Observations of aurorae realized by the Polar Geophysical Institute on the Kola Peninsula, and a brief description of methods of primary processing of observations, and ways to produce information are presented. Results of the primary processing of observations in the Lovozero observatory, located in the central part of the Kola Peninsula, were used to study the diurnal distribution of aurora appearance. It is shown that in the years of solar activity maximum (2000-2002), aurorae are most likely registered in the interval from 21:30 MLT to 03:30 MLT with a maximum in 00:30-01:30 MLT. Histograms of the probability of aurorae observations in different parts of the Kola Peninsula during the years of both maximum (2000-2002) and minimum (2007-2009) solar activity depending on the local K-index of magnetic activity are constructed. The obtained results can be used to select the time intervals and the level of magnetic activity of the most favorable for the observation of aurorae in different areas of the Kola peninsula.
