Recent observations indicate that the symbiotic variable FN Sgr is
recovering from the current minimum, which has been suggested to be an
eclipse during a Z And-type outburst (vsnet-alert #443).

Judging from the available material, the fading started in middle to
late May. After staying at mv=13.5-14.0 for ~50 days, the object again
started a rapid rise in late July. The duration of the fading and the
shape of the light curve strongly resemble those of eclipses observed
during the recent (1988-1992) outburst of AX Per. Keep a close key on
FN Sgr during this important stage.
