Partial solar eclipse on 2015-03-20 in Moheda, Sweden, JO77GA.

Kjell, SM7GVF.

Measurements were performed on 144 MHz with 4x8 elements at 23 magl. The sun noise+noise to cold sky+noise is only around 2 dB on this system.
I suspect the antennas are not working properly (VSWR).

The recording started a bit late. I am afraid results could be compromised by external noise sources and temperature drift, as always.


Above is shown relative sun noise+noise over time. The scale to the left is in dB, time is UTC+1. Measured with Noise Meter program in
SSB bandwidth on a TS2000 with AGC reduced. System NF (LNA+coax) is around 1.5 dB.

Lowest noise appeared at 10:03 UTC.

, time is UTC. Two measurements to cold sky (at 10:30 and 11:53) were performed.

According to this site, http://www.astroinfo.se/articles/243/2015-03-20-stor-partiell-solfoermoerkelse-mitt-pa-dagen, the partial eclipse
should have occurred at 09:54 UTC at my location, and the sun should have been blocked to 81 %.

Data from http://eclipse.gsfc.nasa.gov/SEgoogle/SEgoogle2001/SE2015Mar20Tgoogle.html below show the same.

Updated 2015-02-20 17:48 UTC with that I suspect the antennas are not working properly.
