I think yes. Note there is bus between conv center and hotels and Hilton/Waikiki. Schedule here:

John Herschel reported on
#Betelguese's variability in 1840, & compared his years of observations to his father's (William). I love Herschel's description of photometry, trying to quantify by-eye estimates, and trying to make sense of the variability: http://articles.adsabs.harvard.edu/pdf/1840MNRAS...5...11H …pic.twitter.com/kie3PuD0Qh

#Betelgeuse fnter than 1st mag looks less remarkable when looked at over a century. Here is nice discssn frm Dolan+2016 on prospects for supernova, prhps w/i next ~100,000 yrs.

Al-Sufi's description of Orion &
#Betelgeuse from Kitāb suwar al-kawākib, medieval treatise on astro & Arabic 'update' to Almagest from 964 (transltd by Ihsan Hafez, 2010 PhD). Centuries later in Europe, a scribe mistransliterated Arabic Y in Yad al-Jauza' to B & rest is historypic.twitter.com/AjhJa4GozM

Regarding
#Betelgeuse's "historic" dimming, here's V-band & photovis magnitude estimates from@AAVSO database over past century. *You* try maintaining constant luminosity w/~20 solar masses spread out within the size of Jupiter's orbit, w/convection & nucleosynthesis is 3D!pic.twitter.com/e2kojEZXAC

Showed
#asteroid num plot below last year, with original plot by De Meo+2015, & annoying labels of limited laugh value are mine. Long term N_asteroid doubles about every decade w/interesting historical pauses. But... N_exoplanet > N_asteroid by ~2047? https://twitter.com/GeertHub/status/1038107913611501568?s=20 …pic.twitter.com/m9aZ9kZkg2

In case there was any confusion about what a "near-Earth object" is... there is language in the
#Senate's#NASA Authorization Act of 2019 (p.54)! Surprised seeing term "Astronomical Units" in a bill too! https://www.commerce.senate.gov/2019/11/commerce-leaders-introduce-the-nasa-authorization-act-of-2019?et_rid=35344298&et_cid=3070572 …#NEOs#NEAs#PlanetaryDefensepic.twitter.com/DmfyqlpfrP
