SS Cyg
€SS Cyg
observed almost
continuously since 1896 (AAVSO)
€Brightness history shows a variation
on a timescale
of ~50 days,
€Unequal length maxima, no strict periodicity but remarkably regular
timescale
€varying
between
mv~8 and mv~12
(a factor of 40)
€Less
than the amplitude seen in novae, hence known as Dwarf Novae
