During the late evening of May 18th 2015 I was working on video editing in my room after a local chase earlier in the day when between 20.30 and 21.00 UT I felt a sudden impulse to glance out my window which revealed a stunning sunset sky show unfolding. I ran into my front garden and was instantly treated to the best mammatus cloud display I have ever seen with large udders arranged in streamers on a fanning wispy anvil all lit into glorious gold and yellow colours by the setting sun. For ten delightful minutes I watched and photographed the cell as it passed over Slieve Gallion with US-style mammatus hanging over Maghera before it passed over Lough Neagh and vanished into the darkness of dusk accompanied by several departing rumbles of thunder marking the second time a sunset mammatus display passed over my home area within a week, read the report for more information. * All images are available for sale in the form of photo prints, canvas or digital files for licensing, if you are interested in a purchase simply drop me an email.
