Hi,
I’m regular follower of NH and I’m also interested in the 2nd leg of the mission, i.e the 2016+ KBOs encounters. Does anyone know when operations about this leg (starting with searching objects of interest with HST or some other earth-based means, I suppose) are expected to begin ? |

I can discern 8 parallel, nearly horizontal, rows of artifacts per image tile. Once you start looking for it you can see this on every image. Any idea what causes that? Maybe some side effect from the subtraction algorithm?
[Edit:] Well, I had about 30 images in a row with those parallel rows of artifacts; now I'm not seeing them any more. |

If you see them again, maybe make a screen grab and send me a copy by PM... Thanks, John |
