Today's Moon phase for 27 July 2020 
First Quarter 50% illuminated

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 7 days

* The exact date and time of this First Quarter phase is on 27 July 2020 at 12:32 UTC.

Neap tide
There is low ocean tide today. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

Moon after perigee
2 days after point of perigee on 25 July 2020 at 04:54 in ♎ Libra. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 13 days, until it get to the point of next apogee on 9 August 2020 at 13:51 in ♈ Aries.

Moon is 363 879 km (226 104 mi) away from Earth on this date. Moon moves farther next 13 days until apogee, when Earth-Moon distance will reach 404 658 km (251 443 mi).

Moon before southern standstill

8 days after previous North standstill on 19 July 2020 at 11:51 in ♋ Cancer, when Moon has reached northern declination of ∠24.069°. Next 4 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.

Syzygy in 7 days
After 7 days on 3 August 2020 at 15:59 in ♒ Aquarius, the Moon will be in Full Moon geocentric opposition with the Sun and this alignment forms next Sun-Earth-Moon syzygy.

Solar Activity
24 hr Summary
Solar activity was very low. Region 2767 (S20W01, Hsx/alpha) was quiet and stable. No Earth-directed CMEs were observed in available imagery.

Forecast Solar activity is expected to remain at very low levels on 27-29 Jul. Energetic Particles .24 hr Summary The greater than 2 MeV electron flux reached moderate levels and the greater than 10 MeV proton flux remained at background levels.

Forecast The greater than 2 MeV electron and 10 MeV proton fluxes are expected toremain below event thresholds on 27-29 Jul.

Solar Wind
24 hr Summary
Solar wind parameters, as measured by the DSCOVR spacecraft, reflected nominal conditions. Total magnetic field strength was at or below 5 nT. Solar wind speeds were between 357-427 km/s. Phi angle was oriented in the negative sector.

Forecast The solar wind environment is expected to continue at nominal levels on 27 Jul. A weak enhancement is anticipated on 28-29 Jul as a negative polarity CH HSS becomes geoeffective.
Geospace 24 hr Summary... The geomagnetic field was quiet.

The geomagnetic field is expected to be at mostly quiet levels on 27Jul. Quiet to unsettled levels are expected on 28-29 Jul due to the anticipated onset of CH HSS influence.
