24Nov18, November is the wettest month for us in Singapore. It has been raining almost every day. Today we had bright sunshine but the Sun was covered by fast moving clouds throughout day. I was glad to have the equipment out and some images after patient waiting. However the seeing condition was poor and the passing clouds degraded the images.

A new flaring sunspot was spotted near the middle of the solar disk in white light,(solar surface) Calcium-K (solar lower atmosphere) and H-Alpha (Upper atmosphere) wavelengths.
