Observing Mercury’s Transit Across the Sun

There’s a very special event occurring on Veteran’s Day, Monday, November 11th, between approx. 7:30 AM and 1:00 PM: the transit of Mercury, when that planet can be seen crossing between the Earth and the Sun. A transit is a fairly rare astronomical event; we earthlings can only observe Mercury and Venus doing so. The last time there was a Mercury transit (only 13 or 14 per century) was in May 2016 and it won’t happen again until 2032! Venus transits are even more rare: last was in 2012 and the next won’t be until 2117!

Weather permitting, on Monday, November 11, 2019 from 10:00 AM until Noon, join Montauk Observatory astronomers at the observatory (next to the Tennis Center at the Ross School) to get a safe look through solar telescopes (donated by Meade and Celestron) at Mercury’s transit across the Sun.

Please remember that looking directly at the Sun without the appropriate equipment can result in damage to the eyes.

This is a free, family, fun event–not to be missed–but donations are appreciated!

Please park in the lot at the west end of the Tennis Center

To register:

Montauk Observatory (MO, soon to be known as Hamptons Observatory), a 501(c)(3) NYS nonprofit that relies on public support, has served the South Fork since 2005. Its mission: to foster interest in science, particularly astronomy, through educational programs. Lectures, star parties, portable planetarium shows and other events are held throughout the South Fork, often in collaboration with other nonprofit organizations that host our events at their facilities. MO has established the first astronomical observatory on the South Fork (on the campus of the Ross School in East Hampton), complete with Long Island’s largest research-grade telescope; these facilities will soon be accessible over the internet to students, teachers, researchers and the general public. While Montauk Observatory offers all of its programs free-of-charge to encourage participation regardless of economic status, it still needs funds to operate. To make a tax-deductible donation to support our programs (or, for a donation, to arrange a private star party or portable planetarium show), or to join MO’s list for event notices, please visit and click on the Donate button or email
