EY8ZF 2m EME digital QSO

Rene, PE1L and Frank, DL8YHR was active for only 2,5 moonpasses (27-04-2012 to 29-04-2012) in 2m EME (144.134) from Tajikistan with the call EY8ZF (locator MM48jn). The antennas was a 2X9 el. DF7KF  for 2m and 38 el. M2 single antenna for 432 Mhz.
They had a very good signal off the Moon and I would like to thank you both for the QSO and NEW ONE on 2m via EME.
The most important is that they slept only 1 hour after the 24 hours trip and start to build the antennas to be active as soon as posible.
Congratulations once again for nice job and for patience to stay every day from moonrise to moonset there on the radio.
Check the link below for foto colection from EY8ZF.
For more info about this EME dxpedition and new coming is here:
The Team gives BIG thanks to Nodir EY8MM for the great host of their activity.
The complete antenna set-up (inclunding power dividers and all cables) stays at EY8MM station for future activity.

Big Blast - April 16th 2012. FLARE and CME.
Look the video in YouTube.

On Monday, April 16 - 2012, NASA captured a huge eruption from the sun, accompanied by a solar flare and Coronal Mass Ejection (CME). Known as a prominence, such eruptions can extend many miles into space. Since this eruption was pointed away from Earth, the blast and accompanying mass ejection -- a cloud of charged particles often responsible for aurorae on Earth -- won't affect the home planet's atmosphere.
The sunspot continued to circle toward Earth though, with the potential for further eruptions, but the National Oceanic and Atmospheric Administration's Space Weather Prediction Center said Wednesday that the several eruptions pointing away from Earth may have put the sunspot region into a state of decay, making subsequent eruptions less likely.
This prominence eruption reached about 198,000 miles off the "surface" of the sun. The Earth is around 98 million miles away, so it wasn't even close. The frames were taken 36 seconds apart from each other; the actual event lasted several hours. The Solar Dynamics Observatory collected the images and they are in extreme ultraviolet. This red-colored wavelength is 304 angstroms, which shows plasma at around 50,000 Kelvin. You can't see this with the naked eye.
