Noctilucent clouds and lightning show
Credits: Adrien Mauduit
High Level's latitude gives the Project Possum team (Citizen science research program) and myself an excellent vantage point to capture not only the elusive noctilucent clouds, but also other great natural phenomena like the aurorae or thunderstorms. This 3-shot panorama was taken three nights ago back at the PoSSUM den, as the flight team was recording NLC's above a thunderstorm. You cannot see the plane, but you can definitely see lightning, which gives another dramatic dimension to the shot. The electric-blue filaments contrast very well with the beautiful gradient of the never-ending sunset! It was surely a moment I am not going to forget anytime soon!

Structure of clouds at the edge of space
Credits: Adrien Mauduit
As the PoSSUM noctilucent cloud airborne campaign (NASA-funded) unfolds in High Level, Alberta, Canada, the PoSSUM team gets valuable scientific data using PMC-turbo cameras. As part of the science communication and outreach effort, I'm helping the project by taking ground imagery. It includes still images that reveal the structure and evolution of the clouds in a breath-taking fashion.
You might think they look like the waves of the ocean or the bottom of a pool, and that's exactly what this wondrous natural spectacle looks like. This ice particles reflect the light from the sun as they are sandwiched by different layers of the upper mesosphere. this, in turn, allows the delicate and elusive fluid mechanics to be witnessed and understood better, hence the goal of the project. In this shot, waves, billows, knots, bands, lacunous holes and veritable storms are waiting for you!
Panorama of 16 shots at 500mm taken with Canon 6D and Sigma 150-500mm APO, July 4th 2017 in High Level, Alberta, Canada.

Noctilucent cloud arc under big dipper and Cassiopea
Credits: Adrien Mauduit
We witnessed the widest and widest NLC display so far in High Level, AB, Canada on July 1st, 2017, on the PoSSUM NLC airborne research campaign. The show surprised us at around 1:10 am, whereas it was clouded and the rain just let up! I went out on the deck to look if by any chance it had cleared. And it had! I alerted everyone that NLC were starting to show in a very impressive manner behind tropospheric clouds. The team managed to get the PMC turbo cams out and collect valuable data. At 2:30 am, the display peaked and we witnessed an extra arc, barely illuminated that stretched from west to east (180 degrees) and all the way up to above our heads! (We even thought it was aurora at first!). I have seen structures (pictures to come soon) that I had never seen before and we were so excited!
Look at how the arc draws, almost like a rainbow across the sky, right under the big dipper and Cassiopea!

Noctilucent cloud photobombed by aurora borealis
Credits: Adrien Mauduit
On July 1st 2017, The PoSSUM team and myself were doing research on NLC in High Level, AB, Canada, when the northern light suddenly photobombed the NLC in an extraordinary manner. The pillars advanced behind of the clouds, and it was a magical moment. You can definitely see that they occur at a higher altitude, but as whether they have an impact on the NLC down below (transfer of energy) remains a mystery to be solved!

Jupiter Occultation (2012)

Almost 5 years ago (on July 15, 2012) the Moon occulted Jupiter. From near to far I was able to capture some low clouds, the Waning Crescent Moon, two Jovian satellites (Io and Europa) plus the disc of planet Jupiter appearing from behind the ashen limb of the Moon and some background stars of the constellation Taurus.
And the reflection of the Moon and Jupiter in the water of a typical Dutch landscape:

M51 and NGC 5198
Here is a 2 pane mosaic of M51 and rarely imaged NGC 5198 which is Located south of the Whirlpool Galaxy in the sky. We all know about the wonderful whirlpool galaxy but here is a new view of it with its close friend, NGC 5198 is a seemingly ordinary elliptical galaxy that was discovered in 1787 by William Herschel. Deep images however reveal a recently discovered tidal tail in addition to an outer tidal shell. The length of the tidal tail is approximately 300,000 light years and is the remains of a small galaxy that has been absorbed by NGC 5198. The linear nature of the tidal tail is indicative of a recent collision with a previous companion or satellite galaxy, which has been tidally disrupted by the larger galaxy."
