Today I successfully captured the Sun – through a chromospheric telescope, and through an ordinary telescope with an wideband aperture filter. There was a faint haze over the city, but it even helped – the earth’s surface was less heated. Interestingly, the spot AR 2738 made a full turn and returned under the name AR 2740. In fact, this spot has existed since March (AR 2736), that is, for several months already. I have never seen such long-lived spots.
