You can se a comparison spectrum at: http://www.cfa.harvard.edu/oir/Research/supernova/RecentSN.html
Ring size: 1.6" East-West 1.2" North-South (but has ~45 dgree inclination) The spot has moved 2 pixels or 0.050" in 7 years or on a different set of images I get a motion for spot #1 of 1.85 pixels @ 0.025 "/pixel = 0.046" 0.05"/1.6" = 0.03125 percent of the ring diameter Time between the 1999 and 2006 image = 2785 days =2.4e8 seconds Ring size=1.2e18cm diameter (from Nino's paper) =1.2e13 km * 0.03125 =3.75e11 km Velocity of =3.75e11 km / 2.4e8 seconds = 1562.5 km/sec The Magellan echelle spectrum I took last year @ H beta. There's emission of +/- 300 km/sec Full width @ zero or continuum level. [OIII] +/- 200 km/sec... and lots of +/- 30 km/sec emission lines from the stationary ring ??
from Peter Garnavich showing the
ring brightness versus time . time runs up and angle left-right. Did the spots (2006 top of
figure) show up in the bright regions (1994 bottom) of the ring ?? Are the Dark regions more
dense then the brigher parts ???
showing the nonspherical symmetry in the
debris H alpha=Red F625W=Green F250W=Blue
H alpha=Red [OIII]=Green F250W=Blue
HA/[OIII] 2003 = BLUE HA/[OIII] 2006 = RED If the ratio stays the same then we get white (or pink), because the left side is
reddish, that means those spots have much more Ha flux to [OIII] then in 2003 /a>

I guess this is the image that I can make thats closest in color to the previous HST release. http://hubblesite.org/newscenter/archive/releases/star/supernova/2004/09/ These are the Dec 2006 HRC observations.

WFPC and CTIO corrected mags...
The ground mags have the contribution of the ring in them.
These mags have that contribution removed.
I normalized the stars (and therefore debris) mags to the CTIO mags.
for stars.. this is probably okay. However, I didn't use any
corrections in going from HRC/F435W to B or WFPC2/F439W to B.
Corrections could be made for stars, but it doesn't make sences for
the debris (an emission line source).
