Okay well evidence and reference now indicates the event was witnessed on earth south Hemi in 1271ad, in Japan but then if it is actually 800 ly away, the actual event happened in 471 ad....and took 800 years to reach earth at light speed . And so the full shock wave has past earth already and we are thus seeing perhaps shadows or echoes of it travelling slower than full light speed.

How long does the wikify tag have to stay on? It is a short article. The references say an awful lot about this supernova remnant, but the most important facts are that it is the closest, it is invisible, and no notes of it remain. I don't think the article needs to be any bigger or more referenced. I think it is time to remove the wikify tag. -- 67.81.119.3 03:16, 7 August 2007 (UTC)-- Marcwiki9 15:41, 7 August 2007 (UTC)
Original version said that the supernova was 700 years ago and 700 light years away; I tried to clarify this a bit to say it occurred 1400 years ago and would have been seen 700 years ago. Also, I change the distance to 650-700 light years, since the references give both figures. Geoffrey.landis 20:14, 8 August 2007 (UTC)
"If the remnant is indeed young and nearby, its corresponding supernova should have been visible from the Earth in about the year 1250. One difficulty with this interpretation is that there are no contemporary written reports of any supernova at that time or in that part of the sky."
Since the constellation Vela is in the southern sky, would it even have been visible in Europe and China? AndroidCat ( talk) 04:18, 13 September 2011 (UTC)

Well if this vela jr micro nova ? Remenant is 800 Ly away and exploded 800 years ago...??? Then it wouldnt be visible to earth, till around now...1320 ad +800 years 2120 ,ad Much as a telescope sees an approaching asteroid. The Hubble telescope captured the approaching shock wave that follows the light , in 2004. Not sure how far away the wave was ?????? Swanny.

Well reports I've read that the data is contradictory, and the vela jr remenant and the vela Jr claw are some how incompatible or inconsistent.. although new info on micro novas might add some missing pieces? 68.148.80.176 ( talk) 12:06, 26 April 2022 (UTC)
