Re: Right NEA not NEO...
You're right I meant to type NEA not NEO as a Near Earth Object can include any Long Period Comet that will pass the Earth in the future.
As I read Mazanek's report that is not what I came away with. The Moon blocks viewing in areas as it is physically between you and the region of the sky you might want to view. Its like you're in a lighthouse where the light rotates every 28 days. EML1 or ESL1 don't have this exact problem.
