2023 Edition Updates

On p. 44, last line, change the reference from p. 205 to p. 201

On p. 135, the times given for Victoria should be 3 hours earlier than shown. I.e. Victoria, BC 8:08 9:20 10:38

On p. 46, the Time Zone map is reported as somewhat illegible. Use this link
http://astro.ukho.gov.uk/nao/miscellanea/WMTZ/Wmtz211122.pdf

On p. 149, the URL at page bottom should read "wms.lroc.asu.edu/lroc" (i.e. all lowercase)

On p. 150, Standard Edition, in the example at page bottom, the interpolated value for 43° N is 21:25, and the Tabular Delay is 20 min. Thus, using the chart, the correction is 30 min, giving a moonset time of 21:55 (22:55 EDT)

On p. 150, USA Edition, in the example at page bottom, the interpolated value for 42° N is 21:41, and the Tabular Delay is 55 min. Thus, using the chart, the correction is 4 min, giving a moonset time of 21:45 (22:45 CDT)

On p. 171, USA Edition, 7 lines from the bottom, change the reference from p. 176 to p. 173

On p. 214, line 3, ignore the reference to p. 244

On p. 240, para. 1, change the wording to 
The following two pages contain ephemerides for those minor planets (identified by number and name) that reach mag. 9.9 or brighter during 2023 and are positioned more than 60° from the Sun. The table is ordered by the date of greatest elongation from the Sun, shown in the headers, along with the magnitude. It is rare that any object is exactly 180 degrees opposite the Sun, so, for the purposes of observing, the time of greatest elongation is more important than opposition. In the table, Mag. is visual magnitude. Elongation dates are given after the minor-planet name; a dash (—) indicates no opposition in 2023. 

On p. 269, USA Edition, middle of 2nd paragraph, change the reference from p. 208 to p. 204.

On p. 283, line 21, change the magnitude of Toliman from 4.4 to 5.7

On p. 297, Table 1 is incorrect. Use the table in the PDF below

On p. 302, paragraph 4, line 1, revise reference to "pp. 284–288"

On p. 302, paragraph 4, 4 lines up, revise reference to "pp. 287, 288–291"

On p. 306, USA Edition, change the reference in paragraph 4, line 3, from p. 332 to p. 330

On p. 332, in Editor's Note 1, revise the page reference in the last line to "pp. 307 and 321"
