Images of the young star HD 283572 and its surrounding field. The large image shows optical and infrared data from the Digitized Sky Survey (DSS), and HD 283572 is the bright star near the middle of the image, highlighted by a square. The insets show Submillimeter Array (SMA) images centered on HD 283572 taken on January 14th and 17th, 2022 and March 27th, 2023. The red source in the middle panel shows the flare witnessed on January 17th. The star was not detected by the SMA on the other two days, nor in five other SMA observations not shown here. The DSS image is 20 arcminutes across (2.3 light-years at HD 283572’s distance of 400 light-years) and the SMA images are 24 arcseconds across. Credit: CfA/J. B. Lovell et al.
