Key Details

High-resolution magnetograms essential to see small emerging bipoles

Observed dark bubble between bipole footpoints showing plasma cooling

Ellerman bomb formed from reconnection 7 minutes after bubble

UV burst followed, with plasma heated over 1 million K

Associated chromospheric surge ejection observed

Small-scale magnetic flux emergence leads to solar atmospheric events

Using coordinated observations from ground and space telescopes, this paper analyzes the magnetic origin of small energetic events in the solar atmosphere. High-resolution magnetograms revealed an emerging magnetic bipole that was invisible in lower resolution images. This led to a series of atmospheric events: a dark bubble indicating plasma cooling, an Ellerman bomb from magnetic reconnection, a UV burst with million-degree plasma, and a chromospheric surge plasma ejection.
