    An early morning session, thanks to insomnia. Nice clear sky, first night with 
    frost (-0.7 C) registered by my weather station this winter (on 25 January! This 
    is a ridiculous winter!). Nice pass of Lacrosse 3 (97-064A), two good crisp 
    trails on the images, it was bright, mag +2 similar to the Big Dipper stars. It 
    was some 0.4s late and on-track.
    
    On the first image I also captured old-timer Kosmos 624 (73-104H) as a stray. 
    The trail is faint, especially the start of it. It must have been flaring, as 
    the predicted magnitude was +7! Instead it was about +3.5 or +4.0 I estimate 
    from the image. I did not note it visually as I was following 97-064A at that time.
