Moon Phase Today: July 29, 2020
Waxing Gibbous 72% illuminated

The Moon's current phase for today and tonight is 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 5 days

Next Full Moon is the Sturgeon Moon of August 2020 after 5 days on 3 August 2020 at 15:59.

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
4 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 11 days, until it get to the point of next apogee on 9 August 2020 at 13:51 in ♈ Aries.

Distance to Moon 368 310 km
Moon is 368 310 km (228 857 mi) away from Earth on this date. Moon moves farther next 11 days until apogee, when Earth-Moon distance will reach 404 658 km (251 443 mi).

Moon before southern standstill

10 days after previous North standstill on 19 July 2020 at 11:51 in ♋ Cancer, when Moon has reached northern declination of ∠24.069°. Next 2 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 5 days
After 5 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 (S21W21, Hsx/alpha) remained quiescent. No Earth-directed CMEs were observed in available imagery.

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.

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, reflected nominal conditions. Total field strength averaged near 4 nT, the Bz component ranged from +/- 5 nT, and solar wind speeds were between 350-440 km/s. Phi angle remained mostly oriented in the negative sector.

The solar wind environment is expected to continue at nominal levels for the next three days.

24 hr Summary
The geomagnetic field was quiet.

The geomagnetic field is expected to be quiet for the next three days.
