I think it is important to recall these prayers throughout all of the traditional Octave of the Ascension. As I posted about previously, the Ascension was observed as an Octave up until 1954. These prayers would have been said on both the Ascension of the Lord as well as on the Octave Day of the Ascension.

INTROIT Acts 1:11
Men of Galilee, why do you stand looking up to heaven? Alleluia! He shall come in the same way as you have seen him going up to heaven, alleluia, alleluia, alleluia! Ps. 46:2. O, clap your hands, all you nations; shout to God with the voice of exultation. V. Glory be . . .
O Almighty God, we firmly believe that Your only-begotten Son, our Redeemer, ascended this day into heaven. May our minds dwell always on this heavenly home. Through Our Lord . . .
In the former treatise I made, O Theophilus, of all things which Jesus began to do and to teach, Until the day on which, giving commandments by the Holy Ghost to the apostles whom he had chosen, he was taken up. To whom also he shewed himself alive after his passion, by many proofs, for forty days appearing to them, and speaking of the kingdom of God. And eating together with them, he commanded them, that they should not depart from Jerusalem, but should wait for the promise of the Father, "which you have heard"(saith he) "by my mouth. For John indeed baptized with water: but you shall be baptized with the Holy Ghost, not many days hence."
They therefore who were come together, asked him, saying: "Lord, wilt thou at this time restore again the kingdom of Israel?" But he said to them: "It is not for you to know the time or moments, which the Father hath put in his own power: But you shall receive the power of the Holy Ghost coming upon you, and you shall be witnesses unto me in Jerusalem, and in all Judea, and Samaria, and even to the uttermost part of the earth." And when he had said these things, while they looked on, he was raised up: and a cloud received him out of their sight. And while they were beholding him going up to heaven, behold two men stood by them in white garments. Who also said: "Ye men of Galilee, why stand you looking up to heaven? This Jesus who is taken up from you into heaven, shall so come as you have seen him going into heaven."
Alleluia, alleluia! Ps. 46:6
God ascends His throne amid shouts of joy, the Lord is taken up with the sound of trumpets. Alleluia!
V. Ps. 67:18-19. The Lord is in Sinai, in the holy place; ascending on high, He has led captivity captive. Alleluia!
At that time, Jesus appeared to the eleven as they were at table: and he upbraided them with their incredulity and hardness of heart, because they did not believe them who had seen him after he was risen again. And he said to them: "Go ye into the whole world and preach the gospel to every creature. He that believeth and is baptized shall be saved: but he that believeth not shall he condemned. And these signs shall follow them that believe: In my name they shall cast out devils. They shall speak with new tongues. They shall take up serpents: and if they shall drink any deadly thing, it shall not hurt them. They shall lay their hand upon the sick: and they shall recover."
And the Lord Jesus, after he had spoken to them, was taken up into heaven and sitteth on the right hand of God. But they going forth preached every where: the Lord working withal, and confirming the word with signs that followed.
After the Gospel is read, the Pascal Candle is extinguished.
God ascends His throne amid shouts of joy, the Lord is taken up with the sound of trumpets, alleluia!
