Some predictions on the options to observe the lunar crescent around conjunction on 22. June 2009 from Jeddah, using the established contrast-enhancing techniques and assuming good conditions.
All times are UT.
|22. June||01:45|| Moon rises at 10° elongation, azimuth 61°, 45 minutes before sunrise, Sun at -10° altitude: |
Should be possible to observe through traditional observation
|22. June||02:30|| Sun rises, Moon is at 9.6° elongation: |
Daytime observation can begin, with ever decreasing distance untill sunset
|22. June||16:09||Moon sets, shortly before the sun, at 3.7° elongation|
|22. June||19:35||Geocentric conjunction at 1.85° elongation: invisible as both bodies have set|
|23. June||02:50|| Moon rises, some 20 minutes after the sun, at 5.5° elongation: |
Daytime observation can begin, at ever increasing distances untill sunset
|23. June||16:16|| Sun sets, moon at 11.4° elongation, azimut 292°: |
Traditional observation should be possible before moonset
|23. June||17:09||Moon sets, at 11.9° elongation, Sun at -11° altitude|
|Mercury is 20° west of the sun at -0.3mag|
|Venus is 45° west at -4.2mag|
|Castor is 22° east of the sun at 1.2mag|
