        There is another (new) variable in the vicinity of V915 Sgr : -
MisV0562 (2000) 18h41m16.71s -29 4'41.7"  range 11.8-13.8C.  
This appears to be catalogued as GSC 6870.01256 (m=12.95). Type is not known,
but is worth keeping in mind when scrutinizing observations of stars in
this region. It is only 1.5' south of CoD-29 15226 (Brian Skiff's red star).
