Observation Trip 10 -19 -18 Observers: Gary Agranat, Paul Berge Richard Russel Receiver: Spectra. Cyber with 1420 Mhz. Cavity Filter on 60 -foot dish Pointing System: System 1 Goals: 1) Take Milky Way rotation rate data 2) Observe sources with known Jansky signal levels to determine if a signal calibration level can be estimated

B: 10 Time/Step: 0. 25 Note: We started with Upper KHz at + 500 and Lower KHz at -500 however we started getting sources with high Doppler so we shifted to +-800 Khz

Galactic Rotation Rate Observations • Observe the Galactic Plane at Galactic Latitude 0 and Galactic Longitudes 0, 10, 20, 30, 40, 50, 60, 70, 80, and 90 degrees. This maps the Milky Way’s quadrant 1 • Determine the highest Doppler rate of each measurement • Calculate distance to the observed source using the tangent method • Calculate the velocity of the observed source at the calculated distance • The final result is a plot of the Milky Way’s rotation rate at different distances from the galactic center

Summary • The Milky Way Rotation Rate looks promising and is close to reported curves from numerous sources. • Plan is to do at least two more rounds of observations in order to verify results • Calibration data was inconsistent • Possible issue is the use of 1950 vs 2000 RA/DEC position data • Plan is to update all 1950 positions to the 2000 positions and to retake the data • It is possible that the 60 ft. dish elevation pointing may not be calibrated due to the RF pointing changing based on the elevation angle of the dish – plan is to try to get some elevation pointing calibration data
