EXITING THE SOLAR WIND: Earth is exiting a stream of solar wind flowing from a hole in the sun's atmosphere. The day-long enhancement in solar wind velocity caused by this stream did little to spark geomagnetic activity. Better luck next time? Another stream of solar wind is due to arrive on July 19th.

PARTIAL ECLIPSE OF THE MOON: Tonight, when the Moon rose over Nynäshamn, Sweden, something was missing--that is, part of the Moon. Anders Jangö photographed the partial lunar eclipse over the Baltic Sea:
On July 16th, the full Moon passed through the shadow of Earth, plunging as much as 65% of the lunar disk into darkness. Sky watchers in Africa, Europe, Asia, Australia and South America saw at least part of the 3 hour eclipse. Only North Americans were excluded.
The next significant lunar eclipse won't happen until May 2021, so if you missed this one ... Mark your calendar.

APOLLO 11 ANNIVERSARY SILVER DOLLAR: The 50th anniversary of the Apollo 11 Moon landing is only days away. To mark the occasion, the students of Earth to Sky Calculus have been flying commemorative Apollo 11 silver dollars to the stratosphere and selling them to support their cosmic ray balloon program. Buy one this week and we will fly it to the stratosphere on July 20, 2019, exactly 50 years after Neil Armstrong set foot on the Moon.
We plan to fly only a small number of these coins to the edge of space on July 20, 2019. Reserve yours for $197.95.
Created by the US Mint, the proof-quality 99% silver dollar is curved and reproduces the helmet of astronaut Buzz Aldrin. Reflected in Buzz's visor are Neil Armstrong, the United States flag, and the lunar lander. The opposite side of the coin shows Neil's iconic footprint on the Moon. Each coin comes with a greeting card showing the item in flight on the 50th anniversary of the Moon landing and a certificate of authenticity.
