[vsnet-symbio 126] NSV25735 = StHA190



NSV25735 = StHA190

   According to astro-ph/0102192, Munari et al. repoorts the discovery
of bipolar and highly variable mass outflow in NSV25735 = StHA190.
Such phenomena have been notably known in R Aqr, CH Cyg, MWC 560 = V694 Mon,
RS Oph and Hen3-1341.  NSV25735 = StHA190 is the first case that a yellow
symbiotic hosts such outflows.  Since this object is very bright, detailed
observations are strongly encouraged.
