Solar eclipse 2015

Jana Horak, 26 Mawrth 2015

The days before Friday 20th March, had staff in the Department of Natural Sciences watching the weather forecast with great attention.  Friday 20th March 2015 was a really special day as we had the opportunity in Cardiff, weather permitting, to see a partial eclipse of the Sun. This does not happen very often, the next one won’t be until 12th August 2026. 

On the Thursday we had a great start to the celebration by hosting an evening of talks on eclipses at the Museum. These were given by Dr Chris North, Dr Rhodri Evans, Dr Mark Hannam, astronomers and physicists from Cardiff University; and we all felt much better informed as to what we knew about the sun, why an eclipse was occurring, and what eclipses tell us about gravity. Equally important was a talk by Jenni Millard, an undergraduate student but experienced astronomer, on how to view the sun safely. Having listened intently the audience were issued with free solar eclipse viewing glasses.

Friday morning and we were in luck, a perfect sunny morning and all that worry about the weather had paid off!  By 8.00 a few people had already arrived outside the Museum, by 8.20 there were many more. At 8.22 we saw the first contact of the eclipse. For a short while the sun was almost obscured by the trees in the Gorsedd Gardens, but not for long. With colleagues from Cardiff University and the Institute of Physics we provided a range of methods to view the eclipse safely. These included a solar telescope that provided the greatest detail of the sun’s surface, pinhole viewers, ranging from boxes and tubes to simple card and paper, solar viewing boxes, colanders and eclipse glasses. Most visitors had noted the warnings about safe eye protection, only a few needed reminding that two pairs of sunglasses wouldn’t do the job!

Over the 126 minutes of the eclipse from first contact of the moon until we saw the entire sun once again, over 1000 people viewed the eclipse on the Museum steps with the viewing glasses provided. In total we estimate that over this period nearly 2000 people joined the event. At one point the queue disappeared round the corner of the Museum into Park Place almost to the University! However this was a great event with a fantastic atmosphere of participation and patient queuing.

Rwyf newydd gychwyn fy mhedwaredd wythnos fel Prif Guradur Adeialdau Hanesyddol yma yn Sain Ffagan, a dyma fy mlog cyntaf. Archaeoleg yw fy nghefndir, ac yn bennodol, archaeoleg arbrofol.

Mae’r math yma o ymchwil archaeolegol yn arbrofi’r syniadau sydd wedi tyfu fel canlyniad o waith cloddio archaeolegol. Yn y bôn rydym yn trio codi rhywbeth a fyddai yn gadael yr un tystiolaeth a ddarganfyddwyd, os cloddiwyd yn y dyfodol. Mae hwn yn herio ein syniadau a codi mwy o gwestiynau.

Tai Crwn o'r Oes Haearn

Dros y blynyddoedd rwyf wedi adeiladu pedwar tŷ crwn wedi seilio ar archaeoleg cartrefi Oes yr Hearn. Gan bod yr archaeoleg yma yn gallu bod yn fâs iawn (ond rhyw 30cm o drwch), mae pob elfen o ail-greuad uwchben y ddaear wedi’i seilio ar waith dyfalu – ei hun wedi seilio ar y dystioilaeth sydd wedi goroesi. Fel allech ddychmygu, mae gweithio allan strwythur adeilad sydd heb yw weld mewn 2,000 o flynyddoedd yn eitha sialens, ond un boddhaol. Felly, mae gen i bleser mawr i fod yn rhan o gyweithiau arbrofol newydd yr Amgueddfa - ailgreuad o ffermdy o Oes yr Haearn, wedi ei seilio ar dystiolaeth o Fryn Eryr yn Ynys Môn, a neuadd ganoloesol Llys llywelyn, wedi ei seilio ar dystiolaeth o Llys Rhosyr, eto yn Ynys Môn.

Mae tô y ffermdy yn cael ei doi gyda gwellt ar y funud, ag yn fuan mi fydd y tŷ yn ddiddos. Mi fydd hwn yn rhyddhâd mawr gan bod glaw trwn dros y Gaeaf wedi atal y waliau clai, 1.8m o drwch i sychu mor gyflym a gobeithio. Mae waliau o glai yn gymharol anarferol gan taw waliau gwial a dŵb neu cerrig sydd wedi eu darganfod gan amlaf. Hwn fydd yr ail-greuad cyntaf o dŷ crwn o’i fath.

Llys Rhosyr - Llys Canoloesol

Mae waliau y ddau adeilad sydd o’r Llys mor uchel a fy mrest, ac mae’r saer maen yn barod i gychwyn y fframau ffenestri. Fe ddarganfyddwyd y Llys yn Ynys Môn, ac fe’i gloddiwyd rhwng 1992 ag 1996. Mae’r waliau cerrig ond yn sefyll ryw fetr o daldra. Felly, yn yr un modd a’r ffermdy, ail-greuad wedi seilio ar dystiolaeth archaeolegol yw hwn.

Mae hanes ysgrifennedig o’r cyfnod, fel ‘Brut y Tywysogion’ yn awgrymmu fod neuadd frenhinol yma, a fu yn un o Lysoedd Llywelyn ap Iorwerth yn ystod hanner cyntaf y drydedd ganrif ar ddeg. Y peth dydyn ni ddim yn gwybod gyda sicrwydd yw pa olwg oedd ar y neuadd. Mae’r wybodaeth yma wedi ei seilio ar gymhariaethau gyda neuaddau Brenhinol eraill, ag adeialdwyd yn yr un cyfnod, fel a welid yng Nghastell Conwy a Phalas yr Esgob yn Nhŷ Ddewi.

Gan fy mod yn bwriadu ysgrifennu blogiau cyson ynglyn a’r datblygiadau diweddaraf, fe wnaf anelu hefyd I amlinellu y gwaith sydd wedi digwydd hyd yn hyn, felly fydd genych fwy o syniad ô’r adeilad hynod yma, ac ein ymgeision i ddod ar Llys yn fyw unwaith eto.

sut i wybod bod oen ar y ffordd

Bernice Parker, 18 Mawrth 2015

Helo na Sgrinwynis - dyma'r ateb i'r cwestiwn fwya poblogaidd o'r sied wyna eleni.

'Sut allwch chi ddweud bod dafad ar fin rhoi genedigaeth?'
 

Dyma rai o’r prif arwyddion:

  • Cuddio yn y gornel - yn y gwyllt, byddai hyn er mwyn osgoi ysglyfaethwyr
  • Llyfu gweflau – paratoi i lanhau’r oen wedi iddo gael ei eni
  • Aflonydd – codi a gorwedd bob yn ail
  • Pawennu’r llawr – creu ‘nyth’ i’r oen gael ei eni ynddo
  • Corff i’w weld yn tynhau yn rheolaidd
  • Llysnafedd, bag dŵr neu bâr o draed i’w gweld yn dod allan o’r ddafad!

A gan bod fi mor hael - dyma llun o'r cwads cyntaf erioed Sain Ffagan. Ganwyd neithiwr...

Ffrwd byw o’r sied Ŵyna

As part of the redevelopment project at St.Fagans National History Museum, we wish to open our doors to volunteers and invite them to work alongside the Preventive Conservation team, helping to care for the collections on open display in the historic houses. There are hundreds of objects on display ranging from furniture, textiles, pottery and agricultural equipment. Providing plenty of opportunities to share a skill or learn something new.


Caring for this site is no mean feat, we currently have 26 furnished properties including a castle. Plus there are 4 new buildings on the way, including a medieval hall and the Vulcan pub! So plenty to keep us busy. The Museum is also open throughout the year and can have up to 700,000 visitors during that time, which means we are kept on our toes making sure everything continues to look good, day in and day out.

This work is a combined effort, involving staff from many different sections, which often goes on behind the scenes unnoticed by visitors. However, we wish to change this and provide opportunities for volunteers to assist us, not only in the care of objects, but also contribute to interpretation and help inform the public.


We are currently refurbishing one of the cottages on site, aiming to provide a comfortable and creative work space for our new collection care volunteers. We hope to start recruiting in May so if you're interested, I'll be posting more updates as the project continues to progress.

We’re in the process of preparing objects to go on display in the new galleries that are being built on the site of St Fagans.  #makinghistory  

As the textile conservator, I have come across three objects that, though they are kept in the textile store, are not exclusively made of textile but have paper components and have botanical specimens attached, neither of which come under my area of expertise.  Hence, I’ve roped in my two colleagues, the  Senior Conservator Archives and the Senior Conservator Natural Sciences and the three of us will now jointly treat these objects. 

Joint projects are always a great opportunity for sharing skills and learning from colleagues so we’re all really looking forward to this!
