| Description |
The researches of morphological features of the inner coma of comet 81P/Wild 2, based on the observations on 27–28 March 2010 were carried out. Images that were obtained with the help of narrow-band filters in the main cometary emissions have no peculiarities. Two jets were located by means of digital filtering at frames in white light: the south, with the width of 20°, and north, with the width of 80°. The conclusion about the location of the narrow jet near the rotation pole of the nucleus was made from a comparison of the locations of the jets for different dates. A similar pattern of location of jets was observed during the previous comet appearances. This can be evidence long-life active regions on the surface of the cometary nucleus.
