Advance notice regarding the super moon; Ad on Finding location of ships at sea


Greetings from Palmia Observatory (offsite in Ashdad, Israel)

Well, we have made several earlier posts, primarily of the vacation kind, with just enough touch of astronomy to allow its inclusion in this post.  You can always take a look at those posts if you are interested.  In the November 13 post, I talked about an epiphany I had regarding how the Einstein equations of general relativity give more appropriate interpretation for the doppler shift for the expansion of the universe.   This post is just a quick announcement to be sure to look for the giant moon tonight and this announcement is made possible because




of the difference in our time zones.  Ok, ok, you already knew about it from Sky and Telescope or other sources, but I couldn't resist trying to take a photo of it with just my cellphone.

Ok, ok, it’s just taken with a cellphone, but you might take this 10 hour "advance" notice into account for your planning purposes.

By the way, given that we amateur astronomers rely on catalogs of positions of celestial objects, did you know that a database of locations of ships on the Earth is also available?  We were out on our cabin veranda this morning and saw this strange looking ship, "LSS Success".  Wondering what type of ship it was, I googled the name and found a website that tells all about the ship and its current location.  It turns out it is a livestock transport ship.

Surprisingly, when I inspected the map, the location of our ship, Viking Sea, was shown right there at the next peer.

And surprisingly just across the dock is the cruise ship from which the ship was spotted

So, for ships at sea, that do not purposely want to be and remain hidden from view, it is possible to find exactly where they are located.  Pretty neat!  It's sort of like astronomy and astrometry.

Until next time,
