Report on Observations of Naked Eye Stars in Pegasus

Aim:

To observe as many naked eye stars as possible inside the Square of

Pegasus, from a dark site in Oman, so as to draw a comparison between

skies here, Llyn Brenig and elsewhere.

Method:

A dark site was visited at an isolated location in the Hajjar Mountains, and

once dark-adapted a count was made of the naked eye stars inside the Square

of Pegasus. The region was at a high altitude, so there was so there were no

problems with atmospheric extinction. Stars observed on the perimeter of the

square (Alf And - Bet Peg - Alf Peg - Gam Peg - Alf And) would be counted as

being inside the square. Once a star had been positively identified it was

ticked off in Norton's. Observations were concluded when no more stars were

detected.

Results:

The following stars were identified:

Star                      mv

Ups Peg              4.43
