Transit of Mercury
November 11, 2019 @ 07:30 - 13:00
There will be a transit of Mercury on November 11, 2019.
Many of you may have seen the Transits of Venus and certainly the last Transit of Mercury which was became a bit cloudy in Delaware at the end. If you love the speed of a lunar eclipse you’ll be thrilled by this 5 and a half hours transit.
In Delaware this transit will already have started and will be mostly observable (weather permitting – prediction is for 40% cloudy). The good news is that it is cloudy 61% of the time on this day.
A group of Stargazers and anyone else interested will meet at Woodland Beach around 6:30AM although since the even will last until around 1PM you could arrive later. Telescopes with good solar filters are welcome.
“Drive on Rt 6 out of Smyrna, DE until you can’t drive any more.” The beaches are private so don’t walk or set up on them without the house owner’s permission.
The current (as of April 25th) table gives transit information for Philadelphia rather than Dover.
All times are local. Times are 24hr, altitudes are degrees. Table was produced by “2019 Transit of Mercury” by Fred Espanak from the Observers Handbook 2019, and http://www.eclipsewise.com/oh/oh-tables/tm2019-Tab03.pdf
