Topband: Ionospheric and geophysical data versus 160m propagation conditions

[py2cw160 "Mac"]

Hi folks
                Is there any correlation between top band propagation =
conditions
versus solar activity, ionospheric conditions, geophysical activity, =
etc???
Presently, we have a lot of information such as real time solar flux =
indices etc. available in the web. Which are the most relevant to be =
watched to the objective of "go to the shack" looking for "openings" in =
top band???
Who made an statistical analysis comparing better 160 propag. cndx
versus those indices? Back in the seventies i tried to correlate WWV
data to my log (as pt2fru). I remember very well when qso'd in phone =
with 100W many dx stations during a "geomagnetic storm", but was the =
only opportunity and this is not statistically "safe".
                                                                         =
                             py2cw "Mac"
