Apparently a fragmentary #SunPillar 20 minutes after sunset last evening from Bochum, Germany, with the Sun more than 3° below the horizon: didn't know that this #AtmosphericalOptics phenomenon - #afterglow effects in a very complicated cloud environment. The pillar vanished only when the solar depression approached 4°.
