| 148 | Feb 01 1900 | x 12452 For flexure of Dec. Axis & Effect of temperature. R.A. -15 rev. Sector "2". Instrument allowed to run between exp. Exp. Began HA Ended. 1 B 7 51 + 2 29 W B 7 53 + 2 8 51 + 3 29 W 8 54 - Clock skipped two beats previous to the 2nd. exp. Clock skipped more beats & began running very poorly and before time for the 3rd exp. The sector ran out, so plate is probably useless. There, on pier reads +10.3. As the clock is running poorly & U Coronae needs to be taken. I will not attempt to repeat this plate. | ||||||||||
