 ToO program on Sakurai, a born-again giant, currently in its 2nd AGB 
phase after having experienced a final He-shell flash while descending 
the WD cooling track. Aim of the program is to monitor this variable 
target 3 times during P69 (once every couple of months, depending on 
when it is brighter than V=16). During each of these 3 times, 3 OBs (1h 
each) should be observed during the same night (cf README file for more 
details). PI and Co-I (Kerber) will activate each single part.
