Galactic Nova ASASSN-17hx is still rising – 21 July 2017
After one week from our previous observation, we looked for the galactic nova ASASSN-17hx again, finding it brighter, at least on CCD images! This objects continues to shines for most of the night, waiting for you observing it.
The image above is the average of five, 30-seconds exposures, unfiltered, remotely taken with “Elena” (PlaneWave 17″+Paramount ME+SBIG STL-6303E) robotic unit available at Virtual Telescope. The image scale is 1.2″/pixel.
Doing photometric analysis on some of our images, we measured a magnitude of 9.7 (unfiltered, R-mags for the reference stars from UCAC-4), which means the star brightened a few tens of magnitude in a week. In one month from its discovery, it gained two full magnitudes in CCD images. Accordingly to the AAVSO , visually it still shines around mag. 10.4/10.5, accessible with very small instruments.
