Our long campaign on IM Nor has ended, and here's what came out:
Comments solicited. Submission to a regular journal is still a ways
off. Since there's some pretty speculative stuff in there, I've got to
sit on that for a little while first. What seems exciting on a Monday
can sometimes look pretty spacey by Friday!
But I've sure gotten seduced by these novae! (Supersofts too, but there
are precious few them in our galaxy.) So here's a list of novae which I
think are promising for Oct-Nov observing.
V392 Per. Lots of good data from USA observers (especially western USA
- mainly Richard Sabo and Waly Cooney). Even more from Joe Ulowetz, and
I use his data for calibrating everyone since his location is central in
North America. But not much from Europe, which we really need, because
the periodic-signal search in this star is TRICKY - we just need to
splice together runs over a wide range of longitude. 15th mag, well
placed in the sky... and a star which seems destined for greatness (the
only dwarf that became a nova!
There are some other (now quiescent) novae which are good targets in
Oct-Dec. Here they are: V597 Pup, CP Lac, DN Gem, and maybe KT Eri. I
don't know much about these - maybe just or two of them really is a good
target. Use your judgment.
I guess it's too late for V1974 Cyg. But if you can get ~3 hours on
this star, that's the best northern target of all.
