Ladies and Gents,
I haven't been following RADSAFE for quite a while, and please excuse me if someone else already responded with this.
There are couple of web pages that show solar weather. The second one below has a plot of 3-days of 5-minute solar x-ray flux values measured on the SEC primary and secondary GOES satellites.
Perhaps solar weather will help explain the anomaly observed in the airplane.
I wish you all Happy Holidays.

On a recent trip to FL from Boston, my RadEyeG measured 0.01 mr/hr on
the ground and 0.40 mr/hr at 35Kft during the day. On the return flight
the next night it measured 0.01 on the ground and 0.30 mr/hr. These are
completely unscientific since I probably changed locations relative to
DU ballast if any. Also, I don't know what energies were involved and
therefore can't correlate the response of the RadEyeG. Still it was

There has been some writing about dose rate measurements in planes. I
seem to recall that DU can be used as ballast in planes. Even though not
exceptionally active, I suppose that could affect measurements somewhat
inside a plane!
