Summary
The sky was
clear before 22:30 UT, but it went worse: cloudy after that. The ionosphere was
active.
Descriptions
of SPs
sp_ni_mi
We will make an optical campaign using aurora cameras, proton imagers and 4-wavelength photometer with tje EISCAT UHF radar. Clear sky and higher geomagnetic activity are desired. Although we made request for 5 nights, we will run only 3 nights depending on conditions.
RIOE2006
The main goal of
the experiment is an investigation of the mechanisms of high power radio-wave
interaction with F-region ionospheric plasma. The UHF EISCAT radar will run the
tau2pl program to measure the spatial and temporal variations of the
ionospheric parameters simultaneously with multispectral optical observations
of the HF induced optical emissions by ALIS (IRF) and ASK (KTH). In particular
we are going to study: the differences in temporal behavior of the different
optical emissions as well as the electron temperature and density; the pump-power
dependences of the emission intensities. To conduct the experiment successfully
quite geophysical conditions, strong enough ionospheric F region, and clear sky
are needed. If ionospheric conditions will be insufficient (critical frequency
less than 4 MHz) or there will be strong auroral activity we will run same
observations (but the arc1 program will be used instead the tau2pl for the UHF
radar) to study the influence of the HF heating on the ionosphere-magnetosphere
interaction.
