[vsnet-chat 4869] Re: [AAVSO-DIS] Where is MMO 705?

["Jim Bedient" <bedient@hawaii.rr.com>]

I'm wondering if it might be CF Sct, B1900 position 18 43 00.6 -08 28 43
(about .5 degrees away from the position given for MMO 705).  It's listed in
the GCVS as ranging from 13.4 - 15.0, period 31.9415 days - pretty close.
Another possibility might be FM Sct, B1900 position 18 45 25.5 -08 38 05.
Its period is given as 1.451404 days, which is almost exactly 1/22 the
period given for MMO 705 in IBVS 512.

I'm no expert, just browsing VizieR late at night....
