Dear colleagues,
Patrick Wils analyzed the NSVS data and revealed the types and periods
of MisV1384 - MisV1387.
Star Type Period Epoch
-----------------------------------
MisV1384 EA 1.1609 2451299.83
MisV1385 RRAB 0.47414 2451504.78
MisV1386 EW 0.3406 2451520.82
MisV1387 EW 0.2628 2451520.83
Patrick Wils also commented that MisV1385 has been found before by
Wils P., Lloyd C., Bernhard K. (MNRAS 368, 1757).
