NEW THIS YEAR!! For the very first time the AAVSO will be offering a full online meeting attendance option. In the past we have broadcast the Saturday morning membership meeting to our members free of charge. We will continue to do this, but we will add the option of registering for the meeting as an online attendee and virtually attending all paper sessions.

We will be using a webinar service to broadcast the meeting. Video will consist primarily of the presenter's PowerPoint presentation with occasional webcam shots. Prior to the meeting, you will receive an email containing links for each session. We will also give attendees access to recordings of each session for a limited time after the meeting.

We are happy to expand the possibilities of meeting attendance to more of our members, observers, and friends.

The Non-member rate includes AAVSO membership for the year 2015. If you are already a member, please log in to register at the member rate.
