03:05 <galois> [WIKIPEDIA] Chromosphere#cite note-12 | "The chromosphere (literally, "sphere of color") is the second of the three main layers in the Sun's atmosphere and is roughly 3,000 to 5,000 kilometers deep. The chromosphere's rosy red color is only apparent during eclipses. The chromosphere sits just above the photosphere and below the solar transition..."

10:02 <egg|laptop|egg> bofh: also, today in egg, I forgot to take the replacement reticle illuminator I bought for the polar scope

10:03 <egg|laptop|egg> bofh: not that there will be much in the way of observation opportunities tbh

10:05 <egg|anbo|egg> [...] it soon became clear that this was inadequate for much astronomical data, because the time series we analyze are almost always unevenly spaced in time; after all, no other science (except of course meteorology) is so much at the mercy of the weather.

17:31 <egg|laptop|egg> hmm

17:32 <egg|laptop|egg> "Dusan Vuckovic, Petar Rajkovic, Dragan Jankovic and Olivera Pavic" I guess that explains lack of articles

17:48 <B787_300> this will become a huge problem in the US at some point... also nice linear data https://usercontent.irccloud-cdn.com/file/NNRMO8bo/image.png

18:01 <egg|laptop|egg> the “mean” mean anomaly at epoch

18:26 <UmbralRaptop> mean anomaly vs nice anomaly

18:27 <UmbralRaptop> B787_300: I mean, it's already a problem.

18:28 <UmbralRaptop> Looks like some sort of seasonal waviness?

18:31 <B787_300> yeah there is some seasonal waviness

18:31 <B787_300> which makes sense as most loans are given out in fall/spring not summer

23:02 <UmbralRaptop> "When the SWG first met, in September 1984, they projected that SIRTF would obtain a New Start in FY 1987. By December, that prediction had changed to FY 1989, because another project had jumped ahead in line. Although no one knew it at the time, SIRTF would not get a New Start until FY 1998."

23:02 <UmbralRaptop> ow

23:05 <B787_300> too many acronyms UmbralRaptop
