Well, not precisely calling a supernova, but good enough to be exciting. A massive cluster is between us and the supernova, resulting in gravitational lensing. An article in astronomy.com says:
Many stars end their lives with a with a bang, but only a few of these stellar explosions have been caught in the act. When they are, spotting them successfully has been down to pure luck — until now. On 11 December, 2015, astronomers not only imaged a supernova in action, but saw it when and where they had predicted it would be. As the matter in the cluster [bending the light] — both dark and visible — is distributed unevenly, the light creating each of these images takes a different path with a different length [and taking a different time to reach Earth].
The supernova was seen in one of the images a year ago. It implies that the watchers were able to calculate the paths the light took, and predict when the supernova would appear in another image — and got it right. So, the takeaway is that no, they weren't able to make the prediction based on the instablility of the star, but they were able to calculate gravitational effects and predict the supernova would show elsewhere this month. Isn't that enough?

And by the way, you misspelled "title". There are only 2 T's in it, not three.

Wow, just wow.
You have my eternal gratitude for informing me that not only did my finger twitch and generate a third "t" that my auto correct missed, since "tittles" is an actual word (though not suitable for the context of my comment), but also for publicly confirming that you have a long way to go before you can have any real credibility as an editor.
A good editor doesn't let comments critical of their abilities upset them to the point that they feel they have to get defensive and even lower themselves to making unprofessional and snide comments such as the one you wasted your time writing. They learn from the event and try to do better next time. If you find this too difficult I would suggest that you either develop a thicker skin or find another use of your time that does not entail exposing yourself to criticism.
I on the other hand, not being an editor, can make all the snide comments I want. The worst that will happen is people agree with me, or call me a troll, or worse. It will not be the first time, nor is it likely to be the last.
