I stumped Perplexity with the question "When was the first sunrise after September 13, 2018 at Tycho Crater on the Moon?"

Quote:I can’t determine an exact clock time or Earth date for that specific sunrise with the information and capabilities I have.

To answer precisely, one would need:

• A detailed ephemeris for the Moon’s rotation and orbit.
  
• The selenographic coordinates and local topography of Tycho Crater.
  
• Software that can propagate the lunar geometry from 13 September 2018 onward and solve for when the Sun’s elevation at that location next crossed from below 0° to above 0°.
  

In principle, you could get this by:

• Using a professional ephemeris package (e.g., JPL Horizons via suitable software) to compute the Sun’s apparent position as seen from Tycho’s coordinates as a function of time.
  
• Including local horizon/topography (Tycho’s rim and central peak) to refine when direct sunlight first reaches the crater floor or central peak.
  
• Numerically finding the first time after 2018‑09‑13 when the solar altitude becomes positive at the chosen point inside Tycho.
  

Without access to those tools and data right now, I can’t give a reliable numeric answer; only this procedure to obtain it.

My apologies for not posting a pointer last week.

Chapter 1 of 5 vs 5, "The New Kids in Town", went up last week.

Chapter 2 of 5 vs 5, "Getting to Know You", went up today.


Yes, this is the story that I didn't finish before we rebooted the franchise...

Nathan Fillion has just announced that a Firefly animated series is in development. The original cast is returning to do the voices, and some character design artwork has been made public:

   

Bill Kurtis retires as 'Wait Wait...Don't Tell Me!' judge and scorekeeper

He is 85, after all. His final episode (unless he comes back for a special occasion) airs May 23.

You've heard his voice. But if you need a reminder:

Dad's been in the hospital this past three and a half weeks after a fall that saw him with a cracked vertebra, along with some other compl9icating factors, age also being among them as he's near ninety. Managing pain has been a balancing act due to that, so medical consent and so on has been upo to me by proxy, though we have talked about it before so I have some guidance on his wishes in that area. Tomorrow, assuming all the specialists involved still agree that going forward is a good idea, he'll be going in for back surgery to stabilize the fracture, to reduce the risk of moving the wrong way and worsening it or damaging his spine, and the doctors are confident but there's always some risk to any surgery, and the margins for error get lower the older the patient is.

I am not a religious person, but I know Dad does have notions about faith that roughly add up to not needing to be in a church to be heard and not needing a preacher if there's any message traffic the other direction, and I know he'd appreciate any well wishes anyone cares to send his way. We could all use some good vibes; it's been a rough month all around. (World issues aside, I was also in the hospital for a couple weeks with some burns on my legs and diabetes-related factors, but am largely recovered and back on even keel at this point.)

This short story can be read on AO3

... and of course on the wiki too

... which I feel I should mention because AO3 was down most of yesterday.  All of our stories eventually make it to the wiki, but multi-chapter stories aren't moved into the public space until they're complete.

Chapter 1 of this story is now available on AO3.

Had an old Muppet Show clip pop up on Youtube, Lynda Carter singing 'Orange Colored Sky' by Nat King Cole.

And suddenly pictured Doug's meta gift causing various pyrotechnics to go off in his area of effect.  No serious damage caused, but quite distracting

One does not simply...

More Alt+F4, with emotional payoff for all the shipteasing at last. In Alt's special way.
