3 lights hovering over Riverside County. 2 eye witnesses.

47 year old male, born and raised in general area.  Former army reservist, former police officer and correctional officer.  My house is in an area that is elevated compared to the rest of the city, and my back yard can oversee the scope or span of several cities.  I always take my dog outside for a potty trips, several times daily.  I always look at the stars and scenery at night as I wait for my dog to finish her business.  I am very familiar with the landscape of stars in relation to their position in the sky, as I stated I look at them daily at night.  I had noticed three not seen before lights that appeared to look like stars in the sky. They looked like part of the star scape, but I felt they looked odd based off their formation and distance to one another. Visually they appeared to be in proximity of being over the unincorporated part of Riverside and the Lake Matthews area. Going back to factors that caused my attention, were that the 3 lights or star like ! lights, were equal distance to each other, but not that far apart for being stars. The 3 lights appeared to be part of the star scape at first glance. The lights were not only equal distance in width, but also on the same plane horizontally. That is probably what stood out to me most. They looked like 3 separate stars but strangely on the same plane. I asked my adult son to come outside and told him and pointed out, those 3 stars are never in the sky (as I look daily). We watched for 10 minutes. Nothing changed. I thought “okay” maybe they are stars and for whatever reason they are visible today and were not visible to me in the past. This was about 8pm “ish” at night. I then went inside. I came back out at about 830pm just to check on the 3 lights again. The 3 lights that had appeared to be stars, were now gone. All the other stars in the sky were still visible as normal, but the 3 star like lights had completely vanished. There was no change in weather etc. in that span o! f time. I brought my adult son back outside for confirmation. ! We both agreed that the 3 lights had vanished.
