  1. Here is an account of that solitary historic observation. Even in this case however, the planets were only 1.4 degrees above the horizon, and John Bevis did not witness the actual moment of occultation. So there is no complete record of such an event in all human history - http://www.bogan.ca/astro/occultations/1737occl.htm
  2. It's actually worse when the conditions are so/so and you get fooled into believing something might actually be visible... at least today it was obvious from a long way off that there was going to be a no-show.... see you on March 15th 2080
  3. Well it's now approaching 30 years since the last British meteorite fall, which is the longest span since Aldsworth-Rowton from 1835-76. You'd have to say that's surprising, considering the ubiquity of cameras of every sort, compared to earlier times - https://www.lpi.usra.edu/meteor/metbull.php?sea=*&sfor=names&ants=&nwas=&falls=yes&valids=yes&stype=contains&lrec=50&map=ge&browse=&country=United+Kingdom&srt=name&categ=All&mblist=All&rect=&phot=&strewn=&snew=0&pnt=Normal table&dr=&page=0
  4. Remember those cult believers who boarded the UFO travelling behind Hale Bopp...? ....they forgot this bloke
  5. The great thing about this comet is you don't need Stellarium to find it!
  6. Lot of comments for a barely naked-eye object... imagine if this place had been around during Hale-Bopp!
  7. y'all making me jealous. Too dang cloudy here in Ireland and a bad forecast too.
  8. Along with Jonas' M31 image, this is my all time favourite SGL masterpiece. Epic, monumental, stupendous.
  9. And what has a beginning must have an end, right Jim?
  10. I don't think anyone is saying science is 'made up' but that it may not be the 'full truth'. It seems every scientific answer, by definition, provokes a further question... if water is hydrogen and oxygen then what is hydrogen and what is oxygen... if Mozart's brain caused that great aria then what caused Mozart's brain... if the singularity gave rise to the Universe then whither the singularity.... and so on and so on etcetera ad infinitum. In that sense terminology is indeed crucial - as Bohr said, we are 'suspended by language'.
  11. There's a feature in Stellarium under 'sky and viewing options', then 'markings' which shows the constellation boundaries.
  12. Thanks indeed for this generous gesture, will hopefully get to watch as many as possible. I did notice there seems to be an issue with the Dec 13 2008 video, doesn't seem to be loading beyond the first few seconds: https://britastro.org/video/906 it might be just my system, but thought I'd let you know. Thanks again.
  13. Superb. Between your images and those of Michael Jager, we are very fortunate to enjoy comet photography of the highest order.
  14. It's a lovely area of the sky and perhaps overlooked, with Orion/Taurus getting the lion's share of attention from our latitudes.
  15. Yes this is my thought exactly; I feel like I've seen every possible deep-sky portrayal, and that we won't get anything truly different until the days of interstellar travel! But an 'artistic' shot is still of interest, and 'unusual' or time-specific subjects such as occultations, conjunctions, fireballs etc remain both scientifically valuable and aesthetically beautiful.
  16. That's a good point actually, a few wafting clouds can make the scene look more 'artistic'. Great shots everyone. Skies cleared sufficiently here in Ireland too so that's another one knocked off the bucket list. Now to move to Mars in time for the Earth transit in 2084
  17. Quite appropriate of course, considering Gassendi was the first to observe a Transit of Mercury: http://articles.adsabs.harvard.edu//full/1976JHA.....7....1V/0000001.000.html
  18. The only assumption I would make is that if it is artificial, then it must have been intentionally directed towards us. The Voyager craft for example, are expected to travel for a quadrillion years before they would approach a planet as closely as 'Oumuamua did to Earth. I find it quite suspicious that, with over 100 years of quality images behind us, we have never detected an 11th, 12th, 13th magnitude interstellar object i.e somewhat brighter than this one. The volume of interstellar space is staggeringly vast relative to the Solar System, and this object approaching to within 0.16 AU was virtually a collision. When you add in the other unforeseen properties, this is the most interesting object since the invention of the telescope imo.
  19. If you imagine a needle travelling through space, the 'body' of the needle will reflect more light and generate the light curve. But this will not be a true value for the axial ratio, as that could only be derived from the light curve if the 'tips' of the needle were oriented directly towards us. Since this is far less likely, the published axial ratio values are most probably under-estimated. I thought 50/50 was an appropriate balance between the extreme properties of the object versus the unlikelihood that an artificial craft would appear at our moment in history. I'm not sure about your third point, yes there are far more natural objects but this has 6 or 7 unusual properties and it's not from our neighbourhood. Unfortunately we may never know, but if it was artificial it's unlikely to be either random or alone. @Klitwo, the non-gravitational acceleration is unrelated to the original speed of the object (assuming of course that it is a genuine interstellar object and that its motion was not generated artificially).
  20. I'm a bit surprised at the level of cynicism in here.... let's just take the light-curve example. Even the most conservative estimates accept that the axial ratio is 6:1. However, since it's unlikely that the object was viewed edge-on, the probability is that the ratio is higher, perhaps 15:1 or more. This is an extreme geometry for the first interstellar object and, if true, I would say the odds are better than 50/50 that it's artificial.
  21. Hmmm... the technology of the future, or any alien technology, will be easily capable of reversing death.
