No, that strange device on top of the Student Center is not to communicate with aliens. Texas Christian University has installed a lightning prediction system manufactured by Thorguard, Inc. This system is designed  to predict a lightning strike within a defined geographical region.  Using sensors connected to a computer, this system is able to measure and analyze the electrostatic field in the atmosphere. It is in this field that lightning originates. Once pre-established detection limits are reached, the system activates a series of horns and strobe lights to warn those working outside to seek shelter. Since this system is automated it can provide warning even when there appears to be no evidence of lightning.  

Six sets of warning horns and strobes have been installed around the TCU campus. They are located at the Soccer field, Daniel-Meyer Coliseum, Brown-Lupton Student Center, Annie Richardson Bass Building, the Recreational Center and Liebrock Village.

When the conditions for a lightning strike exist, the system will give a 15-second blast on the horn cluster. At the same time, a yellow strobe will activate and stay on until the danger has passed or at least 10 minutes after the last detection of lightning. Once the potential for a lightning strike has passed, the system will activate the horns for an all-clear signal  -- three short blasts -- and the strobe light will go off. Because most outside activities close down by midnight, the lightning prediction is shut down between 12:00 am and 6:00 am. 

In many cases, weather systems bring with them high winds, tornados, and hail. By design, the Thor Guard system will likely activate as bad weather approaches the campus. While this system may provide some warning to these different types of weather phenomena, it does so only because lightning may accompany the storm. The warning of storms having the possibility of large hail and tornados still comes from monitoring local weather stations and the weather alert system provided by the City of Fort Worth. The weather alert siren covering the TCU campus is located at the baseball field.

Should you hear the Thorguard Lightning Prediction System activate, then you should go inside a nearby building. Do not seek shelter under towers, trees or other tall objects that could attract a lightning strike. Motor vehicles can provide shelter, but once inside do not touch any metal that could be part of the vehicle frame. If you are working with an outdoor group, cease operations and guide your participants inside.
