I found it very interesting to read Peter G3LTF report regarding 
conditions over the weekend.
It certainly shows the difference that can be experienced across the Globe.

At this QTH (QF22ro)
70cm on both days at Moon rise, Faraday was very close to 90 degrees
but within 5 degrees El it moved to ~45 followed by variations 
between 0 - 45 over ~5 minute periods.
In other words the "rapid" polarity swings resulted in deep QSB where 
the weaker station "came and went".
There was little Libration present and 70, and even with the QSB 
proved better operating than 23cm

23cm on both days was characterised by severe Libration, smear and 
deep QSB. Signals took on almost an
Aurora sound, although none was reported here that I am aware of. 
Most of the time I was forced to copy
in a wide bandwidth that made things difficult in working smaller stations.

The conditions (and activity) reflected upon a combined total of  96, 
which was 7 less than last year.
Recovering .. already sent YYY's to the dogs' snoring and have logged 
several others CWNR.

Next Year ? getting too old for this midnight caper ! (but I have 
said that for the last couple of decades!)

Excellent display of operating .. but please remember when hearing 
YYY DE VVV  KKK 333 UUU MMM then  follow suit and
also put an exaggerated space between the end and start of your call 
sign .. it helps so much during poor conditions.
