We make the following predictions: (1) Comet 67P/Churyumov-Gerasimenko. The Secular Light Curve (SLC) of this comet exhibits a photometric anomaly in magnitude that is present in 1982, 1996, 2002 and 2009. Thus it must be real. We interpret this anomaly as a topographic feature on the surface of the nucleus that may be a field of debris, a region made only of dust or an area of solid stones but in any case it is depleted in volatiles. We predict that images taken by spacecraft Rosseta will show a region morphologically different to the rest of the nucleus, at the pole pointing to the Sun near perihelion. (2) Comet C/2012 K1 Panstarrs. This comet exhibits the same Slope Discontinuity Event (SDE)+magnitude dip after the event than 11 other comets listed in Table 1 all of which disintegrated. This group includes comet C/2012 S1 ISON. Thus it is reasonable to expect that this comet may disintegrate too. The probability of disintegration of this comet is 20%. (3) Comet C/2013 V5 Oukaimeden. This comet exhibits the same SDE+dip signature exhibited by 11 other comets in Table 1 all of which disintegrated. This group includes comet C/2012 S1 ISON. We predict that there is a 90% probability that this comet will disintegrate.
