Noctilucent Clouds seaon once again
For around 4 weeks either side of June 21st in the Northern Hemisphere tat latitudes between 50° and 70° here is a chance to spot a naked eye phenomenon termed "Noctilucent Clouds", which literally means night shining clouds. NLC's (for short) are clouds form so high up in the polar mesospheric clouds in the upper atmosphere that it is thought they exist as water-covered meteor dust. Well after evening twillight looking at where the sun has set (or going to rise) with no clouds and you might spot the silvery-blue display - you'll know if you see them!
You can read more from any of the previous threads showcasing previous displays here.

Our first ever calendar shifted many of copies since it went on sale back in November. Now (minus the 12 monthly winning photos), you can download it from the forums here >
It is only because of the trojen work of the team behind the compilation and selling of the calendar that IFAS has been able to purchase IFAS Eclipse Shades in time for the March 20th eclipse! So, Thank You to everyone who helped IFAS in making this milestone possible!
Remember, IFAS is the LARGEST astronomy portal in Ireland with thousands of partcipants and made possible with the work of the volunteers behind it.
