Although the majority of hot magnetic stars have extremely stable, $\sim$kGstrength surface magnetic fields with simple topologies, a subset undergosmall-scale explosions due to centrifugal breakout (CBO). The resultingsmall-scale flares are typically below the sensitivity of currentmagentospheric diagnostics and do not generate detectable transient signatures.However, a recently reported radio flare from the hot magnetic star CU Virsuggests that some of the most energetic events do reach detectable levels.Motivated by this, we searched for transient radio sources in the first twoepochs of the VLITE Commensal Sky Survey (VCSS) at the position of 761 hotmagnetic stars. We report three detections. A false association analysis showsa less than 1% probability that the sources are imaging artifacts. We thenexamine the stellar parameters of the three stars to understand if they arelikely to produce flares. We conclude that while at this stage we cannot make adefinitive association of the detections with the stars, the current data areconsistent with the hypothesis that the flares originate in the stellarmagnetospheres.
