X-Ray Flare Detected!

X-Ray Flare from Sun

Starting at 4:53 AM ETD on 6/20 my x-ray detector started logging x-ray counts above background. The greatest single bin peak was σ5.5893771396, which is a valid detection by nearly anyone’s standards.

And then I lost power!!! Yes, my house lost power for a brief moment. The UCS30 and my entire gamma spectrum were shut off. My laptop continued recording the x-ray and Geiger counter readings, luckily. I may have had a nice gamma detection, but I will never know.

Correlating the x-rays with the Geiger counter, I found this:
