On Thursday, February 19th, 2015, the Moon in full and are in a state of its closest point to Earth. However, unfortunately, the phenomenon known as 'Supermoon' it can not be seen by humans, so this event dubbed 'Ghost Supermoon'.
The Moon will be in the closest point to the Earth (extreme perigee) at 02:00 ET or 14:00 pm Western Indonesian Time. The distance to the Earth ranges 221,826 miles or 356.994 km - only 117 km farther than Supermoon on September 27, 2015 - in which the moon will look bigger and brighter in the night sky.

The reason of why the skywatchers could not see it, because the new Moon and the position of the Moon is too close to the Sun, so she did not appear and the phenomenon also happens to occur in the daytime sky.
Does the Moon - which though invisible - was at the closest point to the Earth, will cause effects on our planet? As quoted from SPACE, the answer is yes. One of them could trigger a high tide, as will accompany the September Supermoon phenomenon.
Because that happened in February was a new moon. Thus, the position of the Earth, Moon, and Sun relative to form a straight line. Those alignments will trigger what is called 'spring tides' - which occurs when the Sun mingled fascination with the Moon's gravity - which resulted in a higher tide than usual.
Spring tide occurs 2 times a month, around the time of the new moon or full moon. The term of 'spring' has nothing to do with the spring - in English. But taken from German, 'entspringen', which means 'rose'.
Full tide associated with the new moon will cause higher than normal tide and low tide levels will be lower than normal. It happened because the perigee (the approach events of the Moon to the Earth) occurred more than seven hours after the new moon. The new moon this time it will be closer 12.2 percent while perigee than the full moon on March 5, 2015.
And this new moon will trigger tidal more than 42 percent during the full moon tide on February 19 compared which happened on 2 weeks ago. "So, although could not see the Supermoon, for those who living on the coast will see its signs through the tide that occur at the time, or within a few days after the February 19, 2015," said Joe Rao, an instructor at New York's Hayden Planetarium, as published by SPACE. *** [EKA | FROM VARIOUS SORCES | SPACE]
