FY Vul entering a low state or standstill?

FY Vul 1000 day AAVSO light curve

The NL star FY Vul seems to have entered a low state or perhaps a standstill-like episode. Please continue monitoring it daily.



It’s all about the  standstills, those episodes where the star gets stuck at a mid-point between maximum and minimum. If it doesn’t exhibit standstills it isn’t a Z Cam star.






AM Her stars in need of further investigation
