    Nice one. Thanks Nick!

    Cloudy here in Birmingham Nick,  so nice to see it in clear Essex skies!

    Hi Jeremy,
     
    Here are my Birmingham stats.  Last years numbers in brackets!
     
    Observable nights (not counting brief gaps) = 112 (93)
    37 (59) clear and 75 (34) partially clear (50% cloud or more).  Of these 112 nights 53 had Moonlight interference.
    Best month – Feb & July with 13 nights each (April with 12 nights)
    Worst month – September with 6 nights (January with 3 nights)
    Number of hours spent at eyepiece = 247.27 hours (191.18 hours)
     
    The weather forecast (for Birmingham) for cloudy/clear nights was incorrect on 53 (60) occasions, so a slight improvement for the Met. office!
     
    The sky conditions continue to deteriorate here in Birmingham, with increased light pollution and the clarity of the sky worsening year after year – for reasons which I can’t explain. The Milky Way was ‘glimpsed’ on just one occasion in 2014 – Aug 4th.
     
    Look forward to seeing other members stats for 2014.
     
    Happy New Year!

    Thanks for the greetings Paul.  Have a Happy Christmas yourself – and everyone in the BAA too of course ๐Ÿ™‚

    R CrB is now visible with binoculars for the first time since 2007.  As of the evening of Oct 11 it could be seen with 10×50’s (from Brum) at magnitude 8.8.  The rise at the moment is ~0.1 mag every 2 days, but this could change of course in the coming days/weeks.    

    This looks as if it could be the recovery we have waited 7 years for.

    Indeed Howard. The recovery started around April/May this year, and R CrB is now at it’s brightest level for 15 months or so. The previous partial recovery was slow, taking around 18 months to complete 4 magnitudes.  This one is rather steeper, taking just over 3 months to cover the same magnitude.  Might this mean that R CrB will get brighter this time?  We will have to wait and see.  

    I’ve uploaded an up-to-date light curve from BAAVSS observers to the front page of the VSS web pages.  Unless anything else interesting happens I’ll try to keep this plot updated weekly and post to the web site, so that we can all see if this recovery is the real deal or not.

    Clears skies,

    Hi Martin,

    Thanks for the tip. As a big Will Hay fan I’ll be recording it (although I have seen it).

    We had a Will Hay night at the Heart of England AS last year – DVD’s shown on big screen, with the support act being several episodes of Shaun the Sheep.  Astronomy can be fun in many ways, especially at the HoEAS!  The room was full too ๐Ÿ™‚

    Just gave my votes Nick.   Good idea!  Must find time to go through your archive and vote too.

    OK Nick. I’ll give it a try and contact you offline.

    I still had a few issues with Win7 whilst streaming.  The video(s) would stop every 10 minutes, and I had to click to continue!  Didn’t stop me enjoying John Mason and David Boyds presentations though.  Hope to watch the rest over the weekend.   Good stuff.

    I can watch and listen using Win 7 and Chrome (laptop), but not Win 8.

    Nick,

    I have no audio on any of the video’s whilst watching online – Windows 8 using Chrome.  If I try IE I get logged out each time I select a video.

    It will be 600 years since Agincourt on Oct 25 2015, so I vote for Henry V or a silhouette of an archer drawing a yew bow. Nothing to do with astronomy, but who cares.  No one reading this will be alive for the next centenary, so lets celebrate! Much more interesting than dormant Cometary nuclei anyway ๐Ÿ˜‰

    Hi Dave,

    Glad to hear you’ve come back to us.  Might we see some of your VS observations in the VSS database now? ๐Ÿ˜‰

    Hope we’ll get to see you at a few meetings.  I think we’ve only met once at a VS meeting a few years ago (a VS workshop wasn’t it?).  Be good to catch up face to face rather than e-mail.

    Clear skies,

    Gary

    Hi Cameron,

    Excellent image.  Well done.  I’m just a few miles North of you in Birmingham, and know how difficult astronomy can be from our orange skies.  This is very good indeed!

    Keep up the good work.

    Nick,

    I would very much like to set up a database of amateur spectra of VS and link it to the VSS website.  Roger and I have spoken briefly about this, and he seems to be ‘up for it’ too.  I’m hopeful that we can discuss further at the VS meeting (York, June 21 see BAAVSS website) and move on from there.  The AAVSO have been slow to move into this field, so I would like to see the VSS take the initiative.  

    Robin:  Very impressive stuff at this faint limit.  Many congratulations.  I was singing your praises to Bradford AS last night, where I was speaking on Historical Novae.  I’m pretty sure they will be contacting you with a view to a possible talk to their group sometime in the future.

    I’ll be at Milton Keynes too, and as a variable star observer myself would be delighted to meet you to discuss the section and VS in general.

    What’s your name by the way?  There seems to be no current link to a profile for anyone posting to the forum at the moment.

    The most surprising thing about this is the amount of these ‘fakes’ which appear on APOD (which I hardly ever look at by the way).  My daughter sends me images from APOD and other sources saying “have you seen this?”.  I have to deflate her somewhat and say it’s a fake.  I just don’t get it.

    Just a simple observation – the subtracted values bring the light curve closer to visual magnitude – so it must be working! ๐Ÿ˜‰

    Hello Nick,

    Speaking personally and with my visual hat on, there is no way a visual observer can compensate for the background galaxy. I’m sure there lies somewhere an obscure equation to allow for this, but I don’t know of it.  I have always been sceptical about applying corrections to visual observations – even for red bias in personal equations – as there are just too many factors to take into consideration.  Far better to leave well alone.

    I can see some unusual behaviour in the light curve in mv compared to V as the SN has faded, and unusually the fading trend is slightly different too, which I find very interesting.  In most cases the trend remains similar whilst there are differences in measured values.

    Your experiments in removing the galaxy from the image are fascinating, but it doesn’t surprise me that your V measure changes.  I hope you’ll keep us informed as to whether you can improve the difference between the two measures.  In the meantime I would urge visual observers who are observing this SN (and lets hope that as it fades visual observers keep at it) not to worry about the galaxy at all, and put all their efforts in to obtaining the best visual measure they can get.

    Gary
