2003 July 25/27: Short but productive sessions in summer nights about midnight mostly variables [including emission line stars] at dispersion of 3.23A/pixel via the WPO spectrograph using the B band line in red for common reference. The series begins with variable gamma Equ - a pulsating star with a remarkable short period [both spectrum and light curve] in 12.5m and unusual rare earth element spectrum.
