TODAY - July 31, 2020

Waxing Gibbous 89% illuminated

Today the Moon will be in a Waxing Gibbous phase. This phase is when the moon is more than 50% illuminated but not yet a Full Moon. The phase lasts round 7 days with the moon becoming more illuminated each day until the Full Moon. During a Waxing Gibbous the moon will rise in the east in mid-afternoon and will be high in the eastern sky at sunset. The moon is then visible though most of the night sky setting a few hour before sunrise. The word Gibbous first appeared in the 14th century and has its roots in the Latin word "gibbosus" meaning humpbacked.

Sturgeon Moon after 3 days

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

Syzygy in 3 days

After 3 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.

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

6 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 9 days, until it get to the point of next apogee on 9 August 2020 at 13:51 in ♈ Aries.

Distance to Moon 376 116 km

Moon is 376 116 km (233 708 mi) away from Earth on this date. Moon moves farther next 9 days until apogee, when Earth-Moon distance will reach 404 658 km (251 443 mi).

Moon before southern standstill

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

Product: Forecast Discussion

Solar Activity


24 hr Summary
Solar activity was very low. Both Region 2767 (S20W46, Hsx/alpha) and Region 2768 (N26E40, Hsx/alpha) were mostly quiet and exhibited signs of weak decay. No Earth-directed CMEs were observed in available imagery.

Forecast
Solar activity is expected to remain at very low levels for the next three days.

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 to remain below event threshold for the next three days.

Solar Wind


24 hr Summary
Solar wind parameters, as measured by the DSCOVR spacecraft, continued to reflect nominal conditions. Total field strength averaged near 5 nT and the Bz component saw a maximum southward deflection to - 7 nT. Solar wind speeds were between 315 and 330 km/s. Phi angle rotated between both phi angle orientations.


Forecast
The solar wind environment is expected to continue at nominal levels for 31 Jul. 01-02 Aug may see enhancements consistent with a recurrent positive polarity CH HSS.

Geospace


24 hr Summary
The geomagnetic field was quiet.


Forecast
The geomagnetic field is expected to be quiet for 31 Jul and quiet to unsettled on 01-02 Aug due to possible CH HSS impacts.
