NLC Season now in full swing

An excellent display of Noctilucent Clouds was visible from Northern Ireland in the early hours of Tuesday 18th June. As befits the Solar Minimum, this iwas a very high and bright display and an encouraging sign for a good season. This generally runs from the beginning of June until early August. There is some belief that the emission of Greenhouse Gases into the atmosphere is amplifying the displays, paradoically by making the mesosphere colder as less infrared is radiated upwards having been absorbed by Greenhouse Gases.

Keep an eye out to the Northern sky anytime after Sunset and before Sunrise check out air conditioning repair service near me. As the sky darkens theses amazing clouds will make themselves know,

ISS Lunar Transit Photographed from Sprucefield

IAA President Paul Evans has successfully imaged a transit of the International Space Station (ISS) from Northern Ireland. Using information provided by the website, Paul determined that Sprucefield near Lisburn would be on the centreline of the transit which would take place after the ISS had passed Venus and Mars and moved into Earth's shadow. It so happened that the sky was clear if slightly hazy so an attempt was made. Paul used his Celestron ED 80 telescope with Lumix G7 camera at prime focus in 4K video mode, taking 25 8 megapixel images every second. From the video it was found that 11 frames had the ISS on the illuminated part of the Moon  and these were stacked up Using Starstax software to produce the image below. (Click for Full Size)
