Abstract
We report on spectral observations of the night sky in the band around 900 Angstrom where the emission line in the Sciama model of radiatively decayin g massive neutrinos would be present. The data were obtained with a high-re solution, high-sensitivity spectrometer flown on the Spanish satellite MINI SAT. The observed emission is far less intense than that expected in the Sc iama model.
