New Sunspot on the Eastern Limb - 5th April

When I looked on the suns eastern limb with the Airylab HaT, this tell tale signature of prominences told me that while I couldn't see the sunspot itself directly there was a new active region coming around the limb.  This was with a Daystar Quark and PST etalon double stacked at a focal length of 5.6 metres with the PGR BLackfly GigE IMX249 camera.
