    "body_text": "High-resolution 416-nanometer observations from the Daniel K. Inouye Solar Telescope covered 143 reconstructed frames over about 3.2 minutes. The analysis identified 201 photospheric vortex detections with a median equivalent diameter of 38.6 kilometers and median swirling period of 37.3 seconds. Virtually all were below 50 kilometers, matching a scale predicted by magnetohydrodynamic simulations but previously beyond direct observational reach, according to the authors.",
