Red orb lights. Pulsing,.hovering, darting

At approximately 11pm with dark, clear skies atop the Santa Cruz mountains near Loma Prieta multiple witnesses observed red round lights that shifted position from a diamond shape with 4 lights to a single red light, flashing, then steady, slowly floating up and down, then flashing red to bright white,and bright purple to red, streaking and darting rapidly, then fading and reappearing in a different spot. .A halo / haze was noticed around the activity that blurred out the stars within it, yet stars were visible everywhere else. These lights had a high bright scintillation that was different from typical aircraft nav lights also visible in distance at the same time.
