. Below 10 gives stable propagation conditions. 
Red Line is sunspot numbers.
