Sorry to say, it is not a picture of a comet. Its a picture of the Sun and the camera processors "screaming for mercy" because of taking direct photographs of the Sun. You are overloading the processors.
If you continue to take direct photos of the Sun you camera will fail.
Suggest you invest into a moderately priced telescope with Sun filters which contain a small computer in which you enter Elenin's sky coordinates. Then find yourself a nice dark hill, a steady tripod, with a sky coordiante software and you will see Elenin and more.
Happy Star Gazing
