Abstract
Observations at very large zenith angles (VLZA) can push the sensitivity of Imaging Atmospheric Cherenkov Telescopes (IACTs) towards higher energies. There are successful examples of VLZA observations presented by H.E.S.S., MAGIC and VERITAS. Besides covering a broader energy range, the operation of Cherenkov telescopes under VLZA increases the exposure for transient events observations. The updated scientific strategy of H.E.S.S. has a significant focus on the detection of transient phenomena, which makes the development of the VLZA technique of crucial importance for future observations. We present a detection of the low-altitude source HESS J2019+368 using VLZA-only operation and discuss the capabilities and limitations of the H.E.S.S. instrument for this type of observations.
