Abstract
J. Schramm, J. V. Linde, U. Borgeest, and L. Nieser, Hamburg Observatory, telex: "Since 1989 Oct., we have carried out a photometric monitoring program of 0836+710 in the R band at the Calar Alto 1.23-m telescope. Until 1991 Oct., only minor variations of 0.05 magnitude had been detected. Since 1992 Feb. 6 an increase of 0.7 magnitude, reaching a maximum on Feb. 16.88 UT, has been observed. Since then, the quasar has faded again by 0.2 magnitude."
