Lunar eclipse event entries are named by the lunar eclipse date, year and money as 4 digits. For example 200012 means December 2000.

Data fields used:

1. y = year
2. m = month
3. d = day of month (for UTC time at greatest eclipse)
4. t = time of greatest eclipse (UTC) hour:min:sec
5. h = hour of greatest eclipse (UTC)
6. m = minute of greatest eclipse (UTC)
7. imphoto = photo of eclipse (if past event)
8. capphoto = caption with photo
9. imearth = image of Earth as viewed from Moon showing visibility
10. imwide = image of Moon in sky from center of Earth, wide angle showing constellation
11. capwide = Caption text with wide image
12. imclose = image of Moon's hourly timing passing through Earth's shadow
13. ty = type (N=penumbral, P=partial, T=total)
14. nd = node of eclipse (D=descending, A=Ascending)
15. sa = Saros series index
16. dt = duration of totality
17. dp = duration of partiality
18. dn = duration of eclipse
19. ga = gamma = fractional distance of Moon's center to the Earth center, in lunar radii (negative for southward)
20. ra = Right ascension of Moon at greatest eclipse in hours
21. de = Declination of Moon at greatest eclipse in degrees north
22. p1 = Time of first contact with penumbral shadow (Beginning of partiality)
23. p2 = Time of last contact with penumbral shadow (Beginning of partiality)
24. u1 = Time of first contact with umbral shadow (Beginning of partiality)
25. u2 = Time of second contact with umbral shadow (Beginning of totality)
26. u3 = Time of third contact with umbral shadow (Ending of totality)
27. u4 = Time of forth contact with umbral shadow (Ending of partiality)
28. ch = NASA chart URL link
29. Tlast = wlink of previous total lunar eclipse
30. Tnext = wlink of next total lunar eclipse
31. Elast = wlink of previous lunar eclipse
32. Enext = wlink of next lunar eclipse
33. Slast = wlink of previous lunar eclipse of the same saros series
34. Snext = wlink of next lunar eclipse of the same saros series
