Toward Asia check 80 meters from 0800 to 1330z, 40 meters from 0700
to 1430 and 30 meters from 1400 to 1600.  20 meters looks good from
2100 to 0030.  17 meters may have an opening around 2200.
 
South America looks good from 2330 to 0930z on 80 meters and 2300 to
1000 on 40.  Check 30 meters from 2200 to 0300 and again around
1030.  On most days 30 should be open past 0300 to 0730.  20 looks
good around 1430 and again from 1900 to 0030 and 17 meters from 1500
to 2300.  15 meters should be open from 1600 to 2130.  Check 10
meters around 1800.
 
For Europe, 80 meters should be open from 2300 to 0700z and 40
meters from 2200 to 0500 and 0700 to 0900.  Check 30 meters around
