    Hi all,
    Last night at 20h22 UTC I took a series of 6-sec photos of a large field near Beta Leo, while imaging a nice pass of Breeze-M 2008-57B (obj 33437 Astra 1M Tank)
    On an unique photo I spotted also a bright flare of a very slow satellite. Using Calsky I immediately identified it as object 29670,  2006-62 A (orbiting at about altitude 19000 km). I estimated that the flare was possibly of magnitude 5-6 (since I failed to notice it visually while watching carefully the field) and certainly of less than a half second duration. The satellite remained fainter than mag 11 during all my observation because nothing else but the short flare was recorded on my photos. 
    I am used to find passes of very slow satellites (orbiting higher than 10000 km and up to 40000 km ) recorded on some of my photos (of course without counting all geostationary satellites I am currently observing), but that's the first time I happen to record a flaring so sharp and so short of one of them.
