    The videos from Saturday’s meeting will shortly be available.

    David Arditti’s Skynotes for January are already on our Youtube channel here. The full videos for all three talks will shortly be available on our website via the meetings page here. They are currently being transcoded and that takes a few hours. The two talks were:

    • William Stewart: ‘Meteors – Advances in observation  & analysis’
    • Robin Leadbeater: ‘Using low resolution spectroscopy to confirm supernova discoveries’

    Remember that you need to be logged into the website to view the entire video.

    Nice talk Robin, just been through it. William’s next.

    Regards Andrew 

    David Swan

    Great talks; sorry I couldn’t make it in person due to commitments. David

    Thanks for the videos Nick. Excellent talk by Robin, explained the difference between the different supernovae spectra and made it much clearer! Now to watch William’s talk.

    Thanks for the videos. I was not able to get to the meeting and they are a real help.

    However, I don’t know if it’s just my set-up but,  there’s somthing weird going on with the downloaded MP4 videos.

    Thin horizontal lines flicker. In the starfield shots, random stars pop into and out of existance on an about 1 to 2 second cycle.

    Is this due to the transcoding to MP4?. Are there any parameters you can twiddle to stop it?

    Roy. It may be the video compression but different decoders behave differently too. Could you give me a specific video and time offset where the effect is significant so that I can have a look. Nick.

    I have just got round to watching David’s Sky Notes which I missed as I had to catch my last train north.

    SN2018gj imaged there by David Swan and Peter Carson is interestingly another supernova discovered and confirmed spectroscopically by  amateurs.  (Patrick Wiggins and Etienne Bertrand respectively)   

    Patrick Wiggins first put the news of his possible discovery out on the supernova discussion forum where he was advised to upload it onto the Transient Name Server post haste !

    I was clouded out but realised it was potentially bright enough to be recorded spectroscopically using a standard ALPY 600 so I put an alert out on the ARAS forum which Etienne picked up.

    The confirming spectrum was taken just 9 hours after the discovery
