LZ Mus = Nova Muscae 1998

LZ Muscae was discovered by W Liller on December 29, 1998, at mv = 8.5. It was established that LZ Mus was photographed by O’Meara two nights before the nova was first spotted by W Liller at around magnitude 8.0 (+/- 0.2). The object is classified as a very fast nova.

My first observation of LZ Mus was on December 31 at magnitude 10.4. My visual observations are detailed below and cover the next 170 days until the nova faded. As seen from the light curve LZ Mus displayed oscillations with time scales of several days, and an amplitude of one full magnitude during days 27-60 after maximum light. Variations of 0.5 mag. were visible to day 88 after which the nova continued to slowly fade.
