Dear fellow astronomers, this one might be of interest for Sun spectators.
The INTER-SOL Program (ISP) has been established by Reinhard Wiechoczek - also founder of the Public Observatory Paderborn, Germany - in the year of 1977 after several preparatory tests during 1976. 1) Surveying the different Sunspot phenomena, IS (INTER-SOL Index) should give more detailed information about the activity than the common international SIDC (Brussels) which is deriving just one concluding Sunspot number "R". 2) IS should be comparable to terrestrial statistics of any kind for possible research of solarterrestrial phenomena. The task of ISP is to draw up a document of the Sun activity. Since most of the terrestrial statistics dealing with all aspects of life are based on monthly or yearly terms, the IS data are smoothed to means out of three terrestrial months. 3) IS is also a fascinating facility of cooperation for amateurs and professionals around the world. The intention is to realize a Sun spectators' network in all continents. 4) Facing all the giant scientific investigations - earth-bound as weIl as operating in space - we must be aware of ISP not being of professional but amateur character. Nevertheless ISP is of serious and severe purpose. Any experienced Sun spectators are welcome to join the international IS-Team. Please contact me if you would like to receive additional information.
