[vsnet-chat 4868] Where is MMO 705?

["Mati Morel" <morel@ozemail.com.au>]

While browsing through some old issues of IBVS, I came upon number 512 (1971
January 28), in which L.J.Robinson and M. Harwood report the discovery of a
new long-period eclipsing binary, provisional name MMO 705. I assume MMO
means "Maria Mitchell Observatory".  The star is located, according to IBVS
512, at (1900) 18h45.0m  -8° 35'.  The basic parameters of this system seem
well established - range 13.3-15.6p,  period 31.9384d. A small finder chart
is given.  However when I compared it with a Guide7 plot it did not match
very well. I checked other possible positions, north and south, to no avail.
The coordinates seem to be in error.

Interestingly, no matching variable could be found in the GCVS, in Scutum or
nearby constellations.  It appears that MMO 705 is yet to receive a GCVS
name; possibly the identification problem was noticed years ago, and is yet
to be solved.

Does anyone have further information on MMO 705?
