I managed to get an early morning view of the new nova in the constellation Sagittarius this morning, March 29, 2015. According to recent observations, this unusual nova has had an unusual magnitude shift, up and down and now back up again. Grab a blanket and head out to see this bright nova before it is gone!

Nova Sagittarii 2015 No. 2 was discovered by nova hunter John Seach of Chatsworth Island, NSW, Australia.

You can consult the chart above to find the nova’s location.

Sagittarius is low on the southern horizon from my viewing location, just above tree level, but I did manage to capture it this morning. The nova is the brightest object inside the yellow circle. I used a Canon 6D, Canon 100mm f/2.8L lens mounted on a tripod with no guiding. I placed some reference star magnitudes on the chart for you.

Based on my photographic observation this morning, I would estimate the magnitude to be approximately 5.6. This was estimated by comparing neighboring star brightness’s to the nova.

Observation point was located at 40.9740663,-75.7677017 (you can paste these coordinates in Google to see where the photo was taken from).
