What is the pesicha of Omnon Ken on Kol Nidre night? When does it occur, and on what page of the Artscrol Siddur can it be found?
1 Answer
After the Amida on Kol Nidrei night, there are a few paragraphs of Selichot that are said.
The 3rd or 4th starts with the words Omnon Ken - and the Aaron HaKodesh is opened while saying it - hence "pesicha of Omnon Ken".
It's on page 175 of the Interlinear ArtScroll Yom Kippour Machzor, Ashkenaz edition.
