In the parking lot of Walmart 875 Palm Bay rd happened to glance up at the evening sky and noticed an object what first appeared to be the only star in the sky but at closer look appeared to be 2 stars one under the other or possibly light emitting downward from the first object ,the object appeared stationary , i stopped a fellow patron walking by and the 2 of us sat for 30 minutes watching this thing trying to reason what it might be after 30 minutes as the sun was almost gone the object appear to go below the horizon ,I assume it was stationary and what we were seeing was the earth turning it out of our view. this was clearly not normal aircraft , we also both seemed to see little sparks of light emitting irregularly from the bottom object/beam
