A US Air Force spy plane has been flying circles above Seattle for over a week. The military says it is on a routine training mission, while aviation analysts speculate it could be testing new surveillance technologies.

I agree, it could be monitoring the radiation and possible plume.

I have not heard of anything happening out of the ordinary in Fukushima, but with the law in Japan about releasing information... that does not mean nothing actually happened.

The Seattle EPA sensor shows intermittent data since Aug 1. Off for 2 days, then a 13 hour gap, then high readings for a few hours, then off again. We don't know what happened after 2:17 on Aug 1 (the readings were normal then). Was there an equipment change or a calibration done? We are not likely to find out if past experience is any indication. Regardless of this particular station's data, nearby Geiger tube stations don't show similar increases (uRADMonitor, Safecast, Gmcmap, Radioactiveathome, Radiation Network), nor the Canadian Gov't gamma stations, so this one station *may* not reflect actual conditions.

I'm not sure how exactly NETC reproduces the EPA's range 3 data when it's intermittent; Radnet's CDX site is currently offline so I can't see the actual data points with time stamps, just the 4 month Radnet graph. I have a feeling that NETC may not record data that has resumed after an outage, until some number of valid data points have been seen, so the EPA graphs recorded here may be missing a few data points.

Seattle's EPA data from Radnet is stable again, showing an outage of some 18 hours between Aug 1 and Aug 2. It also shows a general increase in readings since the outage, but the reason is still unclear. The other intermittent data seen after Aug 2 are gaps in the NETC data, not in the EPA data. These gaps could have been due to Radnet's CDX site being unavailable when NETC queried for the Range 5 data. Here is the EPA data formatted like NETC:

Here is NETC's data for the same site, showing the gaps:

This is not a complaint by any means, just something to be aware of. The EPA can be late posting their data (sometimes days late), and NETC will I think miss that data as a result. As for the reason for the increase in readings here, my guess is there was a sensor equipment change based on the outage just before.

Thank you for your research. You told me something that I didn't know.
