MIT Henge 2026

About this event

Observe the sun as it aligns with the Infinite Corridor!

This twice-yearly astronomical phenomenon is viewable from the 3rd floor of the Infinite, on the Building 8 end of the hallway, weather permitting:

• Tuesday, November 10, at approximately 4:19:23 pm

• Light refreshments to follow in Lobby 13

Safety, Viewing Tips + Etiquette:

• Warning: The fact that the sun is at the horizon does not mean that it is safe to look at for more than a moment. Do not injure your eyes by staring at the sun. Use appropriate filters or glance only for a moment as you would at the sun up in the sky.

• V iew from the Building 8 end. Don’t go up to the Building 7/Mass. Ave. end of the corridor. You won’t see anything special there, and you will prevent others from seeing.

• Arrive early and don’t block the corridor. Especially given the apparent systematic tendency for predictions to be 5-8 minutes late, it’s best to arrive 15 minutes early. This helps make sure you’re not trying to scramble for a spot and blocking somebody else’s view. Above all, do not walk in the corridor in front of all the people trying to catch a glimpse of the sun.

• Don’t leave until the very end. People who take a picture in the middle and then leave block the corridor for those still observing. Some people observe for the entire span in which the sun is even barely visible; leaving early blocks their view.

• Use the third floor. The 3rd floor has the best view because it has an uninterrupted sweep of corridor, and because it is the highest usable floor. You can’t see anything from the fourth floor because it doesn’t go through.

• Let others see. Not very many people can get a good view of this phenomenon at once. Once you have seen, get out of the way and let others look.

• Stand in the stairwell. The place that has the largest unobstructed angle of view of the sky is the stairwell just below the third floor. Get your eye right by the edge of corridor floor. Great view? Now give someone else a chance.

• Don’t hurt your eyes. See the warning above.
