You can dial up the date on Sky Safari. That's how I came across this event while looking up possible dates for outreach/sidewalk astronomy nights with the planets and Moon on view. Great tool Sky Safari. What I'm not sure about is if this event is visible everywhere around the world - of course take your own local sunset time into account. The time I've posted is for Sydney.
Might look into organizing a special outreach/sidewalk astronomy event for this occasion. There's a few parks in Sydney's east that could do that have gorgeous east-west views. Anyone like to join me?
Mind you, I've had the Spooks called on me at one of these parks once before... They'll totally flip with this one!
