Transit of Mercury - A few photos of the transit and trip

Edwin Rod
 

Here are a few highlights of the trip north from Wellington to enjoy the Transit and tomorrow I'm heading up for one night for the NZ astro photography weekend

Transit of Mercury
https://sciblogs.co.nz/out-of-space/2019/11/10/how-nz-was-put-on-world-maps-using-a-transit-of-mercury

On 9 November 1769, Cook landed on the shores of the bay to observe a Transit of Mercury. In 1919, an area of land around Shakespeare Cliff was set aside, and a small memorial was constructed, based on the erroneous notion that it was the location of Cook's observations. But the actual site of Cook's landing and observation was the eastern end of Cook's Beach, near the Purangi estuary.

Hi everyone

Please find all the regular newsletters attached, along with starcharts and a look at Titan.

Wellington finally had a Summers day today! There have been a lot of cold South westerly winds over September and October this year, The air has bene very hazy today and we need to thank our friends over the Tasman for their dust and smoke, I’ve attached a satellite photo to show Its not just my imagination.  

Well it sure has been a busy month this one. We were lucky enough to do a week’s trip away to aptly named Mercury bay to watch this month’s Transit of the Planet, I have managed to place a few cellphone photos up from the trip, however this month has been rather busy on the personal front so I have not yet had a chance to look at the Nikon P900 or do a full write up on the Transit and send out photos so watch your inbox for another email on that subject.  

We have two interesting updates from Andrew B, UK Kent this month to share. He takes a look at Asteroid 162173 Ryugu (1999 JU3), an interesting mission I have been following. KBO 486958 Arrokoth now has a name and this is an interesting object, Andrew again brings us up to speed.

 

There was no shortage of interesting stories this month and research out.

The hunt continues for an outer Ice giant world, and this month the team found a pair of Brown Dwarfs around 70Ly away an interesting discovery if like myself you’re interested in these objects.

Panspermia again has a look in with research at exporting life out of the solar system.

If you’re interested in exo moons, Red Dwarfs and life on other planets then there are a range of links this month to follow up on.

Anyway its get late here so I better let you read through what interested you from this month.

Cheers Edwin

The trip has been amazing thanks to our hosts. Its overcast now for the star party, and not sure for the Transit in the morning.

October 2019 Newsletters and Starcharts

Edwin Rod
 

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
