Summary

The activity of the ionosphere was very low until ~20 UT. Starting at ~20 UT, the ionospheric activity became high and lasted until the experiment. Sky was also bad until ~20 UT, but it was partly clear sky later on.

 

Descriptions of SPs

 

sp_ni_oh

We run the UHF radar with CP1/arc1 mode together with NIPR OH spectrometer and other optical instruments. The target is to investigate the influence of the particle precipitation in the upper mesosphere.@ Clear sky and high activity are desired.
