If the LSST telescope, the Vera Rubin telescope, is in the Southern hemisphere, and the few Palomar surveys are in the Northern hemisphere their overlap will be reduced a lot.

I’m guessing as a sky survey goes if you can cover most of the sky one should have a large enough sample size.

But no one has discussed, they’re smart reporters it’s either common knowledge or they don’t think muddying the waters helps.

An LSST for the Northern hemisphere?

I guess not, I wouldn’t have thought there any good sites. But so much is being built in Chile it does miss out the the most northern bit.
