Astronomical events in 2019.
I knew the orbit of the moon was elliptical but I did not realize there was such a difference between it furthest and closest orbit.
when it is close to the earth, it is apogee I think, as I recall from prior studies. the moon has quite a lengthy orbit as I recall. I forget what 1 day on the moon is equal to in earth years.
@AntaresRose One day on the Moon is 28 days on Earth which is why we only see one side of the Moon. Actually there is more to this as the Earth is turning as the Moon does so what I said is close but to actually describe the process the math gets complicated.
@AntaresRose Apogee is when the moon is at its' furthermost from the Earth. Perigee is at the closest. At its' closest it is 225,000 miles and at the furthermost, 252,000 miles
@starwatcher-al i knew you would straighten me out. thanks, i will have learned this again. How long is the moons revolution and orbit? I maybe pushing my luck, lol.
@AntaresRose For the moon to make 1 revolution compared to the fixed stars is 27.32 days as far as getting back to the same phase, lets say new moon to new moon is 29.53 days.
@dalefvictor I am speaking as a moon cycle from closest to earth to further point from earth and back. One long oval looking egg rotation. yes I know one rotation but we only see half the moon. I will go exploring later and see what I can find.
@dalefvictor, @starwatcher-al thank you so much!

Posted by starwatcher-alSolar minimum was in 2019 so the sun is ramping up in flares, spots and prominences.
Posted by starwatcher-alI missed the early phases of the eclipse but the clouds mostly left during totality. All in all a great eclipse. Next one is Nov. 8-22

Posted by AnonySchmoose The post-launch set-up of the new James Webb telescope has gone very well.

Posted by starwatcher-al Did you know that you can see Venus in the daytime?
Posted by starwatcher-alOne of these days I think that I'll figure out this Nikon.
