    77 images yesterday, this time 20s exposure, 21:17 - 22:21 UTC.
    Semitransparent, horizontal cloud bands drifting by, making elevations
    below Albireo less sensitive.
    >From 21:55 they partly covered the entire FOV, 15-80%.
    Image 257 and 285 could be 98 degree orbits.
    Seven more UNID's to identify, dismiss, reduce and/or report.
    Browsing the RAW images magnified (ie 100% scale or more) could reveal
    more tracks.
    
    99285 13 599A   5919 F 20130409221325500 18 25 1853016+355261 55 S
    99285 13 599A   5919 F 20130409221345500 18 25 1921864+401917 55 S
    
    This appeared similar in brightness (for once I detected it visually
    while the camera was processing the previous image) to the bright
    object Apr 07 (597F = 99148). It seemed to be fading from about +3 (or
    brighter) when I detected it.
    
    It seems closest to Cees' 13596C object, but 15 min early, 10% slower,
    and 11' above the track of the adjusted orbit.
