SN 2014J

On 23.01.2014 a supernova explosion of type Ia was discovered in the galaxy M 82. The animation shows a re-evaluation of the data of the NASA Micro-Observatory network, collected between 15. - 23.01.2014, by the working group of Oldenburg. The increase in brightness within days can clearly be seen (animation starts by click, second image: light curve of the AAVSO). More information about the outstanding importance of this supernova can be found here. 

The analyses done by the working group of Oldenburg are available at the website of the AAVSO. The collected data is part of the worldwide earliest recorded brightness values.
