Sometime in March, 1995, at 0630, facing west, l saw a large fireball move very fast from south to north, changing colors as it moved

At 0630 sometime in March,'95 while waiting for a bus to take me to work, I saw a fireball zooming at great speed across the sky. It changed colors as it streaked across the horizon, going from south to north, parallel to the ground but seeimg to arc downward as it disappeared over the northern horizon.  
I expected an implosion and braced myself but neither saw nor heard any evidence of ground impact. 
There was no tail, no stream, and no noise as it moved across the sky. It wasn't far away and it wasn't high above. 
And, it was large. Can't say how large. If it had been a meteor it would have made a tremendous expolsion.  Meteors do not, I believe, move parallel to the ground.
 Later, at work, I fouind out that another person, a woman, an English as a Foreign Language instructor as myself, had also seen the fireball that same morning at the same time.  In fact, she and her teenage daughter had seen it as they drove to the girl's school.
There were no reports of sightings either in the newspapers or TV news broadcasts.
Witness indicates that the date of the event is approximate.  PD
