The ghosts in GTA Online are visible between 7 PM and 6 AM in-game time. Each ghost appears for a specific two-minute window during this period, and they are distributed across various locations in Los Santos. Here is a detailed breakdown of the ghost locations and their appearance times:

1. 7 PM – 8 PM: The first ghost can be found either on a grave or on the church roof at the cemetery in Pacific Bluffs.
2. 8 PM – 9 PM: The second ghost is located under the highway in Strawberry, often near a homeless shelter or on a sofa.
3. 9 PM – 10 PM: The third ghost appears either above the tribute display on the corner house or on top of the tower with a ladder in El Burro Heights.
4. 10 PM – 11 PM: The fourth ghost is on either of the two tallest parts of the bridge near the Los Santos International Airport.
5. 11 PM – 12 AM: The fifth ghost is in the front or back of the tower at Miguel Madrazo’s Mansion.
6. 1 AM – 2 AM: The sixth ghost is in Cypress Flats, either in the doorway with the Raven text above it or above the train tracks in front of the traffic lights.
7. 2 AM – 3 AM: The seventh ghost is in the front balcony of either tower of the Rockford Hills Church.
8. 4 AM – 5 AM: The eighth ghost is on either side of the Little Seoul Church tower.
9. 5 AM – 6 AM: The ninth ghost is at the top of a level on either side of the building just north of the East Vinewood Skatepark.
10. 12 AM – 1 AM (after finding the first nine ghosts): The tenth ghost, which is the Ghost of Dominic “Dom” Beasley, appears at the bottom of the Land Act Dam.

Each ghost is only visible for two minutes during its designated time slot, so you must be quick to capture them.
