Flag Land Base Day (2019)

Three days ago, on December 7, 2019, Flag Land Base Day was celebrated (Confusingly, some websites list December 6 instead).
This date on the Scientology calendar commemorates the opening of the Flag Land Base in Clearwater, Florida in 1975.
We have been looking for any online reports about the festivities, but there are no mentions.
The rather small number of Scientology websites seem to be saying little. The usual handful of blog posts about some small demonstrations and indoctrination gatherings. To be fair, these events are presented as vitally profound and world-changing.
However, we should expect a bigger event next year, for the Flag Land Base's 45th anniversary.
