    Having gone through the images from early this morning ...there are 50 or so 
    useable frames ........, there's an interesting sequence of  four grabs , 
    all taken within a second at about 79 deg elevation.
    http://mysite.wanadoo-members.co.uk/satcom_transits/lacsm.gif
    
    I'll load the full animation later.
    
    What I find interesting about this sequence is that it is similar to Phil 
    Masding's taken this time last year.
    
    About 5-10 seconds after these frames were grabbed , Lacrosse 5 cloaked up 
    .....well before it should have gone into shadow.
    So , how could something so bright disappear in such a short time.
    It wasn't tumbling or rotating.The only other thing I noticed is that rather 
    than flaring , it seemed to "glint"
    
    Is the large bright centre the antenna and the small "tails" the solar 
    panels ?
