The centrepiece of the Broad Street revamp has been switched back on.
The fountain was officially switched on last October but turned off again shortly after for winter.
The popular water feature was switched on again this morning, but is expected to be off during the weekend while experts continue to test the fountain.
It should be back on full-time on Monday.
With around 60 jets, the illuminated fountain will be on from 8am to 10pm, seven days a week.
While the designers have said it’s capable of limitless patterns and sequences, it has been programmed with two main modes.
For the first hour each day it will operate in what is known as relaxed mode.
Then from 9am, a 10-minute dynamic routine will be performed on the hour and half-hour until 10pm.
The start of the dynamic mode is signalled by the LED lights turning off for around two seconds.
In this mode the dancing effect of the fountain is said to be more lively, shooting to greater heights.
During the relaxed sequence the water feature will still be seen to dance.
The fountain is set to run throughout spring, summer and autumn before again being switched off for winter.
When the winds pick up, the fountain will scale itself back to reduce spray. At 15m/s the feature reduces to 75% and at 30m/s it will shut down and restart automatically once the wind speed lowers.
The feature forms part of the £3.2 million development in the area, which includes a raised grass area, trees benches and a flexible event space, which has already been used for a number of events including Celebrate Aberdeen and the Christmas Village.
Speaking ahead of last year’s switch on, Peter Dawson, director of fountain designer OCMIS, said the city of Aberdeen was one close to the company’s heart after previous projects in the region.
He said: “The fountain in Aberdeen is really good because it’s intensive and exciting.
“We were discussing the idea back in 2014 so it’s been a long time in inception.
“It has 61 jets and each nozzle can be programmed to perform a different height or sequence so the options are limitless.
“Sometimes with fountains the public can get a bit bored when the sequence is the same, it can become part of the background, but this way the council can keep it interesting.”
