				<para>
   We present CCD photometry and spectroscopy for stars in Lucke-Hodge 9 and 10,
   two adjacent OB association in the northwest corner of the LMC. Our catalog
   contains UBV photometry (complete to ~18min in all three filters) for 795
   stars and BV-only photometry (complete to ~19min in both filters) for an
   additional 434 stars.</para></description>
