Bright supernova SN 2014J in Messier 82: new image and spectrum (27 Jan. 2014)
The Virtual Telescope visited Messier 82 and its supernova SN 2014J again on 27 Jan. 2014 to check its brightness and see if – as expected – the star was increasing its luminosity.
At the same time, a new series of spectra were taken with the Celestron C14 robotic unit, equipped with a 100 lines/mm grating, with a dispersion of 34.7 “/pixel. The result is below and, as on 22 Jan., the blue-shifted Si II absorption feature is very apparent:
Here it is the resulting plot, made with RSpec:
