Trainers, the Safari Zone Yokosuka is now underway, taking place in Kanagawa Prefecture, Japan, from August 29th to September 2nd JST. Yokosuka SF is the final event in the Pokemon GO summer event series, and also the final event we need to complete to unlock the fabled Ultra Bonus.
The event features a Yokosuka only special research quest line, unique Pokemon spawns, Tropius and more. Couple of Gaming summarized the entire event in one beautiful info graphic:

Update: Niantic Support has confirmed that Wingull will appear more frequently only on September 1 / 2.
Hi Annie, great question. Wingull will appear more frequently worldwide, including its Shiny form, on September 1 and 2, alongside Professor Willow’s Global Challenge. ^KM

Moltres raid day unlock
Safari Zone Dortmund unlocked Articuno raid day (Last Minute Guide to Articuno Raid Day: Leeroy Jenkins!) and GO Fest unlocked Zapdos raid day (Zapdos Day Guide: Lightning Fast Lazy Mode Edition), so it’s safe to assume that Yokosuka will unlock Moltres day and, as is tradition, a shiny Moltres!
