  We report on the Lovers of Active Galaxies' (LAG) monitoring of the Seyfert 1
galaxy Markarian 279 from January to June 1990. The source, which was in a very
bright state, gradually weakened after the first month of monitoring: the
H-Alpha and H-Beta flux decreased by 20% and 35% respectively, and the
continuum under H-Alpha by 30%. The luminosity-weighted radius of the broad
line region (BLR), as derived from the cross-correlation function, is of the
order of 10 light days. This result is very uncertain because the features in
the light curves are very shallow, but it is unlikely that the radius of the
BLR is more than 1 light month. The profile variations of H-Alpha confirm that
the prevailing motions are not radial. The data of the present campaign and
those obtained in previous years, when the source was in a much weaker state,
show that the red asymmetry of the Balmer lines correlates positively with the
broad line flux. This new effect is briefly discussed.
