      LSST claims it can detect asteroids closer to horizon and has done simulations showing that. Yet to be demonstrated in practice.

      My point is Venus is irrelevant in context because seeing planets and asteroids are not comparable, by many orders of magnitude.

      Besides, this Venus pt has nothing to do w/ the new paper. This is Nathan's March PASP published paper that passed peer review.

      Curious: did you even look at that paper? Here http://arxiv.org/pdf/1506.07085v4.pdf … or http://iopscience.iop.org/article/10.1088/1538-3873/128/962/045004/pdf … ? Search for the word "venus".

      Did you read the context of where I mention Venus in my article?

      The space-side is mus-characterizing the ground-side capability. And then you mentioned a planet to make an asteroid point. /2

      It was Nathan's anecdote to counter an assertion by Amy that LSST could not spot any asteroids within Earth orbit.

      But 'any' is a very strong word. There are twilight and dawn, so LSST will get some. /2

      Myhrvold said Mainzer claimed LSST couldn't observe anything less than 90 degree angle (forget exact term).

      Okay, let's not get into he said she said. Mainzer would be insane to make such a claim. For that matter, anyone who has seen /1

      Ivesic said that was a common misconception about LSST among asteroid researchers. I really did do a lot of reporting.

          The Tianhe-2 supercomputer can also do the work of a powerful gaming PC. There is a point of efficiency and optimization. /2

          LSST will find more than a few NEOs. Even the Grav/Mainzer/ Spahr paper said 60%.

          LSST will map half the sky like no telescope ever before, and that's great. I will get some asteroids, that is great. /1
