Is the sky worth a look tonight
Tonight's verdict for a Polish city: worth it, maybe or not, and why; the dark hours and the clearest stretch, MET Norway's cloud cover hour by hour, the moon's phase and whether it is up, a visible ISS pass, the chance of the aurora, the planets up and a meteor shower near its maximum. Warsaw when no place is given.

Northern lights in Poland
Whether the aurora can be seen in Poland tonight, from NOAA's Kp index: the level (none, only on a photo, to the naked eye low in the north, high in the sky) in the north, centre and south of Poland or in a given city, the Kp each needs, Kp now and the forecast for the next days.

Meteor showers
The twelve main meteor showers seen from Poland for the next twelve months: activity, maximum (Polish time), ZHR, the best hours on the night of the maximum and whether the moon gets in the way. With a shower (e.g. perseids, geminids, Leonidy) only that one, and for the six main ones its night in each of the 18 cities.

near_earth_objects
Asteroids and comets passing Earth
The asteroids and comets passing Earth between two dates (seven days at most; today and the next six by default), from NASA's NeoWs: when each comes closest (Polish time), how far (km and lunar distances), how fast, how big, and whether NASA classes it as potentially hazardous, the closest first.
