    No flares at all noticed on the recent passes, apart from the "unflare" 
    reported the other day when it DIPPED in mag just before culmination.
    
    Considering how bright it was at steady mags a flare would be spectacular! 
    Clouded out for this morning's overhead pass.
    
    Would be useful to have some more observers down here so we could compare 
    notes (and hopefully get observations when I am clouded out) but 
    unfortunately the early hours have made this difficult, once we go to 
    evening passes there is more chance of this occurring and we also have some 
    good post separation opportunities.
