  A highly and rapidly variable bipolar mass outflow from StHa 190 has been
discovered, the first time in a yellow symbiotic star. Permitted emission lines
are flanked by symmetrical jet features and multi-component P-Cyg profiles,
with velocities up to 300 km/sec. Given the high orbital inclination of the
binary, if the jets leave the system nearly perpendicular to the orbital plane,
the de-projected velocity equals or exceeds the escape velocity (1000 km/sec).
StHa190 looks quite peculiar in many other respects: the hot component is an
O-type sub-dwarf without an accretion disk or a veiling nebular continuum and
the cool component is a G7 III star rotating at a spectacular 105 km/sec unseen
by a large margin in field G giants.
