Just a quick look around the top of Ben Nevis in summer 2014.
Can you really be an eclipse chaser if you’ve only actually chased one eclipse?
My chased eclipse was August 1999 – south west England. Back in the mid 1980s I had a book of fascinating astronomical facts, it listed the dates of upcoming eclipses until the far-off Year 2000. I decided that I’d see that one, and as time passed, I did find myself watching very cloudy skies from a side road near the hurlers stone circle. The sky did darken at the appointed time, the surrounding fields lit up with camera flashes and there was a genteel sense of disappointment when the sky cleared for a glorious sunny afternoon shortly after the end of the eclipse.
I’ve since caught a few other eclipses visible from London, but I’d not gone out of my way to travel to see any. I’ll not count the North American October 2014 partial eclipse as chasing because I was already in the country for other reasons.
Of course it was cloudy for the big event today. My preparation of solar film, pinholes and time-lapse camera was for nothing. With about ten minutes until first contact between sun and moon, I decided I’d at least have a try at logging the change in light levels.
I quickly bodged together an Arduino, an SD card and a light sensor, and put it in the garden. The plan being the thick cloud cover may stop be seeing the ellipse directly, but would act as a perfect diffuser for making whole-sky light level measurements.
The graph shows the result – it got dark(er) when it should have.
The y-axis units should be Lux, but are uncalibrated.
Other eclipses during my life.
July 1982 – No memory of this one.
December 1982 – No memory of this one either.
May 1984 – Vague memory of my Grandfather trying to view this though smoked glass.
May 1994 – Watched this though a pinhole in card held up to my eye.
October 1996 – I must have watched this, but I can’t recall it.
August 1999 – The big one, had planned to watch this since the mid 1980s. Got stuck in traffic close to our chosen viewing spot (along with half of Cornwall and the BBC), watched from the side of the road. Cloudy, but magic.
May 2003 – Far too early for me.
October 2005 – Set up with telescope and camera at work, clouds rolled in. Managed to get the occasional glimpse of the sun in projection though the telescope.
March 2006 – May have tried to watch this one, but it was only a tiny fraction partial eclipse and I was deep in PhD writing up, so no memory of this eclipse.
August 2008 – Another tiny fraction partial eclipse, I think I tried to spot it using a stack of CDs as a solar filter.
January 2011 – Early and cloudy, nothing seen.
October 2014 – Nicely visible from a front porch in Minneapolis
March 2015 – as above, cloudy but at least some data from the eclipse.
I can’t honestly claim to to have been a massive fan of Terry’s writing – I’ve not read all (or much of it) – Robert Rankin was always more my cup of Tea (or pint of Large).
That said I am a massive fan of the man himself and I’ve met many good people, some very good friends, some acquaintances via his fandom.
The news of his passing him me a lot harder than I thought it would. So many good memories.
I’ll raise a glass to him at 8pm tonight.
Doing a bit more snooping around the radio spectrum with the RTLSDR (My HackRF should be here tomorrow!) I spotted these patterns in the transmitted signals from DAB stations.
I’m fairly sure these are not just moiré patterns. I expect they probably tell you something about the multiplexing of the signals in the transmission.
