Lunar Report - 09/03/2017

By:  Gordon Rutherford

Date and time:3 September 2017 - 10:37MST
Moon distance to earth:247,004 miles
Age moon:12.3 days
Moon phase:Size of moon increases
Percentage visible:93%

The Moon today is 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 it’s roots in the Latin word "gibbosus" meaning humpbacked.

Upcoming main Moon phases
Full Moon in 2 days on 6 September 2017 at 07:03
Last Quarter in 9 days on 13 September 2017 at 06:25
New Moon 16 days on 20 September 2017 at 05:30
First Quarter in 24 days on 28 September 2017 at 02:54

Moon before descending node
13 days after its ascending node on 21 August 2017 at 10:34 in ♌ Leo, the Moon is following the northern part of its orbit for the next day, until it will cross the ecliptic from North to South in descending node on 4 September 2017 at 18:41 in ♒ Aquarius.

Moon after southern standstill
2 days after previous South standstill on 1 September 2017 at 02:03 in ♑ Capricorn, when Moon has reached southern declination of ∠-19.393°. Next 11 days the lunar orbit moves northward to face North declination of ∠19.438° in the next northern standstill on 14 September 2017 at 13:00 in ♋ Cancer.

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.

Tropic of Cancer Tide Times
  • Low 01:31am
  • High 07:28am
  • Low 01:45pm
  • High 08:03pm

Harvest Moon (FULL MOON) - after 2 days
Next Full Moon is the Harvest Moon of September 2017 after 2 days on 6 September 2017 at 07:03.

Moon after apogee
4 days after point of apogee on 30 August 2017 at 11:25 in ♐ Sagittarius. The lunar orbit is getting closer, while the Moon is moving inward the Earth. It will keep this direction for the next 10 days, until it get to the point of next perigee on 13 September 2017 at 16:04 in ♊ Gemini.

Solar Wind (24 hr Summary)
Solar wind parameters indicated continued influence from a positive polarity CH HSS. Solar wind speeds began the period near 650 km/s and gradually declined to end the period near 500 km/s. Total field (Bt) ranged between 1 and 5 nT while the Bz component did not drop below -3 nT. Phi angle was positive.

The solar wind environment is expected to remained enhanced for the next three days (03-05 Sep) due to ongoing, but slowly waning, CH HSS effects.

Solar Activity (24 hr Summary)
Solar activity was at low levels. The strongest event of the period was a C7 flare observed at 02/1541 UTC from around the W limb. Associated with the flare was a Type II radio burst (estimated speed 976 km/s) and a CME signature which is not expected to be Earth-directed. Region 2674 (N14E18, Fhc/beta-gamma) displayed minor growth in its intermediate spots and produced a single low level C-class flare during the period. The remaining numbered sunspots were absent of flare activity. There were no Earth-directed CMEs observed in available satellite imagery.

Solar activity is expected to be at low levels with a slight chance for M-flares (R1-R2, Minor-Moderate) over the next three days (03-05 Sep).

Energetic Particles (24 hr Summary)
The greater than 2 MeV electron flux was at moderate to high levels with a maximum flux of 7,573 pfu observed at 02/1740 UTC. The greater than 10 MeV proton flux continued at background values.

The greater than 2 MeV electron flux is expected to continue at moderate to high levels on days one through three (03-05 Sep). The greater than 10 MeV proton flux is expected to continue at background levels.

X-Ray Flux (Last 3 days)

Geospace (24 hr Summary)
The geomagnetic field was at quiet to unsettled levels due to continued CH HSS influence.

The geomagnetic field is expected to be at quiet to unsettled levels, with an isolated period of active conditions, on day one (03 Sep) as CH HSS influence continues. Quiet to unsettled levels are expected on days two and three (04-05 Sep) as influence from the CH HSS wanes.
