2003 July-Sept: Short sessions in summer nights about midnight to include variable Rho Cas [featured in S&T July 2003 article All Eyes on Cassiopeia] at dispersion of 3.23A/pixel via the WPO spectrograph using the B band head for common reference plus some ultra low 50-25A/pixel via the Rainbow Optics grating in non-objective mode.  Link to Dr Alex Lobel - principle Harvard investigator for recent Rho Cas paper and amateur observations including spectra - no substantial change noted at WPO for Rho Cas from 2003 July 7 - Sept 23.
