     Lancashire, UK, 76mm f/16 refractor, x170, Wratten 25, and 44a 
     Moon blink filters used, Transparency 4.5/5, no wind, S=F). The 
     west flank of Maginus, and the interior, appeared to be partly 
     obscured. No other features in a similar position along the 
     terminator were obscured. No colour blink was detected with the 
     filters, though a pronounced red/white light blink was noted; the 
     device employed a N.D. x4 filter. By 21:45UT the floor was no 
     longer obscured and only Magninus G was masked in a white haze; 
     however immediately adjacent to the terminator was an ill defined 
     misty patch lying where the outer flank of maginus would have 
     been visible. The rest of the terminator was sharp. The 
     obscuration was only seen to advantage in blue and int. light, 
     and the blue/int blink was only very slight. Findlay and 
     McDonnell observed 21:30-23:00 using a 25cm refractor (Seeing II-

     After studying the whole length of this valley, the observer saw 
     a change in "albedo" and a small change in colour of the valley 
     floor near to the Plato end. This colour was not seen in a 
     yellow Wratten 15 filter but was noted in a purple Wratten 35
