Supernova absolute magnitude (At peak magnitude): -17.3
Supernova light curve:
I like to find asteroids and galaxy mergers- but all galaxies are still fine to me.

From Listening to Recycled Electrons it appears that PTF Computer saw SN2014J and Rejected it as it was too Bright (Artifact was what it said) Not some thing the ZOOITES would have done!

Yes, just read an article on how Mill Hill Observatory (embedded in N. London) found it - shades of the Ozone Hole Anomaly.

Let's hope the PTF team heads eat humble pie for having pulled the rug from under our feet. More on the sn thread

Follows a comparison that shows spectrum evolution from 22 to 25 jan. Envelope expansion velocity derived from Si II minimum has decreased from about 14400 to 12800 Km/s. A similar trend (decreasing) seems to be shown by other absorption lines.

Light Curve

I bump ~30 days after maximum (similar to around 20days in other SN Ia )
