V. An Observation on an Occultation of Cor Leonis by the Moon, on Thursday, March 12, 1747, in Surrey-Street in the Strand, London, with a reflecting Telescope, made by Mr. Short, F.R.S. which magnified about 100 times; communicated to the Royal Society by J. Bevis, M.D. Read March 19. 1746-7. Apparent Time. | d | h | m | s | |---|---|---|---| | 1747, Mar. 12 | 8 | 24 | 19 | The Star immers'd into the dark Limb. | d | h | m | s | |---|---|---|---| | 9 | 27 | 4 | It emerg'd from the enlighten'd Limb a small Matter to the West of the Moon's Zenith. | d | h | m | s | |---|---|---|---| | 44 | 4½ | The Moon's preceding Limb pass'd the Meridian in the Transitory. | d | h | m | s | |---|---|---|---| | 44 | 21 | The Star pass'd the Meridian. Mr. Short, another Gentleman, and myself, agreed to a single Second in the Immersion, with different Telescopes; but I saw and pronounced the Emer- sion 2 or 3 Seconds before them.—There had been an exact Observation of the Sun's Transit at Noon; and the Clock gain'd about half a Second a Day. We reckon Surrey-Street 27 Seconds in Time West of the Royal Observatory at Greenwich. Mr. John Catlin had a few Days before deliver'd me a Computation of this Eclipse, corrected from two Places of the Moon, observ'd the 28th of February and the 2d of March 1729, corresponding pretty nearly with her present Situation; as likewise from the Star's Position, as I had rectify'd it from several late Observations; and this gave the \[ \begin{align*} \text{Immersion at} & \quad 8 \frac{26}{3} \\ \text{Emersion} & \quad 9 \ 30 \end{align*} \] J. Bevis. VI. An Observation of an uncommon Gleam of Light proceeding from the Sun, by Mr. Peter Collinson F. R. S. Read March 19. On the 8th of March 1746-7, near 1746-7. 8 o'Clock in the Morning, as I was riding within three Miles of Brentwood in Essex, there appeared a singular Phenomenon in the Heavens; the Sketch (Tab. . Fig. .) may give some Idea of it. The Morning was fine and clear, the Sun shone bright, no Cloud to be seen, but the Air a little hazy: Where the Phenomenon appeared, which was a bright cloudy Spot, seem'd a very small Portion of a Rainbow,
