Corwin's Notes
=====
NGC 3148 = GM UMa = HD 88512 is only a star. JH's description reads "A star
7m has a photosphere 2 or 3 arcmin diam. Sky perfectly clear; glass quite
clean; windy. Another * of same mag viewed presently after has no
photosphere." There is certainly no bright nebulosity that large around the
star, and it is not a double or multiple star, either. Its only "peculiarity"
is that it is an eclipsing variable.
JH has a couple of other stars which he suspected of nebulosity, too, which
show none today. These must be illusions of some sort, though difficult to
account for. Perhaps they were caused by very thin, evanescent clouds or fog?
