New moon Supermoon, Total Solar Eclipse, spring tides

A new moon Supermoon will black out the sun in Indonesia, currently in the news for strong earthquakes and volcanic eruptions almost daily.


The activity of the volcano seems to have picked up. Sinabung increases its activity after the big pyroclastic flow on 26 Feb which burned the remaining houses left from the previous damaged village (Simacem)...- this and the occurrence of highly hybrid tremors means there is deformation of the lava dome that grows continuously and increases the intensity of rock falls followed by pyroclastic flows." - VolcanoDiscovery


Total solar eclipse to sweep across Indonesia

The phenomenon, which occurs when the moon moves directly between the earth and sun, begins at 6:20 AM Wednesday, March 9 local time (11:20 PM GMT Tuesday, March 8).
According to NASA, the moon will black out the sun over Indonesia's main western island of Sumatra, before moving across Sulawesi and Borneo, and then over to the Maluku Islands. - CNN
First of year’s 6 supermoons March 9
We’ll have six supermoons in 2016. Depending on your time zone, the first of the bunch is to fall on March 8 or 9, 2016. Moreover, this upcoming supermoon will totally cover over the sun’s disk, to stage a total solar eclipse over Indonesia during the morning hours on March 9, and a partial solar eclipse for Hawaii and Alaska in the late afternoon on March 8. By the time you read this post, it’s possible the eclipse will be over. Its maximum point comes at 01:59 UTC on March 9, 2016 … that is, during the night of March 8 for those in the contiguous United States.

Likewise, the new moon supermoon comes during the night of March 8 for those in contiguous U.S. timezones. What, you say? Supermoon? But the moon isn’t anywhere near full on this date! That’s right. This isn’t a full supermoon. Rather, it’s a new supermoon

Spring tides accompany March 2016’s supermoon. Will the tides be larger than usual at the March, April and May new moons? Yes, all new moons (and full moons) combine with the sun to create larger-than-usual tides, but perigee new moons (or perigee full moons) elevate the tides even more.

The March 9 extra-close new moon will accentuate the spring tide, giving rise to what’s called a perigean spring tide. If you live along an ocean coastline, watch for high tides caused by the March, April and May 2016 new moons – or supermoons.

Will these high tides cause flooding? Probably not, unless a strong weather system accompanies the perigean spring tide. Still, keep an eye on the weather, because storms do have a large potential to accentuate perigean spring tides. - EarthSky


Around each new moon (left) and full moon (right) – when the sun, Earth, and moon are located more or less on a line in space – the range between high and low tides is greatest. These are called spring tides. Image via physicalgeography.net
