In the back of the Chumash Shai LeMorah, a list and hierarchy of the the people who are obligated to receive an Aliyah to the Torah. He adds parenthetically as follows:
It is written in the Sefer Avodat Hakodesh of the Chida Z"l that there is a custom in Eretz Yisroel that someone whose wife enters her 9th month of pregnancy should be careful to do the ...
It depends on the synagogue, and depends what you're being asked to do. I'll assume the synagogue is Ashkenazic.
If you're being asked to open the aron (cabinet holding the Torah scrolls) for a particular prayer, but the scrolls are not to be removed, then the first step is to approach the aron at the appropriate time. (Actually, as mentioned in the other ...
The Ba'er Heiteiv and the Mishnah Brurah (Orach Chayim 104, 2 in the BH, 9 in the MB) say
העולם חושבים זה קצת למצוה
that the people consider opening the ark to be somewhat of a mitzvah.
In context, they say that if one is finished with Shmone Esrei and has said the pasuk "Yihyu l'ratzon imrei fi", but has not yet stepped out of position at Oseh Shalom, he ...
From an article "Pesicha During Pregnancy", by Rabbi Yossi Braun:
The Birchas Ephraim 60 (This is a pamphlet that is printed as an
addendum to Pischei Sh'earim, Talmudic novellae by Rabbi Yisachar of
Tchenstechow - Bilgurei 5660). says as follows: "My children, do not
forget to introduce the tradition from our master, the Rashba, in
whose name I ...
The Zohar (which is the source for saying this in the first place) states that the prayer should be said "כד מפקין ס"ת בצבורא למקרא ביה", when the Torah scroll is removed in the minyan to be read. Of course, this is still relatively ambiguous.
The Siddur Maharsha"s (R. Shabtai Sofer), one of the first mainstream siddurim to include this prayer, says to say ...
Open the ark after kaddish but wait for the chazzan to walk towards you before you take out the Torah. When he does, take out the Torah and hand it to him. He will recite the pesukim(according to Ashkenazi custom); after which you should close the ark.
He can continue walking if you don't close the aron if the minhag is such or wishes to do so.
It is ...
Since I and two rabbanim I asked didn't find classical sources addressing this case, I think we have to break down your question into three
Are you forbidden from opening the ark?
Do you have to open the ark?
Should you open the ark?
You are clearly not forbidden from opening the ark. A yachid that wants to pray in a shul in front of an open ark can do so. ...
I have seen the ark kept open until the singing is concluded.
The Koren Siddur says that the ark should be closed after the u'vnucho yomar verses are concluded. It shouldn't really make a difference whether they are being said quickly or drawn out.
My sense is it's just a matter of respect for the visibility of the open Aron; if all the congregants are looking at the Torah scrolls, you don't want to appear like you're hogging the attention and blocking their view.
If for whatever reason you need to be on the other side, I'd say just cross over as quickly and as unobtrusively as possible.
That's just ...
Rabbi Cohen at Dose of Halacha answers this:
To emphasize the holiness of anim zemiros, ascribed to R’ Yehuda Hachassid, we open the aron hakodesh while singing it. The Bach (OC 132) mentions the minhag to sing it daily, though most shuls sing it every Shabbos while the Vilna Gaon held that it should only be sung on Yom Tov (See Nesiv Bina 2 p260).
Before I made Aliyah, at Birmingham Central Synagogue (England) the custom was for a child to open the ark for An'im Zemirot. I don't know whether this is still practiced. It therefore appears to be permitted.
