Yes, I know that Blogging has been light, but currently Professor Astronomy is currently 1650 miles (about 2650 km) away from the warm, sunny Sonoran Desert (where it is finally threatening to rain and a snow advisory has been issued). In the past 3 days, he has put 500 miles on a rental car, with 500 more to go in the next few days. So, hang tight, he will be back.
And, boy, is there a story of travel adventure to tell! ;)
