There are many narrations in Sunni books about the Sun rising from the
west as a sign of the Day of Judgment as it is narrated in Sahih
Bukhari  (vol. 5 pg. 195 and also vol. 7 pg. 191)  and in Shahih
Muslim (vol. 1 pg. 95). The narrations says that after that incident,
the repentance will not be accepted.

In our Shia books of Hadeeth, we also have many narrations that the
rising of the Sun from the west will take place but not as s sign of
the Day of Judgment. In Kitab al-Irshad by Shaikh Mufeed (pg. 358)
narrated from Abi Hamzah al-Thimali saying : “I asked Abu Ja’far
al-Baqir (AS) : “Is the coming of Sufyani definite?” He (AS) said
“Yes. And the huge sound from the sky and the rising of the Sun from
the west and the dispute between Bani Al Abbas and the killing of
al-Nafs al-Zakiyah and the coming back of Imam al-Mahdi (ATFS) are all
definite”.”

Wassalam.
