WZ Sge: second superoutburst finally? or another rebrightening? The most recent observations indicate WZ Sge almost retains its maxium magnitude at its fifth rebrightening (the fading from the fifth rebrightening seems to have been quite slow). Or the star may have undergone a quick rebrightening during a very brief gap of observation (?). This may be an indication of the start of the long-awaited second superoutburst, or something unexpected/unexperienced. Please keep the vigil as much as you can!
