A closer look at f∝1m leads to the post "Twinkle, Twinkle Little Stars" dated 25 Jul 2014,
f=12π√gprp
and Venus adjusted surface gravity, gv=0.02586kms−2 and its radius rv=6052km which give,
f=12π√0.025866052=0.0003290s−1
which is about one pulse in 3039.6s or one pulse in 50.66mins. Do not confusion this pulse with atmospheric disturbance.
