I am not sure it will be Betelgeuse that causes the Great Solar Flash, according to many accounts in that community who have been waiting for THE EVENT (Solar Flash) for a very long time, even before Q etc. came around for us to notice. It was mentioned couple of times that a great energy wave is on it's way and that we will pass through it. Some call it the Galactic Plane, others call it the Photon Belt, but ALL speak about the same thing. THINK WAVES as per Q.

Also POTUS mentioned something rather interesting. Someday it all will just suddenly change, it will be like a "bright burst of light" Solar Flash? POTUS also made very daring pointers towards the sun when he looked at the Eclipse! (Sungazing) Some people mentioned the SUN will charge up during these months and the Spiritual State of people will determine the strength of the Flashes! All the sudden Flares etc? All part of it. Many feel those now, headaches, dizziness, body weird feelings of buzzing and vibrations.
