Ellerman bombs and UV bursts; temporal and spatial correspondence

The emergence of magnetic flux through the photosphere and into the outer solar atmosphere produces, amongst many other dynamical phenomena, the appearance of Ellerman bombs in the photosphere. Ellerman bombs are observed in the wings of H$\alpha$ and are highly likely to be due to reconnection in the photosphere, below the chromospheric canopy. But signs of the reconnection process are also observed in several other spectral lines, typical of the chromosphere or the transition region. An example are the UV bursts observed in the transition region lines of \ion{Si}{IV} and the upper chromospheric lines of \ion{Mg}{II}. At the same time, UV burst are seldom seen in lines typical of hotter plasma such as Fe XII 195 observed with Hinode/EIS and SDO/AIA. In this work we analyze high cadence coordinated observations between the Swedish 1-m Solar Telescope (SST) and the IRIS and SDO spacecraft in order to study the possible relationship between reconnection events at different layers in the atmosphere, and in particular, the timing history between them. High cadence, very high resolution H$\alpha$ images from the SST provide us with the positions, timings and trajectories of Ellerman bombs in an emerging flux region. Simultaneous, co-aligned IRIS slit-jaw images at 1330 (C~{\sc ii}, transition region), 1400 (\ion{Si}{IV}, transition region) and 2796 (\ion{Mg}{II} k, core, upper chromosphere) $\AA$, as well as spectroscopy in the far and near ultraviolet from the fast spectrograph raster, allow us to study the possible chromospheric/transition region counterparts of those photospheric Ellerman bombs. Our main goal is to study whether there is a temporal and spatial relationship between the appearance of an Ellerman bomb and the appearance of a UV burst and the connection of these dynamical phenomena to the appearance of surges in the chromosphere.
