Watch & hear recordings of Planetarians' Web Seminars.

Upcoming PPA events:

  • 2019 October 25, 8:30 am Pacific Time (15:30 UT) Planetarians' Web Seminar
    Topic: Showing recent satellite imagery in your dome.
    Presenter: Marc Horat, Planetarium director, Swiss Museum of Transport, Lucerne, Switzerland.
    Description: Recently, Marc gathered data and imagery from the archives of the US National Oceanic and Atmospheric Administration (NOAA) for a show with live presentation. This expanded the usual space related topics to include a focus on Earth centered topics like weather patterns, hurricanes, sea ice and climate change. Feedback from the audience has been overwhelmingly positive as they simply didn't expect a planetarium to be able to show such data, movies and images that were only available days or even minutes ago. Marc will share his knowledge, workflows and experiences for finding the data, processing it and presenting it in a planetarium.
  • Planetarians' Web Seminars (zoominars) are usually on the last Friday of the month at 3:30 pm PDT, 4:30 pm MDT, 5:30 pm CDT, 6:30 EDT. For connection URL, see the PPA Connect to Zoominars page.

The Pacific Planetarium Association would like to acknowledge the life and legacy of Dale Etheridge, founding member of the PPA, who has passed on, but remains with us in memory.

PPA is an affiliate of International Planetarium Society.
PPA is also one of the planetarium societies in the Western Alliance Conferences.
