Well, the thing is, as far as I can tell, FD just forgot all of them except the Crab.

And there are not that many historical SNR's anyway, so the number of targets would be limited ...

294 targets spread all across the galaxy doesn't seem that limited to me: http://www.mrao.cam.ac.uk/surveys/snrs/snrs.data.html

In principle, the tycho nova conpanion star is a lone G2 star with high proper motion. "wandering star".

So it should not be in association.

This my assumption too. Any G2 that isn't the primary star in it's system is something I'm ruling out. I doubt that Tycho G is a binary (or trinary, etc.) so even if the G2 is the main star I consider any multiple star system to be a less likely candidate. If the G2 is a lone star but there are planets with life on them then, this too, lowers the probability that this could be Tycho G. And remember: ELWs, and Ammonias aren't the only stars containing life. Quite a few Gas Giants do as well. Most likely candidate will be a single star near the "heart" of the "corridor" of quardinates.

Some discussion on Discord as to identifying Tycho G by his age, comparing it with the age information on scanned G2 stars given in System Map.

However the only direct evidence for the age of Tycho G is in this ancient article posted by Cmdr Raymondo the Great:

http://www.skyandtelescope.com/astronomy-news/tychos-supernova-companion-discovered/?c=y

This gives the age of Tycho G as: 'several billion years older' than Sol, which would make him at least 7,000 million years old (or 7 milliards where I come from). But this appears entirely to have been a wild guess.

Even so, Tycho G could be of similar age to the SN1572 progenitor white dwarf. If he was as old as 12,000 million years, he would be a Population II star interloping from the Thick Disc into the Thin Disc, and therefore by association so would SN1572 have been. Tycho would have observed the late explosion of one of the first stars to form in the Galaxy.

Yes; once we've got the raw data we'll apply all kinds of filters: nearness to the correct right ascension/declination, temperature, age, solar radius, solar mass, etc.

5/5, lone G2 star o7
So, there is a motion "wandering star" when you do a scan ? Never paid attention to that before.
Click to expand...

Unfortunately, no. Even fast moving stars are to slow for it to be worth Frontier's time modeling it.

Tycho's SN was caused by a white dwarf that was consuming material from Tycho G. Once it accumulated enough mass the white dwarf exploded ... leaving nothing behind. No gravitational force to keep Tycho G in orbit. Imagine taking a yo yo and twirling it around your head. Then let go of the yo yo. That's what happened to Tycho G.

MISSION UPDATE 16 NOV 3302

Although the official waypoint for today is Kappa Cassiopeia many of you have made the effort to head toward the search corridor for Tycho G. I've made my way there myself so I could record a video explaining the search methodology. Recording this video became very frustrating. Windows refused to record audio from my microphone so I rebooted. Windows update took over from there and turned my PC into an unbootable pile of mush. I don't know why this PC hates windows update so much. After repairing the installation (again, I do this almost every time windows updates) I was back online and, after much frustration, got my microphone working.

Here's the tutorial:- redacted

Great Video Tutorial Thank you very much.
The routeplotter can be of a bit of assistance though. When selecting the startypes (G, White Dwarf, Non Sequence) just add the last checkbox. ("Apply Filter to route")
In the Plot route panel now select the FSD Boost and toggle the level adjustment until the range of 60Ly is reached (at least)
Now you just have to follow all possible routes on the map to all the G Stars in that range and bookmark them
This helps maybe so that you wont select the ones too far away or worse, forget one ;)

I'm not sure this is entirely true.

I'd say any that's part of a group that orbit each other are for sure not candidates.

However the system I just scanned had a lone star several 100 thousand Ls away from the drop in. I would suggest its possible that were that star a G (in this case it wasn't) then that could possibly be a wandering star, given the number of stars in the area and it's speed it could possibly "pass through" another system but far enough away it doesn't orbit the main star or become it.

Cool video on neutron and strange stars, would recommend watching the entire thing. When he mentioned "10,000 light-years" and "Cassiopeia", I jumped, heheh. 3C58 (or SN 1181) and its nebula also don't seem to be in the game. Coincidence? Probably. (Skip to 7:29)

Wow so good man, an in depth exploration of something local and famous is something this community needs. Hope it's on the expedition hub

Thanks Doc!

I do believe that Erimus has placed it up on the Hub. I certainly an enjoying the search. It's kind of like a little treasure hunt!

Hello everyone

Due to real-world stuff I can't go on the expedition anymore. Sorry! Good luck :)

No problem. Remember: if RL stuff changes you're always welcome back!

At this rate it doesn't look like I'll make any of the Tycho G co-ordinates before someone else surveys them; I'm just passing between the Heart and Soul Nebulæ now and am about 5,000L-y from the next co-ordinate set, which I'm not sure it's even possible to get to.

In the meantime, talking of Heart and Soul, someone had the idea for a theme song for the Expedition. Whilst I'm not going to directly suggest one, I am going to use the idea as an excuse to inflict my exquisite taste in music on the group, with a selection of daily tracks to while away the light-years as we scour this increasingly dark and sparsely-populated region of the Galaxy, all with appropriate space or searching space themes. Just as the legendary ancient Lunar astronauts did. Feel free to join in.

So without further ado, here's today's track: 'It Never Was You' by Kurt Weill, sung by Judy Garland. Take it away Judy—

Okay. It looks like today's announcement is for a COMPETITIVE exploration CG. This changes things. We need to keep an eye on this and, if it looks like it might even come close to CoR losing this thing, some of us should make an attempt to deliver our data to HR 6421 to lend a hand and then return back here to finish our task.

I know it sounds odd for me, a Federation citizen, to be campaigning against the Federation side of a community goal but remeber; Karl Devene has been no friend to this expedition. He denied our request for data that could have truly narrowed our search down. I know that is something that I won't ever forget.

Aye I'm with CoR on this one as an Indy Pilot

Problem is I can't see in game what the situation is. Is there someone who had to leave who went back to the bubble who could perhaps sign up and give us regular updates?

Like Diffin it occurred to me last night that I wasn't going to make the end of the line before all coords were surveyed - I'm still several thousand LYs from the nearest one despite covering several thousand last night, and don't have that much time to commit sadly. I'm going to turn around and head to EAFOTS, grab as much data as I can and then hand it to the CoR.

CLARIFICATION

It appears that Frontier is finally figuring things out and ONLY data from the three specific regions mentioned in the CGs actually count toward the CG. Nothing that we've gathered here on the search for Tycho G will count toward the CG.

No, this has been disproven. Any data counts - unfortunately ...

Personally I don't see that the CG should change anything. This Expedition was about different factions coming together. Now the Feds and the CoR are dividing us. Now I have to admit that I've never liked Feds, and I've always avoided all Imperial entanglements, including the CoR and their Imperial Princess. To hell with the CG and let's just get on with the Expedition... although...

Having said that, I'm at The Formidine Rift location Eafots EU-R c4-1 right now (as it was directly on my route) looking down the barrel of an Unregistered Comms Beacon having just failed to record a transmission of a synthetic female voice reciting military phonetic alphabet; my flipping audio recording software failed to activate. Very frustrating. Certainly someone on the Rifters' thread https://forums.frontier.co.uk/showthread.php/252932-So-you-want-to-know-about-the-Formidine-Rift-(Part-3)?p=4789729&viewfull=1#post4789729 should have caught it by now.
