LYA HV off / OVI voltage at 210, LYA grating position now at 128000 "permanently". Observations are aborted when UVCS transitions to SAFE mode after apparently exceeding VLD Polarizer Error limits.

We will make observations from 29 October - 12 November above the limb at PA 350 along the radial towards Ulysses. The north polar coronal hole has just formed for the new cycle and is not yet stable. We hope to observe the passage of the coronal hole boundary past the sub-Ulysses point and compare the measured properties with solar wind properties at Ulysses to establish the correlation between plasma properties in the corona and in-situ.
