Re: Mercury and Venus.

David Baines
 

Hi All,

I hope everyone is keeping well. I followed Peter's advice and went out this evening to see if I could spot Mercury.I managed to find it using binoculars at first then as the sky darkened I was able to see it with the naked eye. My wife had just gone to bed but I persuaded her to come out into the back garden to have a look and she had no problems spotting Mercury once I had given rough directions.

All the best,

David

Hope you are keeping well and enjoying some decent dark skies albeit short at this time of year.

Comet SWAN should be appearing low in the NE dawn sky so I may be tempted to arise early.


A reminder to members.

If you have never seen Mercury the next few evenings present an excellent opportunity to spot this elusive innermost planet as it has a close conjunction with Venus in the W to NW evening twilight.

This evening (19th) Mercury will be about 5 degrees below Venus.
The separation will be about 1 1/2 degrees on 21st and 22nd so both planets will appear it the same field of view using binoculars or low power on a  telescope.
Using higher magnification on a telescope note the different phases of the two planets. Ask yourself why.

Reasonable weather forecast except for the 22nd.

Happy viewing and imaging!

Peter.

Thought I'd better get a quick image in before Venus sets behind my trees and the weather looks poor for the next few days.

Very hazy skies I'm afraid.

Hello  everyone,

I have put my Space News for April up on the website.

So choose which you prefer.

Alternatively, if you're really bored and would like to look up all the original webpages and details, I can email you a file with all the links that I collected over the month...  Let me know if so.

I'm working on it.

BAA Newsletter Issue 38 - Webinars and CfDS updates

BAA Webinars a big success


Link to Webinars on YouTube

Whilst we continue in lockdown, it has been gratifying to see the increased use of the BAA website and BAA YouTube site.  The number of members and also non-members signing in for our webinars has been excellent for each event, and there's no hassle with public transport!  Andy Wilson has posted on the Community Forum this message:
"The best way to keep appraised of upcoming webinars is to look at the bottom left of the BAA homepage, where the next 4 meetings/webinars are listed. There is also a full list of meetings and webinars on the BAA meetings/events page." Simple.

https://britastro.org/meetings

We would rather not send out bulk emails notifying people indivdiually as this can cause difficulties with our website provider and many members do not appreciate it.  Upcoming webinars are posted in the bottom section of this Newsletter, but they do change frequently, more often than a monthly Newsletter can advise.  It is truly gratifying the number of people who have come forward to create these webinar presentations.  Keep them coming.

News of the Binary Black Hole, OJ287

Gary Poyner reports some exciting news, "Point your telescope to a small patch of sky 3.5 degrees east of the open cluster M44 (The Beehive Cluster) in Cancer, and you will come across one of the most amazing objects visible in the entire sky – the binary black hole OJ287".

This is a really excellent time to observe this phenomenon.  Both professional and amateur visual and ccd observers have been monitoring it for several decades now and with almost 40 years of data the times of impact can be predicted with some certainty, and in July 2019 time on the Spitzer Space Telescope was obtained with successful results.  Gary says, "The results of the Spitzer observing run have now been published, and are available to download from Cornell University arXiv webpages… Spitzer Observations of the Predicted Eddington Flare from Blazar OJ 287. Laine et al 

The BBC is also running an article on Spitzer and OJ287 on its ‘Science & Environment’ news page

Finder charts for OJ287 can be downloaded from the BAAVSS web page

Good luck!


 News and Updates


Historical Section Newsletter and others.

The Spring Historical Section Newsletter has just been published, focusing on the BAA's year of 'Highlighting Women in Astronomy'.  There's a lovely piece by Bill Barton commemorating the 100th anniversary of the death of Fiammetta Wilson, who was, amongst other things, a co-director of the BAA Meteor section.  Also, note a special plea for any information on Elizabeth (Betty) Marion Davis by David Sellers who is researching an article about her for SHA News.

The Lunar, and Solar Section monthly newsletters are also now available.  The 2018 Newsletter of the Deep Sky Section has also recently been posted under publications on the BAA Website.

Commission for Dark Skies

It is good to see that the Commission for Dark Skies has just released an updated version of its advice on light pollution - Blinded by the Light.  It's a truly informative document for all those who enjoy the natural world, not just astronomers.  In the northern hemisphere we are enjoying a wonderful spring without the usual volume of vapour trails and other pollutants in our environments; it is a pity that local Councils are still lighting up our streets for nobody!  Still at least it assists night-time burglars...
Do take a look-see and spread the message.
 

Diary Dates

Please check the Events page on the BAA Website for all changes and updates to BAA meetings and other events in the light of the COVD-19 precautions.  https://britastro.org/meetings  Please also be reminded that the BAA Office is still working remotely and unable to process sales.

Next Webinars:

6th May 2020 1900-2000 - From Kitchens to Comets - Hunting for molecules with a spectroscope - Webinar.  Hugh Allen, Chairman of the Wells & Mendip Astronomers

13th May 2020 1900 -2000 - Sir Patrick Moore - Early Life, Mentors and Notebooks (Part II) - Webinar.  Dr. John Mason

20th May 2020 1900 - 2000 - The Solar Cycle - Webinar.  Solar Section Director Lyn Smith.

27th May 2020 BAA Meeting and George Alcock Memorial Lecture.  Plans are afoot to hold a webinar instead of an attended meeting as it is unlikely we will be let loose on the public again by this date.  The agenda is currently subject to change and the George Alcock lecture itself will be postponed.  Please keep an eye on the BAA Events and Meetings pages for updates on this one. 

Gentle reminder: Nominations for the Ballot for the BAA Council and Board of Trustees.  Closing date Sunday 10th May 2020.  See the  BAA Website for details.

CAA talk on The Hertzsprung-Russell diagram

Adrian Rawlings
 

Cambridge Astronomy Association are putting on a lecture using ZOOM this coming Monday 4th May, 7:15pm.

The Hertzsprung-Russell diagram

The HR diagram has been in use for over a hundred years and is an important graphical tool that astronomers use to classify stars according to their luminosity, spectral type, color, temperature and evolutionary stage. But it's much much more than a series of dots on a graph and has helped unlock many secrets of the life of stars.

Lyrids

Sheridan Williams
 

Friends from Pembrokeshire saw several Lyrids last night, they were very impressed.

Peak on Wednesday morning but probably worth a look tonight.

10 per hour but a very reliable meteor stream going back to 500BC.
