DESCRIPTION:ALMA has revolutionized the study of reionization-era galaxies
 . With the launch of JWST last year\, it is crucial to establish a local r
 eference sample of high-redshift "analog" galaxies covering essential UV\,
  optical and FIR emission lines that will soon become available in the upc
 oming JWST & ALMA era. A local (z=0.0040705)\, metal-poor (12 + log(O/H) =
  7.76) blue compact dwarf galaxy\, Pox 186\, exhibits the brightest CIII] 
 1908 emission (equivalent width 36 A) observed at any redshifts as reveale
 d by the HST/COS observations\, along with an extreme [OIII] 88/[CII] 158 
 (ca 10). This extreme CIII] is comparable to those observed in galaxies at
  redshifts of z=6-7\, when the reionization process is thought to be compl
 eted. I will present the analysis of UV nebular and stellar lines as revea
 led in this galaxy by the HST/COS observations. The work is very timely as
  reionization era galaxies galaxies are now being routinely detected with 
 the JWST.
