@jhakhohbhy No, there were no sounds of thunder that night. The sky & weather were clear. You could visibly see the horizon. What made the pulsating lights seem unusual other than their movements was the fact that they appeared over a large background of dark clouds with numerous flashes of amber lightning concentrated within the clouds. Only the brightest lightning flashes were captured on the videos. The whole appearance which lasted about 40-45 minutes had occurred in total silence.
