NASA/JPL Multimission Computer Control Center Clock
This neat program was used at Jet Propulsion Laboratory in Pasadena. It could be synced with NIST or USNO and also compensated the drift of the native DOS clock.
Voyager 1 will reach a distance of one light day soon - after ~18.000 days.

#OTD in 1877, Deimos (Mars II) was discovered by American astronomer Asaph Hall at the United States Naval Observatory in Washington, D.C. Deimos is the smaller and most distant of Mars' two natural satellites, with a mean diameter of 12.4 kilometers.

Isabel Martin Lewis was born #OTD in 1881. The first woman to be hired by the USNO as an assistant astronomer, she worked on eclipses. She held regular columns in several magazines to popularize science and astronomy.

I also saw some pretty cool obscure stuff through my 25cm telescope. I'll add those observations to deepskylog.be when I feel like it :p Gotta catch up on some more sleep first.

I went to look for the time of summer solstice. AI is compromising the results of basic astronomical information. I saw two clusters of answers and a third result.
The US Naval Observatory says 2026-06-21 01:24 PDT, hopefully the USNO is still accurate but who knows anymore.
