Ozone fringe during the eclipse

I imaged the total lunar eclipse on 2026-03-03 remotely using iTelescope.Net T14 (0.10-m f/5.0 astrograph + CCD) at Utah Desert Remote Observatory at Great Basin Desert, Beryl Junction, Utah, USA. Image: stacked 3x10 sec. R+G+B, at the beginning of the total phase. The peculiarity of this moment of the eclipse: blue ozone fringe on the umbra edge, and every time during total eclipses it looks interesting.
