mostly in goodish seeing targeting a CM transit of the 2010 GWS AV. The North Polar vortex is well resolved as are the vertices of the polar hexagon. I measure the AV to be at approx Lat+42.8 L3 136.2 which is in good agreement with my ephemeris. I also note a bright spot midway between the edge of the hexagon and the Southern edge of the NPR which is best seen in the IR animation. For this apparition I now have 27 data points from March 26th through November 26th for the long term drift chart which I keep for the AV, I also included 3 data points from Chris Go’s data and 1 from HST data.
