5. IMC 2016: Šegon et al – Croatian Meteor Network: ongoing work 2015-2016 5 Software and Orbit Catalogue Updates - Data processed through 2016. - Only 3 stations remain in unautomated processing mode - Catalogue for 2013 is complete - Catalogues for 2014 and 2015 will be completed this year - CMN_binViewer – Upgraded, various usefull options added - Still to be done: Automated daily / monthly reports, plots, stats...

6. IMC 2016: Šegon et al – Croatian Meteor Network: ongoing work 2015-2016 6 International Collaboration and Results - Last paper on the 2013 meteor shower search published in WGN 43:5 - Jeremie Vaubaillon (IMCCE): dynamical modeling of potential meteor shower association to parent bodies in CMN stream search paper done (to be submitted) - Last year’s Kappa Cepheids announced activity on September 21st observed only visualy by Juergen Rendtel (no video observation confirmations up to date); No announcements for 2016. - Long lasting Taurid fireball meteor train investigation in work

7. IMC 2016: Šegon et al – Croatian Meteor Network: ongoing work 2015-2016 7 Enhanced Low Cost Radiometer - Now using quad operational amplifier - Three photodiodes / three channels, fourth op-amp summing/amplifying - Better full sky coverage and improved S/N ratio - Integrated with an all-sky camera - Total sensor cost: 10€ - RaspberryPi solution is fully automated 2016-01-01 00:01:16 CET

8. IMC 2016: Šegon et al – Croatian Meteor Network: ongoing work 2015-2016 8 RaspberryPi - Video Meteor Processing Solution Update - New detection approach - End-to-end capture/detect/process solution - Opportunity for nework expansion and educational activities

9. IMC 2016: Šegon et al – Croatian Meteor Network: ongoing work 2015-2016 9 Going Telescopic – Why? - Precision orbits is the primary goal ! - High sample rate light curves - Precise deceleration data - More double station meteors compared to moderate FOV networks? - Better flux and ZHR estimation? - Additional data from stars observations CMN sensor configuration: - Kowa 55mm f/1.0 + ICX672 based camera  NTSC Exview HAD II - FOV 5.2°×3.9°  29”/pixel - Limiting magnitude better than 10 m on stars 1 pixel = 14m @100km

10. IMC 2016: Šegon et al – Croatian Meteor Network: ongoing work 2015-2016 10 Going Telescopic – Why? Actually the CMN design choice is: 8X Kowa 55mm f/1.0 + ICX672 cameras per station Effective FOV 15.6°×10.4°, 1920x1280 pixels, 30 fps

11. IMC 2016: Šegon et al – Croatian Meteor Network: ongoing work 2015-2016 11 Going Telescopic – Why? - More double station meteors compared to moderate FOV networks? Smaller ground separation distance required  Higher common volume of sky Smaller range difference to respective stations Fainter limiting magnitude  More sporadic capture 75km 100km 125km 30km 5km

12. IMC 2016: Šegon et al – Croatian Meteor Network: ongoing work 2015-2016 12 Going Telescopic – Simulation Based Expectations All meteors down to +5 m - Very sensitive on radiant distance - Less critical for slower meteors

13. IMC 2016: Šegon et al – Croatian Meteor Network: ongoing work 2015-2016 13 Education and Public Outreach - Low cost radiometer workshop - Meteor train investigation - Collaboration with high schools and universities - Basic and advanced data processing automatization - Public presentations on various meteor related topics - Visnjan School of Astronomy
