Question (Describe all previous attempts to learn / understand) My girlfriend lost her little sister - Please help me keep them together in the stars

I know this isn't the typical kind of question here, but I've read all the rules and I'm doing my best to follow them!

Hello all!

As the title says, this year my girlfriend lost her little sister. It's been a devastating time to say the least but I'll spare you the details.

My girlfriend's birthday is coming up and in her room she has a certificate for a star named after her. I'd like to do the same for her sister, but I want to do it in a way that has more meaning than a name on a piece of paper. I know there are stars that orbit one another, but i also know it's not as easy as "I'd like a star that's next to this one".

The picture contains all the information I have on the star. I've tried putting SAO16436 etc. into star maps and similar, but haven't gotten any useful information, if any. I don't know how useful the rest of the information is to someone more knowledgeable than me, but sadly it's all I have on the matter.

So, I'm asking, please help me make this special. Please help me give this gift the meaning it deserves. It would mean the world to me. I'm open to any and all suggestions, even if its a different idea entirely!

Once again, I know this is a deviation from other posts here, and I apologize for that, but I can't really google "creative ideas for a situation like this"

Thank you all in advance!

EDIT: Thank you so much to everyone who's commented! Your ideas and pictures already moved me to tears and I'd hug each and every one of you if I could! I'll be sure to update you all once her birthday comes!

Caught a video of this object seemingly stationary above moons surface, any idea what it could be?

Space Telescope NGC 6357 from JWST

Telescope: James Webbs

Filters: f090w, f187w, f200w, f335m, f444w, f444w-f470n

Software used: Astropy, JupyterLab

OS= Ubuntu

Second time i used Astropy to process data from space telescopes. All was doing writing code in python in JupyterLab (you can run block of codes separately). I wrote code to study noise and background for each filters, then i stack them to get the final image in black & white and in RGB. Astropy lets you doing also some scientific processing, so i add the coordinate, study the shock fronts of gases and the noise SNR.

I wanted to make this post because i saw little to no post using Astropy as software to process data. I hope you enjoy it (and to not broke the rules).

Question (Describe all previous attempts to learn / understand) If the earth and moon rotated in the opposite direction would the colour of the moon in the night sky appear different?

0 Upvotes

The moon appears yellow or gold currently and I am assuming that this is because of the spectral elements of sunlight refract differently.

So if the earth and moon rotated in the opposite direction, would the opposite end of the spectrum alter the colour of the moon?

A short clip of the Orionids Meteor Shower captured by Arif Alblooshi (@3roof.A) during our event in Al Qudra Desert in Dubai.

Always amazing to catch a meteor streaking across the night sky! โœจ

Were you able to spot any meteors?

Question (Describe all previous attempts to learn / understand) Do the Line Features Have a Name?

Image from Wikipedia Commons

Not sure if this kind of post is allowed here, but I'm wondering if the line features directly below the three connected craters have a name? The three craters, left to right, are Wargentin, Nasmyth, and Phoclyides. The large crater on the left is Schickard. I've searched multiple Lunar feature databases, and those features are never marked or named anywhere I've looked. Thanks!

Used a Seestar S50 and all edits made using Siril. After edits, this is 370x10sec stack (just over 1 hour). Very happy with this one since it was nearly a full moon.
