    Seems unlikely, unless it has a very high areal density. Will be able to
    estimate once elsets with reliable decay rates appear.

    The first TLE of 10026A / 36595 has appeared on Space Track. Orbit is 34.5
    deg, 239 km X 280 km.
    
    A quick check of current visibility north of the equator, reveals the tail
    end of evening visibility at latitudes south of about 30 N; no visibility
    further north. Morning window opens in a couple of weeks. South of the
    equator, around 35 S, has tail end (several days) of morning visibility.
