Cable TV is supposed to give good images and no static. But Comcast/Xfinity in Falmouth MA is sending out this crap. They must lose their franchise!
For the old folks at #AAS244, the map is wrong when it says the Wisconsin room is the 40+E lounge. The actual 40+E lounge is the Dane room. And it's nicer anyway.
I'm at #AAS244 and will give a talk on Tuesday, 219.02, about the coldest known brown dwarf, W0855-0714. This "star" is cooler than room temperature. With 23 epochs from WISE & NEOWISE the W1 flux can be estimated giving a W1-W2 color of ~5.6! 🔭
Earliest sunset of 2023 in LA. More Northern latitudes still have more days before the evenings get less dark.
Dear @MayorOfLA, stop the emergency phone broadcasts! I have received 4 today, very noisy, and only the first was warranted. Unless you stop until there is new information, I will turn them off.
ISS just raised its orbit 1 km to avoid space debris, so it is now only ~3 weeks to the time ISS and WISE are at the same elevation. WISE is dropping ~5 km/month due to atmospheric drag.
This morning I saw Tiangong, the Chinese space station, at mag -2, and I didn't even have to get up superearly, thanks to DST making sunrise so late.
I am finally getting a chance to watch @UCLAFootball this year since the @SDSU game is on @CBS instead of ESPN, which is blacked out by the @Disney-@Spectrum pissing match.
I wrote an entry on Ned Wright's cosmology tutorial News of the Universe explaining why Gupta's 27 billion year old Universe model is hopeless.
Falcon 9 launch of Starlinks went over LA. Left, the second stage emerging from behind a tree. Right, 2 minutes later it was high enough to be lit by the Sun.
78 years since the Trinity test - 78 years of nuclear bombs.
The 4th of July barrage is going full bore and it's not even dark yet.
Happy #AsteroidDay 115 years since the Tunguska impact knocked down trees over 2000 sq.km.
Northern summer solstice! For once no June gloom, so I got to see the ISS pass by Saturn at 5:13 PDT. And @WISE_Mission finished the 19th sky coverage in its NEOWISE reactivation 5 days ago. Add 2 coverages in 2010-11 = 21 times around the sky. I'll drink to that!
In DC for the SSB meeting. Wanted to ride the Silver Line from Dulles to DC but it got shut down for weeks of track work 3 days before I arrived. Now the ride is back to the bad old 5A bus days. Long delays in traffic.
Ralph's (@kroger) live chat help service is totally useless, but when I called and spoke to a live agent she hung up on me without giving any help too.
Awaiting Frontier to fix my landline for the fourth time since February. Not good.
Now that the Public Health Emergency is over (5/11) I will retire the Journal of the Plague Year. But I also got my 2nd bivalent booster shot (6th overall) on 5/12.
