HAT-P-30b is a transiting hot Jupiter around a 1.25 solar mass star in the constellation of Hydra near the boarder of cancer.

Martin Crow and Simon Dawes observed this exo-planet transiting its parent start part of the exoclock project, to refine transit predictions for the Aerial space craft wich will be observing exoplanet transits to learn more about these enigmatic planets.

We have had some lovely clear and moonless nights the last couple of days and on top of this few contrails from planes making the sky ideal for observing, and whilst alone with your telescope or binoculars you can still share your experiences using our WhatsApp groups, just contact committee@crayfordmanorastro.com if you want to be added...

Here is a selection of member observations shared over the last few nights.

You may already know this but it’s always worth looking from the edge of Mare Crisium to the limb of the moon. Due to libration you will see that this changes and sometimes we can see a little further around the moon.[/caption]

Recently Mr Martin Crow, gave a talk entitled "A brief introduction to Astronomy" (The edges of the Jigsaw) for some of the societies new members, to help them better understand the "Jigsaw that is astronomy".

Martin spoke amongst other things about.

·        Measuring astronomical distance by using astronomical units (au) & light years,

·        The spectrum of stars to determine their chemical components,

·        Looking at objects with different parts of the electromagnetic spectrum i.e. infrared, white & Ultra- violet light.
