Variable Stars South Symposium

Thu, 09/22/2022 - 00:59

Variable Stars South is holding a symposium over three sessions via ZOOM. The first session was run last weekend with four excellent presentations, but we realised belatedly that there may be many more people around the world interested in participating.

The second session will be this coming weekend and the third on the following weekend. AAVSO members are invited to join these meetings. There is no fee, however we require people to register in advance for each session via the following links:

Session 2:

Session 3:

A day or so prior to each session a link to the ZOOM meeting will be emailed to registered participants.

Arne Henden “Twenty years of V838 Mon”
