Counting down for the Mercury Transit on November 11th, 2019. In the afternoon of November 11th, planet Mercury will be moving in front of the Sun. The planet will be seen as a small spot on the Sun's disk. Watch out : do not look without protection to the Sun! Use solar eclipse glasses or a special solar filters to watch this.
If you miss this one, don't worry, the next Mercury transit will be on November 13th, 2032.
