There is a long tradition of the Solar Patrol (SP) service at the Ondřejov observatory (AI CAS). This service observes the Sun in white light and in the H-alpha line. The results are used in the scientific research of the Solar Department and they contribute to the world net International Space Environment Service (ISES) and their member the Regional Warning Centre Prague (RWC Prague) as station No. 31516, and to Solar Influences Data Analysis Center (SIDC) in Brussels. Sunspot drawings and synoptic white-light images are produced daily, depending on weather and technical conditions. The SP compiles and publishes a daily solar activity forecasts and weekly solar-activity forecasts. Weekly forecasts of the solar activity are made since 1978 and are distributed through public institutions in the Czech Republic and abroad.
