    Not my first observations, but the first ones I'm going to post.   My
    feeling is that I am overestimating errors, but better that than the
    other way.   I haven't cc'd these to anyone; not sure who wants them.
    Do I need to cc them? How do I know?  Check the archives?
    
    Two sets of binocular observations:
    
    USA 81, nice skies 5.5 lim mag(unaided), lots of points.  First point is
    more uncertain than others.  USA 81 brightened substantially in the
    eastern sky.  Very nice to watch passing through Delphinus, which quite
    nicely defined the brightest magnitudes observed.

    USA 144, skies a little more hazy later but not bad.  USA 144 brightened
    and dimmed twice in the 5 minutes of observation and ended up at the
    last point dimming to below mag 8.  The last point is therefore in more
    error as I extrapolated immediately before taking it.

    Telescopic observation:  Unknown 99097/90 907:  was watching for this
    one and the only candidate appeared 3 minutes early, but going in the
    right direction and flashing slowly from invisibility (less than mag13)
    to mag 8 or so.  No other candidates in this time frame according to
    findsat/alldat.tle.  A single point:

    Hope I haven't made any big mistakes.  Please advise.
    
    Best,
