Frank had it scheduled for the 31st, the last Sunday of the month, which has been his longstanding schedule practice. Someone at InfoAge assumed that it was the third Sunday of the month (which the last Sunday of the month often is) and put it on the InfoAge calendar that way AND advertised in the local media using that date. Because of that, Frank had to change the presentation date to match the advertising. For future reference (with the exception of this month) the NASA lectures are always scheduled on the last Sunday of every month except December.

It's usually on the last Sunday of each month, January through November, but this month (March) it's on the 24th due to a scheduling error. If you see it advertised for the 31st, that's the wrong date. More info: https://isec.space/ Someone else was asking about the recent 'big name' NASA presentation. If you missed it, you can catch Kim Arcand's talk about her spectacular 2D and 3D visualizations of space on InfoAge's YouTube channel: https://youtu.be/a_xrTvBk9E0 -- Dave Sica -- ======================================================= Jeff Brace =======================================================
