The first one was observed as a pale glow along the horizon up to about 8o but by 12:45 a.m. the shafts of pale green appeared and continued until the end. The display on the night of the 18-19th was the most brilliant witnessed in this section for many years, with the streamers of pale green vibrating and appearing from all quadrants converging at the zenith. 1941 9 18 NEW HAVEN CONNECTICUT [monthly summary only] 1941 9 18 EASTPORT MAINE Aurora observed in the early evening. 1941 9 18 GREENVILLE MAINE [monthly summary only] 1941 9 18 PORTLAND MAINE [monthly summary only] 1941 9 18 BOSTON MASSACHUSETTS Aurora Borealis became brilliant before 8:00 p.m., attaining greatest intensity 8:30 to 9:30 p.m. At 8:25, the most noticeable feature was a dark bow in northern sky from which streamers darted toward the zenith. At 8:35 a light streak extended from horizon Az. 290o, entirely across the dome, through the zenith, to Az. 270o on the eastern horizon. At the frequent intervals streaks like searchlight beams converged from all directions to a focal point near the zenith. Adequate description is precluded by the variety of manifestations and rapidity of changes, far exceeding those noted by this observer in March, 1918, the only comparable display recalled. Colors of streamers most pronounced in western sky, and were pink, red, and green predominating. No portion of the dome but what showed some display at one time or another. Landscape illumination was equivalent to that of a clear moon at quarter. Display faded somewhat after 11 p.m., but still faintly visible for some time thereafter, and some evidences of it continued to 4:30 a.m. of the 19th. 1941 9 18 NANTUCKET MASSACHUSETTS [monthly summary only] 1941 9 18 CONCORD NEW HAMPSHIRE Unusually brilliant auroral display continued all night and into next day.

Again, on the 18th, an especially brilliant aurora was first observed at 7:15 p.m., and noted at times till after midnight; last observed at 1:30 a.m. It was most brilliant between 9:00 and 10:00 p.m., when bands of light extended from a point in the east through the zenith to a point in the west. It was a beautiful sight with pale pink and green colors predominating. The lights were so bright that the effect was not unlike bright moonlight on the landscape. On this occasion the arch was unusually high. It was still very prominent till after 10:30 p.m. The lights were still discernable at 1:30 a.m. on the 19th, but weakening at that time. 1941 9 18 PROVIDENCE RHODE ISLAND A spectacular auroral display was observed from 8:00 p.m. to about midnight. The Aurora was described by Prof. Charles H. Smiley, of Brown University as "a most remarkable one". Masses of streamers formed a perfect arch across the northern sky, and continued to move slowly upward changing its shape from minute to minute until it stretched from east to west directly overhead. Between 8 and 9 p.m. the shafts of light streaming upward formed a nearly perfect circle at the zenith, known to astronomers as a "corona", a phenomenon rarely seen in this vicinity. Light green in color during much of the display, but later it showed bright flashes of red and at one time the lower ends of the streamers were edged with rainbow tints, that came and went with the rapidity of lightning. 1941 9 18 BURLINGTON VERMONT A very brilliant aurora occurred on the evening of the 18th, continuing into the 19th.
