Nova in Canis Major, 2018

Calibrated color image from Sloan i' r' g' filters, calibrated using APASS magnitudes of field stars.

The star is in the very center and appears reddish.

North is up in this cropped view.

No processing other than levels in Photoshop.

On March 31 at 10:00 UT I measure the Sloan magnitudes to be:

i' = 10.35, r' = 10.80, g' = 11.79 g'-r' = 0.94

Using the Jordi 2006 conversion formula, this maps to:

B = 12.30, V=11.24, R=10.72 B-V = 1.06
