DESCRIPTION: Ellerman bombs and UV bursts are transient brightenings that a
 re ubiquitously observed in the lower atmospheres of active and emerging f
 lux regions. While some Ellerman bombs display clear UV burst signatures\,
  not all have correlated UV signal or vice versa\, suggesting the underlyi
 ng atmospheric and magnetic properties may differ between events. As both 
 are believed to pinpoint sites of magnetic reconnection in reconfiguring f
 ields\, understanding their occurrence and detailed evolution may provide 
 helpful insights in the overall evolution of active regions. Here we prese
 nt results from observations and inversions of SST/CRISP and CHROMIS\, as 
 well as IRIS data of these transient events. At unprecedented spatial reso
 lution the CHROMIS Ca II H &amp\; K observations reveal dynamic fine struc
 ture suggesting a plasmoid-mediated reconnection process. We investigate s
 everal cases\, combining information from the Mg II h &amp\; k and Ca II 8
 542Å and H &amp\; K lines in order to infer the temperature stratificatio
 n and magnetic field configuration within which these events occur. I’ll
  address the difficulties of successfully inverting their Si IV profiles a
 nd will discuss our results in light of the current debate on the connecti
 on between UV bursts and Ellerman bombs\, their occurrence heights and in 
 particular the temperatures that they may (or may not) reach.\nSpeaker: Gr
