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.

Above is an image, remotely taken with the PlaneWave 17″ robotic unit: the supernova was found at mag. 10.6, clearly brighter than 22 Jan.

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:
