John Barrett 1994 notes on firefighters tragedy in Colorado 1994--Astron In June 2000 "Astronomy" magazine Astronews pp 24-26 Andrea Gianopoulos has 'solar update' Seeing Moss and the Whole Sun' TRANSITION REGION AND CORONAL EXPLORER 'spongelike features thgat resemble earthbound moss = clues to sharp temperature rise moving from photosphere surface to outer atmosphere [corona]. This occurs at base of high-pressure coronal loops in extremely active areas, in large bright patches six to twelve thousand miles across from a thousand and 2500 miles above photosphere - hot gas or plasma emitting in extreme ultraviolet. Bart De Pontieu of Lockheed-Martin Solar and Astrophysics Lab says "These observations provide a glimpse -how the sun's magnetic field changes from a chaotic jumble at the photosphere to the well-organized magentic field present in coronal loops." Article also discusses how SOHO detects 'weather' on far side of sun. I am planning a list of "interesting" stars using Motz and Nathanson "Constellations" as a source and the Groombridge catalogue and looking for other references. Some items - very bright Wolf- Rayet starts, O and b stars - pre main sequence stars like T Tauri - clusters especially near ones like Hyades, Pleiades, Big Dipper, and new group in Hydra and the globular clusters which are very old and out in halo away from plane of galaxy - Population Two stars of which Groombridge 1830 is said to be nearest at 28 light years in Ursa Major.- nearby stars less that 30-50-75 light years - young stars including the star forming region in Orion trapezium - Theta Orionis - and some near ones in Taurus - variable stars especially RR Lyrae - very old and sometimes in globular clusters and bulge approaching supernova as are bigger, younger Cepheids including Polaris and Deneb - stars with high and low metallicity, high spin, lithium.This will be a long term project, but I call attention of David Latham, Doug Wadsworth, Sean Root. Correections and contributions appreciated. -John Barrett - Below are some notes mailly from the ?Constellations" text.
