Weather conditions at time of sighting: Temperature 79 F, Barometric Pressure 29.94 in, Visibility 10 miles, Clouds Partly Cloudy, Dew Point75 F, Humidity79 %,Wind WSW 10 mph, Cloud Cover 45%, Cloud Ceiling 30000 ft.

The object continues to hover at this hour. It is approximately 40 degrees above the horizon emitting a bright white light. The object periodically rotates and several portals can be seen along its outer perimeter. The object is hovering at about 20000 feet, approximately 15 NM southwest of my position bearing 238 degrees relative.
Neither Broward or Palm Beach Counties had their aviation units in the air. However a single airplane departed KBCT at about 2035 hrs. The airplane was climbing out on a northwest heading after departing the traffic pattern. The KBCT tower was closed and could not contact them to inquire if they had radar paint on this object, however this object was within the boundaries of the Miami TCA. I'm sure I am not the only observer to report this sighting.
ADDENDUM FROM SOURCE OF ORIGINAL REPORT:
LARGE GLOWING OBJECT IN SKY
I wish to amend the report I submitted last evening.  When the craft rotated right to left on its axis I could see what appeared to be rectangular shaped observation windows  that were located aft of the craft's leading edge.  My distance to this craft was too far to hear any sounds.  I speculate that it must have been quiet.  Assuming for a moment these are visitors from another part of our galaxy I strenuously recommend that we continue to treat them as friendlies unless they demonstrate aggression.  God help us if this craft is really on a reconnaissance mission; part of a vanguard of an invading army from another planet. Editor it would be a good idea if you contacted the Towers at FLL and MIA.  They may have recorded a radar paint of that craft.
