Emerging Flux Regions - 5th August

There were 2 small emerging flux regions visible today on out star.  At its height the EFR on the right also sported small pores where the flux tubes broke through the photosphere, in Ha and higher up in the chromosphere they manifest as darker and cooler regions of plasma that arc and follow the magnetic field lines.  Taken with the Coronado SM90ii double stacked with the Daystar Quark and the FLIR GH3 ICX916M camera.
