Palpatine's public appearances outside of the Lords of the Sith novel or the Imperial Senate scene in the Bad Batch, after the Declaration of the New Order, were limited and typically tied to major events like Death Star unveilings or significant Imperial gatherings.

Was there ever a Death Star unveiling? I thought it was a secret until after it was destroyed

Ye, srry ur right it was unveiled when Alderaan was destroyed

Right, and then it got destroyed the next day. Are there any examples of imperial events that he was present for?

1. Declaration of the New Order: Palpatine declared the formation of the Galactic Empire and the ushering in of a new era in “Star Wars: Episode III - Revenge of the Sith.”

2. Death Star Unveiling: While not a public event, Palpatine was present for the reveal of the first Death Star in “Star Wars: Episode IV - A New Hope.”

3. Executor Star Dreadnought Launch: Palpatine oversaw the launch of his personal flagship, the Executor, a Super Star Destroyer, in “Star Wars: Episode V - The Empire Strikes Back.”

4. Imperial Senate Address: In “Star Wars: Episode VI - Return of the Jedi,” Palpatine addressed the Imperial Senate on the new Death Star and the imminent crushing of the Rebel Alliance.
