ISCS Working Group1 Activities
Abstract
International Solar Cycle Study,Working Group 1, "Solar Energy Flux Variations: From the Interior to the Outer Atmosphere" is concerned about measuring and analyzing solar irradiance variations and their underlying physical mechanisms. In this paper we report the latest results on WG 1 activities, i.e., the variations of solar total irradiance and spectral irradiance from EUV to infrared. The most interesting result is that while solar cycle 23 was relatively weak compared to the previous two cycles as far as sunspots are concerned, both total and UV irradiances reached about the same maximum level than during cycle 22. The implications of this observation will be discussed. A summary of future irradiance measurements, plans, perspectives and organization efforts will also be presented.
