POLArisation of the thermospheric Red Line In Svalbard

This proposal is an extension of the proposal 1026. After a series of discoveries and a first wintering at Ny Alesund, it is now desirable
to perform long term measurements of the red line polarisation. Long term means at least over ½ a solar
cycle (about 6 years) from the same observation position. The goal is to link
the polarisation to the solar activity to make it a new space weather window on
our space environment. We already have a few months from Hornsund, and a few
months from Ny Alesund. We propose here to complete this series of observations
for the next 4 winters at Ny Alesund.
