Summary

The activity of the ionosphere was high. Due to the TX problem, the experiment was stopped from 1756 to 1924 UT. After the TX break, the experiment went well. But the weather was not good.

 

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.
