I believe that it was a fuel dump.

At my location there was a moderate haze in the east and NE.  I observed absolutely nothing during the powered part of the ascent.  

I acquired the sunlit rocket at 01:50:58 UTC, 4 May. About 2 seconds later it
 passed about .1 deg over one of the brighter stars of Hercules (probably delta,
maybe epsilon in the ENE elevation about 25 deg). At about 01:51:30 I noticed 
that it brightened and there was a bright haze surrounding it - which illuminated 
the haze in the atmosphere.  The haze (from the fuel dump) was noticeable for 
about a minute. 

I could not resolve the SPOT 5 payload.   With clear, dark skies that may have 
been possible.  It disappeared from view at 01:57:46 UTC.
