I was browsing the NEXRAD radar feeds (I'm not an expert, just figuring them out) and I came across the following signature (visit the link to view the radar image)
The radar in question was operating in clear air mode and the "ray" varies from about 0-16 dBZ. There were several of these all covering the Midwest, and I picked up one as far west as Kansas, at about the same return signal strength. Further west they weren't visible.
Could this be caused by a cosmic phenomenon?
I'm tracking it across the United States right now. I'll be following it below with updates.
- 9:16 PM: appears on KIND Indianapolis composite reflectivity
- 9:30 PM: appears on KSGF Springfield base tilt 1 and 2, KICT Wichita base tilt 2
- 9:31 PM: updated KSGF now shows only on base tilt 1, not 2
- 9:34 PM: now appears only on KICT Wichita base tilt 3? This doesn't make sense if it's a "stationary" cosmic object, that would mean it should be shifting to lower tilts. Might just be an outlier
- 9:37 PM: visible now on KDDC Dodge City base tilt 4, KICT tilts 2 and 3. Also now appears on KAMA Amarillo base tilts 4 and 3 (weaker on 3)
- 9:43 PM: visible on KICT base tilt 2 only
