jambouk Posted March 13, 2017 Share Posted March 13, 2017 NASA are conducting a survey of amateur astronomers to see what kind of kit we are observing with and what time of the day we use it. It seems they are "making an assessment of the hazard potentially present to the general public as a result of NASA's satellite-based climate science lidar measurements"; this is the wording used in an email sent out by the Royal Astronomical Society. The survey seems fairly straight forwards: https://docs.google.com/forms/d/e/1FAIpQLSclyyQRipQ_14LPSUsaJz51SpYIwzE5p3yftkXzWkwx8oDnnw/viewform?c=0&w=1 I know nothing more about it, sorry, but I'm happy to help NASA.

jam1e1 Posted March 13, 2017 Share Posted March 13, 2017 thanks for the link..... As a side comment, wonder if this explains occasional flashes people have reported to have seen in the sky?! (i have seen very brief flashes on a couple of occasions) Link to comment Share on other sites More sharing options...

Uranium235 Posted March 13, 2017 Share Posted March 13, 2017 Survery done... and an enlightening explanation of Lidar systems on satellites. Not sure ive ever come across one in any of my subs, not sure what it would look like either! Link to comment Share on other sites More sharing options...

Louis D Posted March 13, 2017 Share Posted March 13, 2017 And governments keep telling us not to shine green lasers into the sky (which are really handy for pointing telescopes), and here they are shining them from the sky down onto us! 2 Link to comment Share on other sites More sharing options...
jambouk Posted March 13, 2017 Author Share Posted March 13, 2017 In fairness, I think they are trying to monitor things and save the planet and the entire human race... 1 Link to comment Share on other sites More sharing options...

Agreed, but they've done a really poor job of alerting the public. This is the first I've heard of it. 1 Link to comment Share on other sites More sharing options...
Hawksmoor Posted March 13, 2017 Share Posted March 13, 2017 Thanks for sharing. I have submitted a completed survey. Bright green lights in the sky. Reminds me of the beginning couple of chapters in 'The Day of the Triffids'. We best go out and weed the allotment. 1 Link to comment Share on other sites More sharing options...

SilverAstro Posted March 14, 2017 Share Posted March 14, 2017 (edited) Just when Iridium flares were passing into history ! This is all we need At least Iridium wasnt scary. Where do we get / do they provide predictions ? EDIT Heavens_Above have it listed. Edited March 14, 2017 by SilverAstro Link to comment Share on other sites More sharing options...

DeepSkyBagger Posted March 14, 2017 Share Posted March 14, 2017 Interesting that they put in capitals 'NEVER LOOK DIRECTLY INTO A LASER WITH YOUR EYE'. I put in the comments: 'Tell you what. I'll promise that I'll NEVER LOOK DIRECTLY INTO A LASER WITH MY EYE if you promise never to shine one down my telescope tube. Fair?' 7 Link to comment Share on other sites More sharing options...
