Hi CBAers,
With the dark of the Moon, it's an excellent time to get LONG runs on
V1674 Her. At mag 17.7, it would normally be a challenge for us. And
the 8-minute spin signal is quite strong, appearing even in short or
mediocre runs. But the 3.6 hour orbital signal is weak, requiring long
runs in fair-to-good conditions. Most of all, the orbital signal
requires long runs, since it's weak and has no sharp features (like a
true WD eclipse) Now, with the star transiting near midnight, is an
excellent time to get such runs, assuming weather cooperates.
We're also re-awakening "Nova Sco 1437", which we dropped a few years
ago after another bauble (I think "Maxi") caught our eye. I'm not sure
what the variable-star name is. Can someone supply it?
I had hoped to attend this week's SAS convention in California. My
health has been subpar (not in the golfing sense), so a long trip seems
ill-advised.
Write!
joe
