Just 6 shoots (10 minutes each) of Lovejoy comet on Jan_09th_2014. Look at the tail. Do you see anyting?
Despite the short that is, the offset of the breakdown of the Ionic tail can be seen perfectly due to the rapid changes produced by the solar wind in the magnetic field of ionized particles from that tail. The solar wind is usually more or less homogeneous, but at times like that of intense variations, those spectacular bubbles and ruptures occur. Thanks to Jaime Izquierdo from Agrupación Astronómica de Madrid for the explanation.
