The IRSOL data archive includes now a new entry: the Atlas of the Third Solar Spectrum and its Center to Limb Variation.
The spectroscopic data were obtained from an observing project at the IRSOL Gregory-Coudé telescope that lasted few years. The involved authors were M. Setzer, R. Ramelli, M. Engelhard, M.Bianda, F. Paglia, J.O. Stenflo, G. Küveler and R. Plewe.
The atlas of the Third Solar Spectrum (SS3) represents the ratio between the intensity spectrum at different distances from the solar limb and the intensity spectrum at disk center (µ = 1.0), both in units of the intensity of the local continuum level. The observing positions of the measurements cover 9 different µ values along the solar axis ranging from 0.1 to 0.9 in step of 0.1, where µ=cosθ is the cosinus of the heliocentric angle θ. The current version of the atlas covers the wavelength range from 4384Å to 6610Å.

IRSOL is the local organizer of the SCOSTEP workshop that will be held on 10-11 October 2017.
The Scientific Committee on Solar Terrestrial Physics (SCOSTEP) is an international organization with the goal of strengthening and promoting international solar-terrestrial physics research. As of 2016 Switzerland is a member of SCOSTEP and a National Committee has been established with the goal of promoting and representing the solar-terrestrial community within Switzerland and internationally.
SCOPE OF THE WORKSHOP
The workshop aims at bringing together Swiss scientists with an interest in solar-terrestrial science. It encourages a lively exchange between scientists from all fields within solar-terrestrial physics to identify synergies, foster collaborations, and strengthen the community.
THE FORMAT OF THE MEETING
The workshop will consist of two invited talks plus contributed presentations (oral or poster). It will cover the following topics:
- Fundamental solar physics
- Solar variability in the past and future
- Sun-Earth relations in proxies, observations, and model simulations
- Future (space) missions/observations
- Astrid Veronig, University of Graz
- Hauke Schmidt, Max Plank Institute for Meteorology

The Swiss Astronomer Rudolf Wolf was born on 7 July 1816.He was the first director of the Swiss Federal Observatory in Zurich and he is well known for his studies about the solar cycle and the sunspot observations.
