University report that 2008fq (cf. CBET 1507) was observed with the
ESO Very Large Telescope on Sept. 18 UT.  Spectra were taken with the
FORS instrument in polarization mode (PMOS) using the GG435 filter.
Preliminary reduction shows 2008fq to be a young type-II supernova.  The
spectrum exhibits conspicuous H-alpha and H-beta lines with a rather
unusual narrow P-Cyg profile with the absorption minimum blueshifted by
670 km/s and superimposed on a more diffuse absorption that is itself
blueshifted by more than 7500 km/s.  The Na I line show similarly complex
profiles.  These data suggest the existence of multiple shells in the
supernova ejecta, caused probably by ejecta-CSM interaction.
