spectrally
In phantom fashion
In a manner relating to spectra—the bands of light, sound, or other radiation spread across a range: The light split spectrally through the prism.
Also in a manner relating to ghosts or phantoms: The figure moved spectrally through the fog.
Both senses share an association with things partly visible or dispersed.
