Last week South Next week

Best time and the azimuth, altitude (A,h) are at lat. 35 deg in the Northern Hemisphere. Azimuth indicates 0 for south, 90 for west, 180 for north, 270 for east.

C/2025 K1 ( ATLAS ) It is expected to brighten up to 7.5 mag in October. Now it is 12.7 mag (July 24, Osamu Miyazaki). Brightening rapidly. It will be getting lower gradually after this, and it will be unobservable in September in the Northern Hemisphere, or in October in the Southern Hemisphere. But it will be observable again in August in the Southern Hemisphere, or in October in the Northern Hemisphere. It is not observable for a month around the perihelion passage. But in the Northern Hemisphere, it stays observable in good condition until mid September and after late October. In the Southern Hemisphere, it is observable only before the perihelion passage.
