  1. Congrats to Brian Kloppenborg for completing his PhD dissertation, about eps Aur, at Univ. Denver. Watch for the publications to follow.
  2. Spiral arms in the disk of HD 206462 - proxy for dynamical processes in many a #disk . NAOJ Subaru result: nasa.gov/topics/univers…
  3. Participating in an AAVSO webinar now - transcript available soon at AAVSO.org #webinar
  4. another one to watch: astronomyjc on twitter.
  5. Reports in prep for special issue of J.AAVSO - aavso.org/journal-aavso
  6. Relevance of the disk: astrobites.com/2012/01/19/sig…
  7. Observing for 2011 at an end with a good session on SpeX last weekend, and a wind-driven shutdown at CHARA the week before.
  8. Back on scopes tonight, CHARA+MIRC, post-eclipse calibration. Herschel data confirms very low gas/dust ratio (ApJLett submitted).
  9. HSO disk detection suggests low gas to dust ratio. New spectra: threehillsobservatory.co.uk/astro/spectra_…
  10. Herschel Space Observatory/PACS instrument observations obtained on Sept 9th and Sept.21st - far IR photometry. Detection will imply disk..
  11. Updated spectroscopic database for epsilon Aurigae eclipse studies: threehillsobservatory.co.uk/epsaur_spectra…
  12. JAAVSO is planning a special edition dedicated to epsilon Aurigae: The formal Call for Papers can be found at: aavso.org/jaavso-call-pa…
  13. Check out my light curves at tinyurl.com/epsaur - with thanks to the AAVSO observers who contributed to this BVRIJH dataset!
  14. Eclipse is essentially over, but the new season of post-eclipse calibration observing has started, featuring an IRTF/BASS mid-IR spectrum.
  15. Godspeed Atlantis! Welcome back to outer space.
  16. Recent report, V=3.06 - nearly full strength. This eclipse closely resembles the last, with some subtle differences...
  17. Happy Bloomsday. Latest reports suggest V = 3.15, slowly recovering full brightness.
  18. Lost in the glare of solar conjunction... see you on the other side!
  19. After a plateau at V ~ 3.35 (D ring?), epsilon Aurigae seems ready to roar back to full brightness... low in the west but still viewable.
  20. Egress continues - approaching V ~ 3.35 this week, up from 3.75 a few weeks ago. Back to full strength, V=3.0 by mid-May?
