Galactic Nova ASASSN-17hx does not stop rising: new evident brightening – 24 July 2017
You might be used to hear this, but we are happy to say it again: the galactic nova ASASSN-17hx is still rising, now shining at mag. 8.8 on our CCD images! So, we were right, last time, to bet on this. Really, now you cannot miss it: go out there and see this exploding star with very simple equipment.
The image above is the average of five, 15-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. The object is marked with two red lines, in the center. Seeing was not good, this is why the stars ar not as sharp as usual.
We have seen this star continuously rising in brightness, since it was discovered, on 19 June 2017. Tonight, as we expected, we have found ASASSN-17hx at mag. 8.8 (unfiltered, R-mags for the reference stars from UCAC-4), so 0.6 magnitudes more than 48 hours earlier, quite a remarkable increase! It was already visible with small equipment, but now it would be a shame not to have a look, as you need very basic equipment, like your finderscope. Visually, it should be around mag. 9.2/9.5 and we made some useful star charts to find this nova: now, it is up to you!
