Spotless Sun these days. Regular and otherwise somewhat expected solar activity in this period since the last posts above. (For some details etc. e.g. cf. davenn's solar-relevant threads already quoted earlier ...). Approaching solar minimum. I received the following interesting one on my e-mail just a couple of days ago, with title 'The Sun is Dimming as Solar Minimum Approaches': "Space Weather News for Dec. 15, 2017 http://spaceweather.com https://www.facebook.com/spaceweatherdotcom THE SUN IS DIMMING: Today at the Cape Canaveral Air Force Station in Florida, SpaceX launched a new sensor to the International Space Station named "TSIS-1." Its mission: to measure the dimming of the sun. As the sunspot cycle plunges toward its 11-year minimum, NASA satellites are tracking a slight but significant decline in total solar irradiance (TSI). TSIS-1 will monitor this dimming with better precision than previous satellites as Solar Minimum approaches in the years ahead. Visit today's edition of Spaceweather.com to learn more about TSIS-1 and natural variations in the sun's electromagnetic output." The Sun is Dimming! ... Sounds "scary" but ... explained. Any comments?
