Hi Joe, I still think it would be prudent not to mention why you want these light curves. Just say you're looking at asteroid groupings.
did you ever look into those historical writings on the 1006 and Crab supernova events? If I recall correctly, the historical positions given don't correspond to the remnants. This is interpreted as simple error by the ancient chroniclers. What if they were right, or nearly right? I've a vague recollection that there's another nova from about the time of Alexander as well.

<br />Dr Joe,Palmer Divide Obs has the light curves. I have more info if you need it.
<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">
Brian Warner, one of their leading observers, has sent me his one lightcurve (really three on almost consecutive nights; counts as one for this purpose). I have yet to hear from their listed contact person. I suspect that only one relevant lightcurve was done there, though they might have, on somebody's computer hard drive, lightcurves done by others.
It would be helpful if others besides myself would send emails expressing interest (the names of the relevent observers are in the IAU Minor Planet Center lightcurve bibliography). I've only heard from one of the Europeans (Europeans seem to have done most of the lightcurves) so far; this particular European was, I gather, one of the amateur workers, and might not actually have possession of a lightcurve, though he is rechecking his records.

I haven't found any coordinates yet. If someone analyzing the old records, estimated a sky position (to the nearest 10 degrees or so) and time (to the nearest century or so), I might be able to make the case that it was a flareup of Barbarossa.

Subject: popular press says new space telescope might find Planet X
Date: Wed, 13 Jan 2010 13:19:01 -0600
The fourth paragraph, near the top of this Dec. 11, 2009, Daily Telegraph (U.K.) article by Andrew Hough, is:
"Some scientists [link, which doesn't work] also believe it [the Wise infrared sky-mapping spacecraft] could also identify a huge gas planet in the outer reaches of our own solar system, while it will also catalogue objects posing a danger to Earth."
Since Harrington's death, and the publication of Standish's ephemeris analysis, in 1993, there's been, I think, extreme prejudice against the "Planet X" possibility. Now, apparently, persons a mainstream newspaperman calls "scientists" tell him that there might be a *** "huge gas planet in the outer reaches of our own solar system" ***. Maybe this means desperation for funding, and a need to cultivate popular interest. Maybe it means that the naysayers have lost their dominance, that someone can speak of this possibility now without losing his job or being shouted down.
I've been announcing since Feb. 2007, that there is a massive planet, or rather, cold brown dwarf ("Barbarossa"), in distant solar orbit, which I've identified on sky surveys. I've been announcing for about two years that "Barbarossa" has a nebula, which I've identified from "interstellar" absorption of starlight, and from USNO-B star catalog statistics.
Sincerely,
Joseph C. Keller

Hi Joe, they don't have to have been a flare up of barbarrosa but genuine supernova. Your planet will have shifted the barycentre of the solar system. Of course there will be errors in the Chinese, Japanese and Korean records but those can be allowed for.

Oops[]slight mistake there on the date of one supernova, not a b.c. date but and a.d. date. Here's a link to an article on it. Note the paragraphs on a revision of spin rates being called for.

Another nova that should interest people on this board is this one, recently discovered. 200 times the mass of our sun, it goes bang but doesn't produce a black hole.
