Dear Astronomers,

yesterday, 24th of April, during my observing run at the SAAO in South
Africa I watched the fading LYHya for about 2 1/2 hours (UT 21:44 to 0:17)
yesterday night and found nice Superhumps in the light curve confirming it
to be an SU type dwarf nova. The humps have an amplitude of about 1mag in
V and 0.5 mag in I.

Sonja Vrielmann.
