Bright, very red, light flies south to west near Silver City, NM.Saw a bright, very red light approaching from the south, heading northwest toward the west - as if coming from Deming or Las Cruces and heading to Phoenix. It appeared to fly at about helicopter height and helicopter speed, but it made no noise and appeared only as a very bright, very red, unblinking light. The orangey-red or red color was pure with no other colors noted. It was at least twice the size that Venus appears, possibly more. It was visible for 90 seconds or more. The two witnesses are unsure whether it flew in a perfectly straight line, or whether it flew first toward the city in a more northerly direction, and then arced westward when it approached, or was over Boston Hill south of Silver City. Video was taken, but was hand-held and not very useful.
