The season of noctilucent clouds is open! Bright noctilucent clouds were observed over Minsk (Belarus) during all the night 01.06-02.06.

Comet C/2014 Q2 (Lovejoy) just at its maximum approaching to Polaris star separated by 1 deg, imaged on May 29, 2015. Its brightness has dropped until 8th magnitude, meanwhile coma has lost intensity in its green tone. The image no reveals the everytime more faint ionic tail, surely because was taken from a suburban sky; nevertheless seems show something of dust tail toward northeast.

They looked so close! Both pots of gold should be right there for the taking. Unfortunately, there's the quicksand to consider as well...
On the foreground, one can see the shadow of the Mont's iconic shape.

Fireball Magic II by Marsha Kirschbaum, on Flickr

My camera was exposing with an intervolmeter for star trails, when this amazing fireball streaked towards the earth. It light up the ground for an instant like daylight. 12 other late night persons also saw and reported this fireball to the American Meteor Society.
