The Hawaiian star. [volume] (Honolulu [Oahu]) 1893-1912, 1902-07-16

Prof. Curtis j. Lyons meteorological
report for the month of June is un-
usually interesting particularly in his
discussion of the 'afterglow.' the
"fOreglOw' and the activity at XII
lauea. The report is as follows:
The "afterglow" and morning glow
was very marked throughout the month
being most brilliant about % minutes
after sunset and before sun rise, which
would give an elevation of the dust
stratum of from u to Is miles assuming
that the most marked cOloTing would
take place at the apparent sunset of
that time and elevation. The coloring
shaded off from rich yellow to gray
green, the daytime corona being
Whitish gray. There was recurrence
of activity in the central pit crater. Ha-
lemaumau, in Kilauea, the breaking
upward from below being greatest from
the Bird to the 9Th. What molten lava
there was in the pit was still however
several hundred feet below the main
crater floor and obscured from view by
smoke. Many cracks in the main floor
however revealed heat to the point of
redness just below said floor.
There is still a small patch of snow
visible on Mauna Kea. The main fea-
lures of the month were, LIST the con-
tinued low barometer; End, the unusual
lack of trade wind; Bird the high humi-
dity all making the heat oppressive
although the radiation at night kept
the average temperature down to the
usual figure.
