Lunar Report - 07/20/2020

By: Gordon Rutherford

Moon Phase Today: July 20, 2020
The Moon's current phase for today and tonight is a New Moon phase. During this phase the Moon is to close to the sun in the sky to be visible. The moon rises and sets with the sun and is not present in the night sky. Because of this the night sky is darker and an excellent time to view other celestial objects. Like the Full Moon, a New Moon happens at a very specific time when the sun and moon have the same ecliptic longitude and it can be measured down to the second it occurs.

Sturgeon Moon after 14 days

Next Full Moon is the Sturgeon Moon of August 2020 after 14 days on 3 August 2020 at 15:59.

Spring tide

There is high New Moon ocean tide today. Combined Sun and Moon gravitational tidal force working on Earth is strong, because of the Sun-Moon-Earth syzygy alignment.

Moon before perigee

7 days after point of apogee on 12 July 2020 at 19:27 in ♈ Aries. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 4 days, until it get to the point of next perigee on 25 July 2020 at 04:54 in ♎ Libra.

Distance to Moon 381 031 km

Moon is 381 031 km (236 762 mi) away from Earth on this date. Moon moves closer next 4 days until perigee, when Earth-Moon distance will reach 368 367 km (228 893 mi).

Moon after northern standstill

1 day after previous North standstill on 19 July 2020 at 11:51 in ♋ Cancer, when Moon has reached northern declination of ∠24.069°. Next 11 days the lunar orbit moves southward to face South declination of ∠-24.087° in the next southern standstill on 1 August 2020 at 08:47 in ♑ Capricorn.

Sun-Moon-Earth syzygy

The Moon is in New Moon geocentric conjunction with the Sun today and this alignment forms Sun-Moon-Earth syzygy.

Solar Activity

.24 hr Summary...
Solar activity was at very low levels under a spotless visible disk. No
Earth-directed CMEs were observed in available imagery.

Solar activity is expected to be at very low levels on 20-22 Jul.

Energetic Particles

.24 hr Summary...
The greater than 2 MeV electron flux reached moderate levels and the
greater than 10 MeV proton flux was steady at background levels.

The greater than 2 MeV electron and 10 MeV proton fluxes are expected to
remain below event thresholds on 20-22 Jul.

Solar Wind

.24 hr Summary...
The solar wind environment reflected background conditions.

Nominal solar wind parameters are anticipated on 20-22 Jul.


.24 hr Summary...
The geomagnetic field was quiet.

The geomagnetic field is expected to be at mostly quiet levels on 20-22
