October 2019 Newsletters and Starcharts

Hi everyone

 

All the usual Star charts and news items are attached for this month. I have also attached two bit of interesting research. The first looks at Ceres and how its domes are formed, these are fascinating features that hint at an active geology and there are similarities with Earth here too.  Gale crater also gets a look at with the history of salty water in the basin and past environmental conditions.

Two stories I have been following with interest are comet Borisov the latest interstellar visitor and also the work to get the Mole working on insight. Thanks to Andrew B we have some very good updates and details that he has written up on the subjects, these can be found in the attached newsletter txt.file. Having Red dwarfs as one of my favourite subjects at the moment it was interesting reading about the star system this comet originated from.

 

Social Media

I have been thinking about how and where I contribute here, with the recent demise of Google Plus and now Yahoo Groups, places I found to be very positive and friendly platforms have disappeared. The overall feeling from these platforms from a range of people in different groups is a strong dislike of facebook in fact many refuse to use it at all. I have been spending time at Groups.io over the past few weeks and I personally like the look and feel of the place, so if you haven’t already take a look and join my astronomy group there if you like.

Neptune, Oct 21 R+IR From Antony

Edwin Rod
 



Hi everyone, reasonable seeing for a while last night made it possible
to capture some data on Neptune spanning just under an hour, and showing
some features in motion. Attached is both the single combined image
(combining nearly an hours worth of data) and also an animation blinking
the first and last images from the set to show movement. The images are
false-coloured to highlight the brighter features, a lot of image
enhancement has been applied so these may in reality be quite faint and
low contrast.

There seems to be a feature up in the northern hemisphere close to the
limb that is clear to see moving over this elapsed time, and also
something in the southern hemisphere close to the south pole but it's
not well defined.

Note the orientation is different between the two images - the WinJupos
combined image has rotation axis vertical, where as the animation is
made from raw data and preserves the original rotation axis, please
refer to insets for each.

In all cases Triton has been included for reference.

Animation:

regards, Anthony

I have started the transfer of the old Yahoo groups to the New Groups @.io

I'm not sure when and how well it will work but hopefully all the old messages and posts can be brought accross
