Scientific paper

Spectroscopic data for the QSO H1340 no. 10 are reported and discussed in terms of known active objects. The FWHM of the Lyman alpha line was measured at 1500 km/sec, which is far below other high-z QSOs. However, the C IV emission line is similar to that observed in QSOs and in narrow-line profiles of Seyfert 2 galaxies. An excess luminosity f H1340 no. 10 is suggested to be due to the action of a gravitational lens. It is also possible that H1340 no. 10 is a bright, narrow-line object like a Seyfert 2 galaxy, or a QSO with atypical narrow emission lines. IR observations are recommended for distinguishing the actual classification of the object by obtaining broad-line magnitudes.
