  This contribution presents the results of workshop 8 (supernovae) held during
the IAU Symposium 339 "Southern Horizons in Time-Domain Astronomy" at
Stellenbosch University, South Africa. Workshop 8 covered a cornucopia of
topics with each one having a short presentation by a pre-determined
participant followed by a round table discussion. During the first of two
sessions, G. Hosseinzadeh and H. Kuncarayakti presented results of their recent
works on interacting supernovae. This includes both the intriguing Type Ibn
supernova subclass, as well as SN 2017dio, which appears to be the first Type
Ic supernova to exhibit signatures of hydrogen-rich circumstellar interaction
at all phases. During the second session, M. Sullivan provided an excellent
summary related to the future of transient science in the era of Big Data, and
the participants discussed strategies to determine which targets and fields
should be selected for spectroscopic followup. Workshop 8 concluded with a
rather heated discussion regarding the need for the IAU supernova working group
to consider to modify the current criteria for a confirmed supernova to receive
an official IAU designation.
