Tom is correct.
 It's probably unlikely that they're going to be on 160M at their 
sunset....they're going to be on other bands and their operating 
pattern, so far, has confirmed this.
 I would guess that the time your most likely to work them is 1 or 2 
hours before your sunrise with sunrise +/- 30 minutes being the peak time.

So, it looks like there is a window of about 6 hours of darkness.
 
 
Any time in that window is a chance.
 
I have also read that there is sometimes an increase in signal strength
 during the terminator.  It's not clear to me if that means the 
terminator
at the DX location or my QTH.
 
 
 Either one. There are also peaks we miss that are not at either 
terminator. They may not be as frequent, but they are there at odd 
times during darkness.
 When I had daily skeds with VK3ZL and ZL3REX, we would frequently have 
peaks only during off times.
 
Assuming 3D2C is transmitting on 160 throughout that period of 6 hours,
when am I more likely to work them?
 
 
When they are on. :-)
