New Milky Way H Map – Incredible Detail

Sky & Telescope has a short, illustrated news item today about high resolution 1H (atomic hydrogen) observations of our galaxy from Australia and Germany. It includes a video showing how the view changes with wavelength due to Doppler shift. I thought this would be good to share; this is what we’ll be looking for with the HI drift scans.

Plishner Perseids Meteor Shower Expedition 12-13 August 2016

DSES will have its first major observing expedition at the Plishner site on 12 – 13 August in conjunction with the Perseid Meteor Shower.

The following radio telescopes will be set up for observing:
1) Hydrogen – on 60 ft dish using Ray’s new feed
2) Radio Jove
3) Meteor Scatter
4) SuperSIDS
5) Itty Bitty Telescope

Also a number of optical telescopes will be set up to watch the meteor shower + planet and star observations.
We are also trying to get a solar telescope to do some daytime observations.

Ham radio operators will use the new DSES Club call sign, K0PRT, to make radio contacts. We will have HF antennas plus SHF, UHF, and VHF using the 60 ft dish available.

The setup team will arrive about 1200 on the 12th and start observations around 1700 and throughout the night. Observers should bring thumb drives and observer journals.

Anyone participating should bring sleeping gear and food for the overnight event. The clearing next to the communications van will be available for camping or campers. Recommend anyone sleeping in the bunker bring a cot and sleeping bag.

The event will end at 1600 on 13 August.

Please RSVP to Rich Russel.
