I was able to copy XSR 166.5 last night and very poor copy of WA & VD 185.300
So conditions are still bad!

MIDDLE LATITUDE AURORAL ACTIVITY WATCH 07-10 OCTOBER

      Some persistent and powerful auroral substorm activity has been
occurring over the last few days. The activity is in response to
interplanetary magnetic field, which has been oriented in a particular 
way
that promotes the occurrence of auroral substorm activity. What is 
unusual
about this activity is that it has been persistent now for several 
days. A
strong substorm over North America last night between 06:00 and 09:00 
UTC
(2 am and 5 am EDT) resulted in some impressively bright auroral 
activity
over a good portion of the north-central United States. Experienced 
aurora
"hunters" in Northern Germany have also been able to consistently 
photograph
weaker levels of activity over the last 2 consecutive nights. This has 
been
possible due to the enlarged size of the auroral oval.

      Similar sporadically strong activity is expected to continue over 
the
next 2 to perhaps 3 days. The possible arrival of one or two additional
coronal mass ejections may further help to improve the potential for 
substorm
activity over the next 48 hours.
