Day Planet Mercury is transiting across the disk of the Sun
Planet Mercury is transiting across the disk of the Sun Quite impressive astronomical phenomenon - transit of the planet Mercury across the disk of the Sun - will occur today on 11 November 2019. The first touch of Mercury with the Sun will take place at 15:35 MSK, and, according to calculations, the ending of the transit should fall on the evening after the sunset at 21:04 MSK. Thus, the duration of the transit will last exactly almost 5.5 hours. Mercury will be in the center of the solar disk at 18:20 MSK.

Day Anti-flares on the Sun the eclipse season has begun on GOES satellites
Not very rare, and not less incomprehensible from it either the appearance of negative spikes of solar flares on the graphs are registered on the incoming data from space. The dips in radiation are not related to real solar activity in any way, but, do originate from the traits of the orbit of the GOES satellite which takes corresponding observations of the Sun.

Day During the course of summer 2019, there hasn't been a single flare on the Sun
Not a single solar flare of the x-rays class C or higher (a minimum level which is able to have an impact on Earth) has been recorded on the Sun over the past summer of the year 2019. Currently, this is the fourth-longest in duration interval in the modern history of observations when a complete absence of the solar activity has been seeing. The dynamics of the solar minimum is not yet alarming, notwithstanding the duration of the minimum which has already exceeded previous predictions when according to them the growth of solar activity was supposed to begin this summer.
