[vsnet-chat 1045] Re: NSV 11280 (vsnet-chat 1033)

Hi all,
I forward a message I have received from Ronald Downes, concerning
NSV 11280. I have confused the identities of _Aql1_ and _Aql_ = NSV 11280.
The Downes et al Atlas of Cataclysmic Variables is correct. The chart I was
examining (Aql1) refers to RX J1940.2-1025, NOT NSV 11280.  No chart is given
for NSV 11280.
I apologize for any inconvenience caused.
Regards,
Mati
