The meet-up

Wave back on Nov 17.

The space agency is inviting everyone to point a light at the sky after sunset on Tuesday, Nov 17, the evening before the milestone, and flash Voyager’s call sign: V · G · R.

A phone, a flashlight, anything. Quick flash under a second, long flash about one second, a pause between letters. Repeat for about a minute.

It is a symbolic wave. Nothing will reach the probe. That is kind of the point. Details on the official event page.
