About this image

I took some pre-dawn images of this nova via T11 at New Mexico (0.51m CDK).

This is the 'pretty pic' unfiltered 120 sec image.

I also took some much shorter V filtered images. The brightest pixels in the nova disc were 30% of the way to saturation in a 5 second V shot.

Using the AAVSO chart's somewhat dimmer mag 9.0 and 9.1 stars gives a V mag of 7.70 at 11:45 UT this morning (Mar 20). JD = 2459293.98958.
