    The Southern Hemisphere  is well placed for sighting opportunities of  2003-09C - the IGS 1 H2A rocket -  through to late May:  this rocket is likely to decay in  June - well ahead of the B object,   with the times for the C object being good owing to it being winter here.   I will try and keep an eye on it though we have been having quite a few cloudy nights and mornings

    As it is getting lower and lower and nearer to uncontrolled reentry mid-2012 
    (current orbit and SatEvo suggests August reentry date), it is vital that we 
    keep good track of this satellite (03-009B). The orbit is quickly deteriorating 
    and we should strive for a near-continuous coverage to monitor the descend. This 
    could be a nice summer project for the N-hemisphere observers and provide both 
    observers and analysts with an interesting case.
