Notes: All timings are represented in 24+ hour notation in local time of Ashburn, United States with DST adjustment (if applicable).
Hours past midnight are higher than 24:00 and fall on next day. In Panchang day starts and ends with sunrise.
Partial Lunar Eclipse would occur on June 04, 2012. The Moon will be about one third covered by the Earth's Umbral shadow at maximum eclipse. The portion of the moon inside the Umbral shadow will only be illuminated by sunlight refracted through the Earth's atmosphere and having a reddish hue.
If Lunar Eclipse starts before midnight but ends after midnight i.e. it covers two different dates on Gregorian calendar then the chosen Eclipse Day is when maximum of Lunar Eclipse occurs. Hence Penumbral Phase as well as Umbral Phase might start before midnight i.e. on the previous day.
Moonrise and Moonset moments are corrected for Parallax and this correction gives better timings for the Eclipse sighting.
Unless Lunar Eclipse is visible to the naked eye, it is of no significance to Hindus and Hindus don't consider it for any religious activities. Penumbral Lunar Eclipses are not visible to the naked eye hence no rituals related to Chandra Grahan should be observed. If Lunar Eclipse is visible during Umbral Phase then only it should be considered for religious activities. Most Hindu Calendars don't list Penumbral Eclipses.
If Chandra Grahan is not visible in your city but it is visible some city near to that then you should not observe it. Precautions which are advised during Sutak should be taken only if Chandra Grahan is visible in your city. Chandra Grahan is considered even if the Moon is not visible due to cloudy weather or some other weather conditions.
