Last February, comet C / 2011 L4 (PANSTARRS) showed itself, as it approached the Sun, as an extremely dusty comet, which developed a powerful tail. Until March 10 (the day of its perihelion) it continued to approach Sol, and now that it is coming back, starting its way back, it can also be observed from the northern hemisphere, including Spain. For this the first days you will need optical (binoculars) or photographic help and of course a horizon free of obstacles and a transparent sky.
As the days go by, the PANSTARRS will be a little higher at dusk. March 13 will be especially significant in March, the comet will be seen at sunset on the western horizon under a thin crescent moon, barely "one day old," according to experts. During the following days the PANSTARRS will ascend between the constellation of Pisces and the square of Pegasus and it should already be possible to see it with the naked eye, although the Moon will shine more and more, making it difficult to see.
From March 22, the comet will enter the constellation of Andromeda and can be observed until almost the beginning of the astronomical night. Finally, as of March 29, it will again become clearly visible without the bother of moonlight as it approaches the Andromeda galaxy, a photogenic encounter that will take place in the first days of April.
