Abstract: Highly extended gamma-ray emission around the Geminga pulsar was discovered
by Milagro and verified by HAWC. Despite many observations with Imaging
Atmospheric Cherenkov Telescopes (IACTs), detection of gamma-ray emission on
angular scales exceeding the IACT field-of-view has proven challenging. Recent
developments in analysis techniques have enabled the detection of significant
emission around Geminga in archival data with H.E.S.S.. In 2019, further data
on the Geminga region were obtained with an adapted observation strategy.
Following the announcement of the detection of significant TeV emission around
Geminga in archival data, in this contribution we present the detection in an
independent dataset. New analysis results will be presented, and emphasis given
to the technical challenges involved in observations of highly extended
gamma-ray emission with IACTs.
