Z ANDROMEDAE
H. Netzer, Tel Aviv University, communicates: " The long expected
outburst of the symbiotic star Z And occurred during or before 1982
Aug. Spectroscopic observations at the Wise Observatory reveal very
noticeable changes in the emission lines. Most of the strong lines
have increased by a factor of two compared with their 1981 intensities,
while the red continuum has remained unchanged. Subsequent observations
in Sept. and Oct. show a rich Fe II spectrum not present a year earlier
and a sharp Balmer jump."
