    On 2 April 2012 (around 19h42.5m UT), I photographed Sar Lupe 1, 2006-60A, passing by Gamma and Eta Leonis  on 3 consecutive photos. I immediated noticed the satellite was passing significantly earlier than according to the Heavens Above prediction. Such an event is very uncommon in my experience, concerning a satellite like this.
    By analyzing my pics, and checking the times, the discrepancy turned out to be of the order of 17 seconds, compared to Calsky and Heavens-Above that give the same data.
