The guns fell silent at the 11th hour of the 11th day of the 11th month in 1918.

But they did not stay silent long.

Remembering with gratitude all who have served.
Thank you to those who serve now.

Field of Poppies, Gustav Klimt 1907

"Night after night goes by: and clocks still chime
And stars are changing pattrns in the dark"
from "Two O'clock" by Christopher Morley

Why then turn the hands backward or forward seasonally?

#Astronomers
Try your #Adsabs accounts & libraries in #SciX by midnight on the #crossquarterday to obtain a lifetime of necromancy-free results (limited time offer)

To those who celebrate #Samhain, may you have the #blessings of #harvest, #hearth, and #home this #season.

To those who celebrate #Halloween, may you have more treats than tricks.

Roughly halfway between #autumnalequinox & #wintersolstice, we celebrate the changing #seasons, the coming of #winter:
#Halloween
#AllHallows
#DíadelosMuertos
#samhain
the 4th #crossquarterday
Take a moment to enjoy the #sky, as did those who worked out our #calendar.

Astrophysics version of SciX includes Classic tab. I know it's not exactly the ADS of my graduate school days but I read you ...

#SciX has a proposal search for awarded proposals, which we are matching to papers.
October 3, 2025 at 2:04 PM
#SciX has a filter for planetary features named in the #USGS Gazetteer of Planetary Nomenclature. We are tagging all the #astronomy and #planetaryscience papers using NER and working on new categories.
October 3, 2025 at 1:55 PM
#planetaryscience is included in the #SciX #astronomy collection, as it was in #ADSabs. We are working on breaking out a separate collections for planetary science and #heliophysics.

#SciX lets you pick a discipline-specific interface, with some different tools and vocabularies for each community. Your selected discipline should boost more relevant results.
October 3, 2025 at 1:46 PM
#SciX is where we are doing new development, including discipline specific tools.
SciX default sort is "relevance" rather than date, but you can change that.

To those who celebrate, may you have a meaningful fast and a good sealing.

For those who celebrate, Shanah Tovah and all good things in AM 5786.

The #Jewish #calendar synchronizes #lunar & #solar cycles.

#newmoon was Sunday. #AutumnalEquinox was Monday. #RoshHashanah began Monday at #sunset.

Fewer trees would make more impressive #sunrise at UMass Amherst Sunwheel

Tell #time at #night during the Golden Age of #Piracy?

Of course, just consult your #nocturnal #star dial.

You'll also need to find #Polaris & #UrsaMajor or #UrsaMinor.

Incredible #sailing under the bridge last week.
Hope the swabs had a meaningful transit outbound.

For those who celebrate, may you draw strength and vitality from the summer solstice.

Solstice from Latin sōlstitium via old French

sōl (sun) + participial stem of sistĕre = stand still

according to OED

Thank you, @rebeccacharbon.bsky.social for an eloquent summary of the far-reaching effects of the US Nautical Almanac Office 1869 eclipse expeditions and their attempts at "physical astronomy"

#LaborDay in Austria falls on a #crossquarter day, roughly halfway between #vernalequinox and #summersolstice, as the days continue to lengthen.
