Just updated the list of Meyer group ☄️ at www.comethunter.de/groups/meyer... There are now 244 possible Meyer group comets waiting for publication. With the 116 confirmed members there are now 360 members, making it the 2nd largest comet group after the Kreutz group. Still waiting for the parent. ☄️🔭

Hotel booked for August 2026 in Madrid. Yes, Madrid, probably hot as hell then. But the next international workshop on cometary astronomy (IWCA) will take place there on Aug 14, (besides a total solar eclipse) and I'm hoping to have a nice week there with my wife around these events. 🔭☄️

Every new MPEC that is published with a short-arc orbit for a newly discovered comet that gives 5 digit accuracy and an eccentricity that is not constrained to 1.0, makes me wonder if automated routines without human intervention are really always better. ☄️🔭

🦊 Two hunters on a break. A Culpeo Fox is basking in the warm sunlight, in front of our 3.6-metre telescope. Just like the Culpeo uses its senses to hunt for rabbits, our telescope uses HARPS to scour the cosmos for new exoplanets. Read more: www.eso.org/public/image... 📷 F. Murgas/ESO 🔭

Wow, look at this: the carbon intensity of UK electricity is currently only 32g/kWh and 86.5% of our electricity right now is coming from renewables. Come on world, this IS possible! And it will only get better (meaning: cleaner, healthier, less intrusive) 🎉 (graphic from grid.iamkate.com )
