Observing Campaign #648: Semiregular variable reclassified as symbiotic: outburst of ASASSN-V J195442.95+172212.6 = Vend47 (Sge)

Abstract: ASASSN-V J195442.95+172212.6, originally classified as a semiregular variable, has been reclassified as a symbiotic variable as a result of its being discovered in outburst by Robert Fidrich during the course of his “Vendégcsillag-kereső” (Guest Star Hunter) nova patrol program. Subsequent spectroscopy confirmed the nature of the object as a symbiotic variable.

Justification: Observations of all types (visual, CCD, DSLR, PEP, spectroscopy) and multiple bands as instrumentation permits are strongly encouraged as the outburst progresses. Its range prior to this outburst was ~12.3-13.2V.
