(cba:news) Recent CBA targets ('Joe Patterson' via CBA News) [2026-09-10T19:00:19Z]


Hi CBAers,

We're trying now to closely track the high-luminosity probable supersofts in the night sky (QR And and V Sge). They're elusive, because they have periods near 6, 8, 12, or 24 hours - so we have to disentangle them with LONG runs... longer than the 6-8 hrs one observer can manage.

The main stars in question are V Sge and QR And. Both plenty bright. Gordon Myers has helped this period-finding search with runs from eastern and western Australia (Siding Spring and Perth). But to nail the period over a long baseline, we still need more long runs from western Europe and western USA.

Unlike dwarf novae, these stars are always "high state". But some of these high states show deep eclipses (about 1 mag), while others just flicker around. To tell them apart, long runs are needed.
