The article quotes Jason Goldthorpe (the viewer) stating:
"They always appear at teatime and just on one day, either at the beginning or end of the month."
Based on that quote & the video, I have to think someone's releasing balloons or lanterns late in the day / early in the evening.
The objects seem a little bright for lanterns unless the sky is overexposed & lightened, thereby making the objects appear brighter in the picture &
If they are reflective balloons as per Phage's comments, the colour & the brightness could be caused by a low angle (i.e. setting) sun.
