Remarks: We ask for a coordinated observation with IXPE, that is currently scheduled between april 30 and may 2 (100 ks exposure).
ToO: Y
Coordinate Observation: Y
Observatory: IXPE
Description: Cyg X-2 is a known variable Z source. A joint observation with the 100-ks IXPE exposure would ensure that the source is seen in the same spectral and flux state by the two instruments, maximizing the scientific output.
