D/D/D/S OMM-001 FS-511.
S is shifted further north on this OMM than the others, and is also significantly stronger. Can also make out one of the additional D's south of the primary. OMM-002 D/S has a more centered S, which is not visible above the D. The D in OMM-002 is also shifted slightly higher than OMM-001 (your example).
