周二晚间，拉斯维加斯南部和南加州东部天空出现如流星般的一束亮光，最远到北加州的贝克斯菲尔德（Bakersfield）和萨克拉门托（Sacramento）都有人说看到这个现象。
美国战略司令部表示，大约美东时间周二晚上9:08的时候，俄罗斯SL-4火箭再次进入大气层，正好处在亚利桑那州的上空，形成了让大家惊讶的“火球”现象。
他说，俄罗斯的这枚火箭是周一发射的，周二晚上火箭箭体再次进入大气层后到哪里去了，目前仍是未知数。
战略司令部的发言人马丁‧奥唐奈（Martin O'Donnell）中校说，联合太空运行中心正在追踪这枚火箭和另外16,000个其他物体。

Wow!! #Shootingstar in #LasVegas has green and blue sparks coming off of it! #alien #extraterrestrial #spacejunk #ufo --- TV Stations and News stations you can syndicate this but please give our profile a shout out -- this was before it began to break up over Las Vegas at Ft Apache and Blue Diamond Rd at 6:09pm Pacific Time -- our little 13 month old girl now has her third word "Wow!" after seeing this earlier. I have a longer 40 second clip if you want it, it shows how low it was and slow moving it was and its Sparks and colors, please comment to get in touch. This was shooting right near our house videos from the driveway as we pulled in. It was a big burning blue and green ball of flashing electrical gas fire and started breaking up over what looked like near the Hoover Dam. It was shooting toward the south east from the north west very slowly and glowing! It was so strange! NEW ALERT: According to a French outlet it is been found to be an old Russian rocket re-entering the atmosphere.
