Videos capturing these strange, rapid light changes in clouds have popped up a lot in recent years, and they defied immediate explanation. But after what NASA rather charmingly calls some "inspection and contemplation", we now have a rather nifty explanation for just what's going on here:
In sum, this hypothesis holds that a lightning discharge in a thundercloud can temporarily change the electric field above the cloud where charged ice crystals were reflecting sunlight. The new electric field quickly re-orients the geometric crystals to a new orientation that reflects sunlight differently. In other words, a lightning discharge can cause a sundog to jump. Soon, the old electric field may be restored, causing the ice crystals to return to their original orientation.













Comment: From "A brief guide to Corrupted Science":
Whenever NASA (or other corrupted institution) says that they have done some "inspection and contemplation", what it really means, that they took some time to fabricate data or invent a ridiculous and fraudulent explanation in order to conceal the truth.
