Wish the Observatory Good Luck!

60 inch at mount wilson The fires are racing up the sides of Mount Wilson as I write (19:38). They expect the burn to get to the top sometime in the next few hours, and yes, I imagine it’ll affect the Mount Wilson Observatory in some way.

[Update (20:59): You can get regular updates from the director at this page*. Seems that fire crews will remain on site for when/if the fires sweep through the grounds. ]

All of the working scientific equipment, including the solar telescopes and of course the historic telescopes (the 60 inch is pictured to the right) with which astounding discoveries were made about our universe (such as the fact that it is expanding, and the fact that the universe is vastly more than just our Milky Way Galaxy) are presumably in some danger, as well as support buildings of various kinds. I’ve no idea how much since I do not know what fire-proofing measures are in place up there, although I am sure there are several – such as keeping brush away from the buildings themselves. Here’s a camera up there on one of the solar telescopes where you can see regularly updated pictures that it snaps. I grabbed this one just now (click for larger view):

So keep your fingers crossed for luck for the instruments, and of course for all […] Click to continue reading this post →

Smoke

fire_sunriseThere’s a remarkable amount of smoke in the skies here in Los Angeles. Strangely there is little or no wind to accompany this super-hot day, and so the smoke is largely staying over the region where the fires are – the San Gabriel mountains, North of La Canada, Altadena, etc.

There was a bit of movement of the smoke overnight, and early this morning (while the sun shone dull and red like a sunset instead of a sunrise) there was some ash fall over where I live (I was working outside on some writing while it was still cool), a good number of miles away from the fires, in the city of Los Angeles itself, but this seems to have gone away. So there are clear skies in all directions, and then ominous-looking mushroom clouds in one direction. It is odd. This stillness is the reason the firefighters are having a lot of difficulty fighting the fires, actually – the smoke is affecting visibility for the various ground and airborne crews. There’s a lot of concern about what the fires will do next, (including a threat to the Mt. Wilson Observatory) and so let’s all keep out fingers crossed for luck. [Update: 6:30pm – I’ve heard that they have no choice but the let the fires take Mount Wilson. I hope that the Observatory survives ok. If you’re not familiar with the significance of the Mount Wilson Observatory, read here and here.]

Here’s a recent (about 5:00pm today) shot of the mushroom clouds of smoke. You can […] Click to continue reading this post →
