The latest ExoClock observations by Simon Dawes
Three more sets of observations of exoplanet transits for the ExoClock project by Simon Dawes. WASP-52b, Qatar-1b and HAT-P-6b.
WASP-52 b is a gas giant exoplanet that orbits a K-type star. Its mass is 0.46 Jupiters. Exoplanet WASP-52b orbits at a distance of 4.07 million km from its host star WASP-52, taking 1.75 days to go round its orbit. Its discovery in the constellation Pegasus was announced in 2012.
Qatar-1 b is a gas giant exoplanet that orbits a metal-rich K-dwarf star, which is one of the faintest around which a planet has been discovered by ground based surveys. Its mass is 1.294 Jupiters, takes 1.4 days to complete one orbit of its star and is 0.02332 AU from its star. Its discovery was announced in 2010.
HAT-P-6b was discovered on October 15, 2007. It is located in the constellation Andromeda. It takes 92 hours, 28 minutes, 17 seconds and 9 deciseconds to orbit its host star. The planet HAT-P-6b is named Nachtwacht. The name was selected in the NameExoWorlds campaign by the Netherlands, during the 100th anniversary of the IAU, after Rembrandt's painting The Night Watch. It is one of the few planets that is in a retrograde orbit around its host star.
New music video & stunning image by Neil Webster
Member Neil Webster has been busy and produced this wonderful image of NGC 6823 & SH-2-86 in the constellation Vulpecula plus a new music video.
SH-2-86 is an H Alpha emitting region (red glow) from the Sharpless Catalogue and NGC 6823 is a small open cluster just above the central dark spike in the image.
Published by Stewart Sharpless in 1959, the SH2 catalogue lists 312 emission nebulae, planetary nebulae and supernova remnants visible in the northern hemisphere. Despite overlapping with deep-sky objects in the Messier and NGC catalogs that are visible to the unaided eye, SH2 is primarily composed of obscure, dim nebulae which can only be revealed through astrophotography.
Neil acquired the image on the 2nd October 2022 using a AA 115mm APO, EQ6-R, ZWO ASI294MC Pro, L EnHance filter, Orion 50mm Guide Scope, ZWO ASI290MM
90 x 140s Lights, 15 x Darks, 30 x Flats/Bias.

Then sit back and relax and take a tour of the Jellyfish Nebula (IC 443) in the constellation Gemini imaged by Neil whilst listening to a piano based soundtrack. To do so click on the following link The Jellyfish Nebula IC 443 - YouTube where you find Neil's latest music video.
Congratulations to members Martin Crow & Simon Dawes
On Friday 30th September 2022 at the ExoClock 2 day meeting held at University College London, CMHASD trustees Martin Crow & Simon Dawes were awarded certificates for their impressive contribution to the ExoClock Project.
ExoClock is a project to monitor the ephemerides of transiting exoplanets by the ARIEL Ephemerides Working Group.
ARIEL is a space telescope (Atmospheric Remote‐sensing Infrared Exoplanet Large‐survey mission) that was selected by ESA as part of its Cosmic Vision plan and is ESA'S next science mission that will focus on the nature of planets orbiting stars in other systems. It will be ESA's fourth medium-class science mission to be launched in 2029.
Both Simon and Martin have contributed over 50 exoplanet observations each to ExoClock and more are yet to come.
Their certificates were presented to them by Anastasia Kokori, Coordinator of the ExoClock project & Professor Giovanna Tinetti, Principal Investigator of the Ariel mission.
Congratulations Martin & Simon. Well done!
Martin Crow receiving his certificate.

Exo Planet HAT-P-29b observations by Simon Dawes – Sept 2022
One more for the ExoClock Project by Simon Dawes of HAT-P-29b also known as Surt. Surt is the ruler of Muspelheim and the fire giants there in Norse mythology. At Ragnarok, the end of the world, he will lead the attack on our world and destroy it in flames.
