Sirius will not be visible any more from northern and central Europe, and in 14000 its declination will be -67° and thus it will be circumpolar throughout South Africa and in most parts of Australia.
Sirius can even be observed in daylight with the naked eye under the right conditions. Ideally, the sky should be very clear, with the observer at a high altitude, the star passing overhead, and the Sun low down on the horizon.[85] These observing conditions are more easily met in the southern hemisphere, due to the southerly declination of Sirius.
