9th MARCH, 1898.

The phenomenon of Mock Moons was observed at King’s Lynn, 
on the evening of the 9th March, 1898, by several of the inhabi- 
tants. My personal observations were as follows : I left my house 
at 11.15 p in. ; as soon as I came into the street I noticed that the 
moon, which was nearly at its full, was surrounded by a large halo 
(45° across), within which was the planet Jupiter, towards the West 
side of the halo, and situated in the luminous part of the circle 
was a rounded patch of light, looking like a large star in the 
act of bursting through a bank of cloud ; as a matter of fact 
I thought it was Venus, but a moment’s reflection showed that 
Venus could not occupy this position in the sky. On the Eastern 
or opposite side of the halo, was a similar but rather fainter, 
rounded luminous patch. The two Paraselen® were circular in 
form but brighter in the centre than they were circumferentially. 
They were opposite one another, with the moon between them, and 
were wider than the halo. From the West Paraselene a beam of 
light extended Westwards, parallel to the horizon, and in the same 
line as the two Mock Moons, which extended some 30” or 40° below 
the halo. A little later in the evening this horizontal line of light 
was supplemented by a second, originating from the Western Mock 
Moon, also extending Westwards, not exactly parallel to it but 
inclining slightly downwards towards the horizon. The second 
beam was never very conspicuous, and soon faded. The Western 
Mock Moon was, when first seen, much the brighter, but it faded 
soonest, and at 1.10 a.m. had entirely disappeared The Eastern 
Paraselene was however still visible, as a small patch of light.
