The nova star in Sagittarius has re-brightened. I captured it in a telephoto closeup.

Here is Nova Sagittarii – likely an exploding white dwarf star – as it appeared before dawn on the morning of March 28. This is the brightest nova visible from the northern hemisphere for many years, though even now it is barely naked eye at fifth magnitude.

After dimming for a few days the nova has re-brightened somewhat. What titanic forces are going on at this white dwarf star causing it to fade then brighten remain to be determined.

It will certainly be worth keeping an eye on. With luck it might really get bright!

This telephoto image frames the “Teapot” configuration of stars that forms the main part of Sagittarius the Archer. The nova has appeared from out of nowhere in the middle of the Teapot just below the lid!

The image is a stack of 4 x 90-second exposures, plus an exposure taken through a Kenko Softon A filter to add the star glows, to accentuate the brighter stars. I shot this from the backyard in New Mexico.
