    Nick, you should have been at my “Speed of Light” talk to Newbury in January.  I even measured it with some chocolate and a microwave oven.  One of my slides is attached.  Your statement should be 1802.6175 Gigafurlongs per fortnight!

    Of course it’s just possible they mean the Elizabeth Tower.  Big Ben is a big bell but not that big.

    Total cloud cover was forecast. Outlook seemed better in SE England so at midnight I started driving SE in search of a clearer sky.  Found them at Cobham Services 79 miles later.  Sky deteriorated quickly, intermittent views,  I was taking a sequence of images but clouds intervened about 30 sec before flash.  This is at 5.08, 2 sec exposure with 6D using ETX125, the star on the right that has just been revealed by the moon is 7th magnitude HD 67150.

    Think if you elminate time dependency, average distance, it’s Mercury.

    Closest at some time, Venus.

    Hi Garion,

    Picked up the Philips lunar map that Bill mentioned in TheWorks store for £3 about a week ago. https://www.theworks.co.uk/?q=Philips%20Moon%20Map%202018

    Bad luck.  Managed to get it.  Was going to use a planetary camera but events intervened.  Plan B was a DSLR so lousy timing accuracy.  All I can say is star was visible at 19:19:04, missing at 19:19:07 and back again at 19:19:10.

    Here’s what Oxfordshire Council are saying:

    Many thanks for your enquiry,  our current lighting policy is to use 3000K colour temperature LED’s on residential roads and 4000K on traffic routes (which is currently being reviewed as part of this project).

    I queried what was happening in Oxfordshire.

    Many thanks for your enquiry,  our current lighting policy is to use 3000K colour temperature LED’s on residential roads and 4000K on traffic routes (which is currently being reviewed as part of this project). Our policy is to dim street lights on residential roads by 50% light output from 22:00pm to 06:00am and traffic route to 75% light output from 00:00am to 06:00am.

    This is in Banbury. Not possible to turn lights off because I live in suburban environment.

    Glad it was new to you Martin. Wondered if you’d seen it.

    Missed the DVD at Astrofest, I’ll look out for it at Winchester.

    Here’s my video of totality through 70mm refractor in a field near Salem, Oregon. Used 550D, as you can see a mod’d camera, Univ retrospect a mistake but I wanted some nice red prominences. Everything else turned out red as well.

    Richard Fleet can be heard on audio as well as “Total Eclipse of the Heart'” blaring out on someone’s car stereo.

    Wish I’d met him.

    For those of you who do not want to make Murdoch any richer here is the obituary.

    Embarassed to post this very inferior image but I was pleased to capture it with only a 1 second exposure through a 70mm f6 refractor.

    No tracking available hence the short exposure.

    Observed from a windy hilltop on Jan 2nd. Camera was a 6D. Image has been cropped, Theta Capricorni is at top.
