    Same passes, about 120km to the west.
    The Shenzhou 3 Rocket is in a slow roll. I had a rough flash times of about 11-16 seconds.  The first cycle (beginning at 0:07:48.45 UTC, 30 March) consisted of 7.25 of 0 mag followed by 5.75 of inv.  The next cycle was 14.25 at a brightness peaking at -1 mag followed by 2.88 secs inv.  The next 3 cycles were difficult to determine because it did not go completely inv.  They were 7.83, 10.93 and 15.3 secs respectively.  Although there was a fair amount of ambient light it was clear to me that this object was tumbling.  The pass itself was NW -> E  -  max elevation 55 deg in the NNE.
    Shenzhou 3 followed with a nice W->E pass that was nearly directly overhead beginning at 0:29 UTC, 30 March.  When it was low in the west  near Aries  it was probably no more than +6.0 mag.   It was not visible at 1x until it reached an elevation of about 40 deg in the west.  As it passes directly overhead it reached a maximum brightness of about 1.5 mag.   As it approached Leo, high in the east, it was clearly brighter than gamma-Leo  probably 1.7 or so.  I followed it until it entered eclipse around 00:33UTC
