To all who say it is impossible.. I am living in a gulf coast city in Mexico. Old infrastructure. Last week we had big windstorm. Trees and utility lines down all over city and outlying area.. Concrete utility pole in median across from my house broke in half when wood pole 1/2 block away shattered. In two days , new poles installed and services restored on my street. They used the same transformer from old pole. Three nights ago was having my nightly Marlboro on my balcony. Saw an orange glow on side of power transformer near the very top. Thought maybe was moonlight at first, then realized it was completely overcast.Glowing area was growing on surface of transformer can. Grew to almost football size for maybe 40 seconds and then gradually decreased to not glowing. At brightest it went from glowing orange to yellow. This happened 3 more times in the next couple of minutes. Then nothing. I was worried about fire or explosion. Was almost 2 AM and no emergency phone listing for power company. I went to State Police and reported. They did not care , so I went to fire station and they took my report. Nobody from power company arrived to inspect , so I spent almost half of yesterday at local power company reporting. Speaking to my neighbors, I think they thought I was loco Gringo. Last night just as was almost dark the transformer blew spectacularly. I wonder if the neighbor who had his 4 month old SUV parked under the pole still thinks I was exaggerating.? His car is toast. Oddly, during daylight the paint on the exterior of the transformer can did not appear to be at all scorched from heat. This makes no sense to me. No heat marking. I have some knowledge of the internal workings of these type of transformers. I am positive what I viewed from about 70 feet away. This pole is in the street median directly across from my balcony where I was standing while observing occurrence. I do not drink or do drugs. Have never seen a U.F.O. The only time I saw Elvis was at an Elvis concert.
