SOHO Spacecraft also rolled 180 Degrees. Instrument rolled to East, MOM to 1.5 / 1.3 Ro, OVI Slit set to 100 um, detector high voltage ramped down and turned off. Spacecraft Roll to 180 Degrees begun at approximately 19:11 UT, and completed at 19:37 UT.

Goal is to measure the properties of a polar coronal hole. In particular we are interested in the coronal conditions (intensities and line widths for HI Ly-alpha and OVI 1032/1037) as a function of height and latitude. We will compare these properties with the ones found in non-polar coronal holes. Roll positions are VL-corrected for PA=335 degrees.
