The Dick Chambers Observatory was open for observing the 'blood moon' on the evening/morning of the 20th-21st January and for a change the weather was good. Other members observered from their homes and below are a few images by members.

Our automated meteor camera and meteor team, detected 239 meteors in December, despite the cloudy weather, 60 of these were identified as part of the Geminid meteor shower. The brightest meteor detected was a magnitude of -1.8. During December we identified meteors from 22 different showers, but the geminids was by far the strongest.

Below is a video of the meteors detected by the meteor camera operated by the society, in December 2018, the meteors are ordered by brightness based on analysis by UFO analyser.

Comet 46P Wirtanen was billed to be brighter than ever this apparition and when at its brightest it would be passing within 1 degree of M45, however the UK weather conspired against us, some members got images from outside the UK and others from before it reached its brightest, but our visit to Ashdown forest was cancelled due to 100% cloud cover and rain.

On Thursday 13th December 2018 many members observed the comet at the Dick Chambers Observatory, through binoculars (a very faint fuzzy blob only visible with averted vision) and through the 16" Peter Hindle telescope.

I've been getting some practice with deep sky stacker, not as scary as I thought here is my first attempt using it to stack some images of the comet.

Image by Honor Wheeler

I've been lucky to have imaged the comet twice myself, once on Friday 7th & again on Sunday. The seeing has been pretty poor but it was just visible in 10x50 binoculars and looked pretty good in my 72mm refractor and 40mm eyepiece.

We welcomed the Children of Sutton-at-Hone Primary school to the Dick Chambers Observatory on the 12th December 2018. They had a chance to look through the Peter Hindle telescope and from the photos it looks like they had a great time, whilst learning a bit about the science of Astronomy.

Parental permission given for all images used.

October saw us identifying 308 meteors from 32 different showers, the October Draconids and the Orionids being the most interesting.

The brightest meteor was -3.7 vMag

October Draconids Report

21 October Draconids were identified in the charts below you can see they are a very narrow peak, suggesting a narrow stream of dust the Earth is passing through. The average magnitude was 1. 2018OctDraconids

Ground map of the Draconids showing the meteors that were triangulated with the Nemetode group, our observations are the ones detected by the 'Dartford' Observatory

Orionid Report

We identified 53 Orionids, peaking on the 21st October and an average magnitude of 1

2018OctOrionids

Below is a 15 minute video of all 308 meteors verified in October.

We hosted The 2018 British Astronomical Association Back to Basics workshop on 6th October.

These workshops are great for beginners just starting out in astronomy and wanting to learn how to use their telescopes or get started in Astronomy and over 50 people turned up - well done and thank you to all the Crayford Members who helped out.

The slideshow below is of photos taken of the day by member Jim Burchell - Thank you Jim.

The society run an 'almost automated' meteor camera, if you want to be part of the meteor team checking the results every morning then please speak to the coordinator - Janice.

A total of 535 Meteors were captured, with 340 of them being Perseid meteors. Below is a video of the 20 brightest meteors during August.

2019 Calendar

[et_pb_section bb_built="1"][et_pb_row][et_pb_column type="4_4"][et_pb_text admin_label="Intro Text" _builder_version="3.12.2"]

Some of you who were present at the Pavilion on the 29th of March will be aware of the following changes to the Society’s Calendar rules. Each month will now consist of a collage of member’s images rather than just one per month.

The Calendar size will also increase from 21 x 28cm to 28 x 37cm picture size to accommodate the collage of images, I am unsure how many images can be accommodated per page but it may be between 6 to 8, actual numbers TBA. Price TBA.

Rather than the list of 4 groups such as the Moon, Sun, Deepsky etc. there will be a list of 'Targets' for member’s to photograph or sketch.

Important: Image/s to be submitted for the 2019 Calendar must have been photographed or sketched after the 1st of January 2012 but no later than 8pm (GMT) on the 3rd of October 2018.

(All images for the 2020 Calendar will need to been photographed or sketched AFTER the 3rd of October 2018 but before the 2nd of October 2019 so keep this in mind when submitting your images).

DON’T FORGET TO READ THE RULES!

PLEASE DO YOUR BEST TO TAKE PART, THANKS.

[/et_pb_text][et_pb_text _builder_version="3.12.2"]

Target images for the 2019 CMHASD Calendar are as follows:

1. Earthshine

The Moon’s shadow side can often be seen when the young crescent Moon is visible. Images must show the Moon with the shadowed side also visible

2. A Rainbow

Images can be an Arc or a portion of the Rainbow.

3. The Planets

Images can be of any of the Planets (not the Earth that would be cheating ;)

4. Lunar and/or Planetary Conjunctions

Images can be of the Moon in conjunction with Planet/s or a planetary line-up of 2 or more Planets.

5. The Orion constellation

Images that show the Orion constellation in full as the left image or as the image on the right with the four stars Betelgeuse, Bellatrix, Saiph and Rigel at each corner.

6. Lunar Eclipse

A Lunar eclipse will hopefully be visible on the 27th of July but any images photographed or sketched after the 1st of January 2012 can be submitted. The Moon partially or fully eclipsed will be acceptable.

7. Atmospheric Optics

Images of any of the following: Solar Halo, Sundogs, Circumzenithal Arc, Cloud Iridescence and Crepuscular Rays etc.

8. The Andromeda Galaxy

A close-up image of this wonderful Galaxy.

9. Sunset or Sunrise

Any photograph or sketch of a Sunrise or Sunset over land or water.

10. Lunar crater Copernicus

A close up of the crater Copernicus photographed or sketched using a Telescope or a Telephoto lens.

11. Sunspots

Images of Sunspots in White Light or a projected image only, not H-alpha (as only a few members have H-alpha telescopes).

12. Ursa Major constellation

Images of the whole constellation or the Plough will be acceptable.

13. A Full Moon

The Moon must be between 98 – 100% to qualify for this Target, you’ll need to make sure as I will check the date and the image was photographed or sketched.

14. The Pleiades and/or the Hyades

An image of either the Pleiades or the Hyades or an image of them together.

I am aware there are 14 Targets, not everyone will be able to image all of the Targets so hopefully this way everyone will be in with a sporting chance of obtaining at least one image for the Calendar.

Rules: And please make sure you read them!

You may only enter one image per category.
Sketched, Single, Multiple Stacked or Mosaicked images are acceptable, Composite images are NOT acceptable.
All images entered must have been Photographed or Sketched by the person entering the image/s.
If too many images (maximum numbers TBA) are entered for one ‘Target’ then a vote will be taken on each image and the images with the most votes will be included in the Calendar.
All images MUST have been taken AFTER the 1st of January 2012 but before 8pm (GMT) on the 3rd of October 2018.
The two ‘Targets’ with the least number of images received will not be included in the Calendar.
Images can be taken using another member’s telescope but the camera used MUST belong to the member submitting the image/s.
Poor quality images will have to be omitted so make sure the image resolution is good enough for printing.
All images MUST be submitted to this email address: honor . draconis @ talk21 .com (remove spaces) BEFORE 8pm (GMT) on the 3th of October 2018, no exceptions.

When emailing your images please use the email subject heading ‘CMHASD CAL2019’ that way I can save the images easily all in one place!

Small print - Feel free to ask me any questions that are not covered by the rules but if you do ask me a question that IS covered by the rules…then I’ll know you didn’t read them! Simon, Martin, Jim….! [this is scandalous Ed.]
