It’s #SunDay#! Here’s your space weather report for the week of May 15 - 21: • 4 M-class flares • 3 C-class flares • 35 coronal mass ejections • 1 geomagnetic storm This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity. It was a fairly calm week on the Sun. A coronal mass ejection last week reached Earth on May 15, triggering a minor geomagnetic storm and leading to aurora sightings across the northern U.S. On May 20, SDO's Helioseismic and Magnetic Imager (HMI) paused normal science operations for a series of routine calibration maneuvers — measurements that keep the instrument's magnetic field and Doppler velocity data scientifically accurate. You can see these maneuvers starting at about 2:29 in the video. Learn more about space weather:

With the rapid development of embodied artificial intelligence (AI), a new profession - trainers of embodied AI - has emerged, which comprise roles such as data collectors and data annotators. Jinan and Qingdao in Shandong Province have established robot data collection and training centers tailored to various scenarios. Equipped with simulated workshops replicating real-world environments such as automotive manufacturing, 3-C factories, logistics, retailing, and household care-giving, these centers allow trainers to guide robots one on one through tasks like grasping, identifying, walking, and delivering.
