Martin Crow – Exo Planets WASP-58b, TOI-2076b & HAT-P-57b

The latest Exo planet observations by Martin Crow for the ExoClock project.

TOI-2076 b is an extrasolar planet (exoplanet) that orbits a K-type star TOI -2076 in the constellation of Bootes. An exoplanet is a planet that orbits a star other than the Sun. The star is located 136.86 light years away from Earth. TOI-2076 b is a Neptune-like exoplanet, its mass is 6.89 Earths, it takes 10.4 days to complete one orbit of its star and was discovered in 2021.

 

WASP-58b was discovered in 2011 and has an orbital period of 5 days.

 

HAT-P-57 b is a gas giant exoplanet that orbits an F-type star. Its mass is 1.41 Jupiters and it takes 2.46 days to complete one orbit of its star in the constellation of Aquila. Its discovery was announced in 2015.

Simon Dawes – Exo Planet TOI-1296b

One more for the ExoClock project by Simon Dawes. Exoplanet TOI-1296b.

TOI-1296b was discovered in 2021 and observed with TESS and SOPHIE.  It is a hot Saturn-mass exoplanet with an orbital period of 3.944 days.

Simon said 'Got this Friday night; 7 milli mag dip on a mag 11.5 star - quite a noisy measurement due to twilight observation.'

 

Informal Night & UFO – 21st April 2022

Thursday 21st April 2022 was an informal night at the pavilion and some members took the opportunity to do some observing with some members viewing a very rare sight indeed.

Chairman John Archer summed the evening up in his ebulletin to members dated 27th April 2022. He wrote 'Last week we had another opportunity to get together for an observing evening and a variety of instruments were rolled out – everything from EV Scope and iPhone to Mark 1 eyeball was scanning the night sky.

Members sought out the elusive planet Mercury, and once skies darkened, other more distant objects could be seen.

A flurry of excitement and speculation surrounded the appearance of a mysterious, moving object in the night sky which turned out to be a SpaceX Falcon upper stage conducting a de-orbit burn prior to re-configuring itself into a marine reef / insurance claim – depending on where it finally landed.''

Some objects were also observed using the societies 16" Peter Hindle telescope they were M81, M82, M44 and the Eskimo Nebula.

Below are some images from the evening taken by member Jim Burchell.

Mercury in the constellation Aries just before sunset taken using a Pentax KP 135mm F11.0, Exp 1/2sec &  ISO 800.

The Observatory taken using a Pentax KP 18mm F3.5, Exp 10sec & ISO 800.

Constellation Leo taken using  Pentax KP 48mm F7.1, Exp 2.50sec & ISO 800.

 

The next 2 images below are snapshots taken from a video that member Steve Goldson managed to capture of the UFO that four other CMHASD members witnessed too at 8.46pm.  The 1st photo shows what looks like a small cloud moving very quickly through the sky.  The 2nd photo shows the same unidentified object a few seconds later now as a bright dot with a cloud in front of it moving through the sky.

 

The members were perplexed but excited by what they had seen with most sighting it as their 1st UFO.  Later after some detective work by Honor & Sonia it was concluded that they along with Jim Burchell, David Freed and Steve Goldson had witnessed the second stage deorbit of SpaceX Falcon 9 after launching another batch of Starlink internet satellites (Starlink 4-14).

The Moon by Neil Webster – 5th & 7th May 2022

These two superb images of the Moon were captured by member Neil Webster on the 5th & 7th May 2022. 

Neil acquired the images using and Altair Astro 115mm triplet APO, EQ6 R mount, ZWO ASI290MM camera plus Astronomik R/IR filter.

Each image consists of 3 frames stitched: each 90s x 33fps....20% selected, aligned, stacked in AutoStakkert3 and processed in PS.

The Moon - 5th May 2022 - Waxing Crescent 19% and 4.23 days old.

The Moon - Moon 7th May - Waxing Crescent 36% and 6.02 days old.

Exoplanet KELT-23Ab by Simon Dawes

Another set of observations by Simon for the ExoClock project.  

KELT-23Ab was discovered using the Kilodegree Extremely Little Telescope (KELT). 

The Sun – 8th & 9th May 2022 by Simon Dawes

Two more great images of our Sun on the 8th & 9th May 2022 by Simon Dawes and now up to Sunspot number AR3007.  

Sunspot AR3006 however is behaving a bit odd as described on Spaceweather.com  ''A MIXED-UP SUNSPOT: Sunspot AR3006 is having an identity crisis. It is supposed to have a +/- magnetic field. Mostly it does. But deep inside the sunspot's primary core, the polarity is opposite: -/+................The mixture of magnetic polarities makes this sunspot interesting and dangerous. When opposite polarities bump together, it can light the fuse of magnetic reconnection--the explosive power source of solar flares. If AR3006 flares today, it will be geoeffective. The sunspot is directly facing Earth.''

Type 1a Supernova SN2022hrs in NGC 4647

An awesome capture by Simon Dawes of a Supernova called SN2022hrs in NGC 4647.

NGC 4647 is an intermediate spiral galaxy in the constellation Virgo.  Supernova SN2022hrs was discovered in the galaxy NGC4647 on the 16th April 2022 by astronomer Koichi Itagaki.  NGC 4647 is 63 million light years away, so, this star exploded 63 million years ago and it took that long for the light of the explosion to reach us.

Messier 60 (NGC 4649), an elliptical galaxy, is also in the image and it is in the centre of the frame and NGC 4647 is slightly down and to the right of it.  SN2022hrs looks like a bright star in front of the galaxy but it is actually an exploding star within the galaxy.
