SDO and Ham Radio


There are a few good websites for up to date solar data.  Being a ham radio operator I am among a community whose hobby is very dependent on what the Sun is doing.  One of the best sites around is from a Canadian Amateur Radio Station VE3EN called SolarHam.

Check out the video of this event from SDO/NASA.

From the Solar Dynamics Observatory:

One active region at the edge of the Sun pushed out about ten thrusts of plasma in just over a day long period (July 9-10, 2016). All of them, propelled by magnetic forces, quickly withdrew back into the active region. The images were taken in a wavelength of extreme ultraviolet light.

Venus Express Science


We a bit more science from Venus and the Venus Express. I should note up-front gravity waves are NOT the same as gravitational waves

The ESA introduction:
Schematic illustration of the proposed behaviour of gravity waves in the vicinity of mountainous terrain on Venus.

Winds pushing their way slowly across the mountainous slopes on the surface generate gravity waves – an atmospheric phenomenon also often seen in mountainous parts of Earth’s surface. These waves form when air ripples over bumpy surfaces. The waves then propagate vertically upwards, growing larger and larger in amplitude until they break just below the cloud-top, like sea waves on a shoreline. As the waves break, they push back against the fast-moving high-altitude winds and slow them down.

Now for the whole story.

Progress Cargo Ship Leaves Port

The Russian Progress 64 leaves the Baikonur Cosmodrome in Kazakhstan, heading for the International Space Station on 16 July. The cargo ship contains carrying three tons of food, fuel and supplies for the station.

The arrival will be in 18 July which is incidentally the same date as a SpaceX rocket will be launching to the ISS. The Dragon cargo ship will transport crew supplies and station hardware including the first of two new international docking adapters. The adapters will allow for docking both the SpaceX CREW Dragon and Boeing’s CST-100 Starliner and will bring back the American ability to transport astronauts to the ISS, an ability lacking since the end of the Space Shuttle era.

The SpaceX launch is scheduled for 04:45 UTC / 00:45 EDT on 18 March. The weather looks good, check back for a live look later.

UPDATE:  Check back here for a LIVE link to the launch posting at 04:00 UTC.



WT1190F is a ‘real-world’ example of how NASA’s Planetary Defense Coordination Office along with contributers around the world is keeping an eye on what is sharing our space.
