On February 3rd and 4th, the temporary cover for the storm-damaged 36-inch refractor telescope dome at #LickObservatory was completed: The time-lapse https://www.youtube.com/watch?v=mEwnZ-YFEqE shows the installation of the final waterproof layer on the dome slit cover and metal flashing around the edges to ensure that wind or storms will not remove the waterproofing.

#LickObservatory needs your help:
"Early on Thursday, Dec. 25, severe winds gusting up to 114 miles per hour tore across Mount Hamilton. The multi-ton shutter section fell outward onto the roof of the Great Hall, crushing several structural beams.
The Great Refractor telescope was not damaged during the incident, but its precision lenses and electrical systems could now be vulnerable to rain."They're looking for donations: https://give.ucsc.edu/campaigns/53679/donations/new
(Just an interested bystander)

Lick Observatory Damaged
I missed, until now, the news that on Christmas Day, high winds accompanying a violent storm seriously damaged the historic Lick Observatory.
The gales were strong enough to rip one of the shutters from the dome of the 36″ refracting telescope and send it crashing onto the roof of the adjacent building.
The Observatory remains closed to the public while the structural damage is assessed and repairs made. Fortunately it seems nobody was hurt and no instruments were affected.
Here’s a video of the detached shutter being removed
https://www.youtube.com/watch?v=kYooaiylVEg
The Lick Observatory is located on Mount Hamilton near San Jose in California. A donation by San Francisco millionaire James Lick enabled the construction of the 36” (diameter) refractor, the most powerful telescope in the world at the time. The Observatory was almost destroyed in 2020 by a wildfire, but the new incident is the most serious damage in its 137-year history.
As I blogged about here, the Lick Observatory played an important role in the development of our understanding of the large-scale structure of the Universe, specifically with the creation of the Lick galaxy survey prepared by Charles Donald Shane and Carl Alvar Wirtanen and published in 1967 (Publ. Lick. Observatory 22, Part 1). In my more poetic moments, the image on the left puts me in mind of W.B. Yeats: Had I the heavens’ embroidered cloths.
That catalogue was still proving a useful resource well into the 1990s; I was part of various analyses of it myself, starting with this paper from 1991. It was eventually superceded by the arrival of large-scale galaxy redshift surveys, but it remaining an amazing achievement.
The Lick Galaxy survey was not performed with the 36″ refractor mentioned above, however, but by twin 20″ Carnegie astrographic telescopes housed in a different dome. As far as I know, these were not damaged in the storm.

Historic #LickObservatory closes to public following significant wind damage: https://news.ucsc.edu/2025/12/historic-lick-observatory-closes-to-public-following-significant-wind-damage/ - early on Thursday, Dec. 25, severe winds gusting up to 183 km/h tore loose half of the shutter on the 140-year old 36-inch Great Refractor dome; no one was injured.

Our company observes MLK day, so I did some avoidance by riding up Mt. Hamilton again. Riding to the beginning of the climb, we had some gusty winds that almost persuaded me that climbing would be a bad idea. Weirdly, the winds were stronger at low levels with very little towards the top.
It was warmer than last time at the top and I again enjoyed the somewhat hidden courtyard. This time I spotted the plaque thanking the Jon Graff fund for helping with the maintenance.

@futurebird More than 40 years ago, the #CityOfSanJose agreed to switch all of the street lights to low-pressure sodium-vapor lamps, because their light is a monochromatic yellow with a wavelength near 589 nm that could be filtered out by the telescopes at #LickObservatory. They were also more energy efficient. The effort was somewhat half-assed, since upscale mechants didn’t like the aesthetics and the PD didn’t like the loss of color—you can’t tell a purple car from a green one. Early LEDs were monochromatic, I think, but white LEDs are not.
