evidence: The High-frequency Active Auroral Research Program (HAARP) is a research facility that uses a high-power, high-frequency transmitter to study the physical properties and behavior of the highest point of the atmosphere, the ionosphere. Radio transmissions from HAARP only cause small effects in the ionosphere that last for a brief span of a few seconds. HAARP is incapable of causing the magnitude of aurora effects witnessed in May 2024; evidence shows these effects were caused by mass ejections of magnetized plasma from the Sun.
