        Gidday Rainer, Yes , thanks, I note it took only approx 5 hrs to get past a mid point in C3 and be detectable. Kind regards, Alan.

            Can't see it, all I see is bright junk from the solar corona. I get
            the same point intensity values you do at the same co-orindates, but
            the values one pixel away are very similar. It looks to me like
            artifact (I've stacked, got the miniumun theough z-project,
            subtarcted, done a square root then aligned with RO1 and also used
            unaliogned images. II don't see anything that doesn't look like
            coronal chaff, but that just could be me)

            Cheers! Ian (who might just be over this cured ful!)

              Gidday Ian,
              Good to see your up and fit, I had that three day to a week flu thing
              also, could not eat for four days, walking dead syndrome...

              On the comet, don't align to close to the edge, if you have a rolling
              wheel on your mouse or key board, cycle across 024900 and 044900
              frames. Its about third up from bottom of image extreme left.

              Moves in opposite direction to solar artifacts. If you are using
              imagej to process th e0913 sequence then it is just as the lower
              section goes from dark to light as the satellite repositions(?).

              Kind regards,Alan.
