Multiple Barcelona orbs sighted in March 2008.The sightings happened on four seperate occasions, and will be described individually: 1. My wife and I were laying on a beach just outside Barcelona on a perfectly clear day. I first noticed (and then her as well) an orb which had a yellowish-red appearance high in the sky. There was no contrail. Its movements were erratic and appeared to follow and almost elliptical pattern. It grew smaller (which I took to be movement away from the observer) and then disappeared. Approx. 10 min. later, it returned to the same place of initial observation and followed the same pattern. It again vanished within ten minutes. Total time of observation approx. 30 min.2. I was alone and walking to work when I noticed the same object in the sky over the moountains directly west of Barcelona and above the Collserola Communications tower. I was unable to observe for exceedingly long because it eventually drifted behind the buildings to my west.3. Approx. two weeks after the sighting just described, I observed the same object, but this time I was able to follow it for almost 45 minutes. It behaved in much the same pattern as previously. Initially, it apeard to be roughly half-oragen and half-red. It drifted back and forth in what appeared to be arranged patterns. Eventually, its size changed. It grew smaller and the color changed to golden, and then almost white with a metallig shine. I again assumed this to be its rising higher from my observational position. It eventually disappeared high above.4. Approx 4 weeks after initial sighting on beach I was walking to the supermarket where I observed the object MUCH closer approximately 1/2 mile from my position. It was a clear day in late March. The object can only be described as a donut lying on its side, spinning much in the same way a coin would spin when rotating to rest flatly. The center was lighter colored and the "edges" darker colored; almost brown. Others around me observed this as well, though most eventually continued on with their business. I followed the object visually for approx. ten minutes. It stayed perfectly still in the sky (save its own motion). It appeared to hover for quite some time before beginning to move slowly northbound. It speed progressively increased until it had risen higher in the sky, giving it the "traditional" reddish-orange appearance and then subsequently metallic white before disappearing.During this reported time period, there were other reported sightings in Malaga (a suburb of Barcelona) as well as along a few major highways. The objects did not exhibit any common aerodynamic characteristics, jut as they did not appear to be affected by air currents. Their movement patterns ruled out any influences by upper air currents (returning to their initial positions). These sightings have yet to be explained.((NUFORC Note: Witness indicates that date of incident is approximate. PD))
