Eclipse Monitoring 15th January 2010

by G. Victor A. Goonetilleke

From COLOMBO, Sri Lanka. As most people would know there was an Annular Eclipse of the Sun which was observed between South India and the Northern half of Sri Lanka. While many viewed the eclipse through shaded /smoked glass, Xray papers and many other devices, I viewed the eclipse from my home at Piliyandala (18km SE from Colombo) through the dials of my radio receiver, inside my shack with headphones on staring at the S-metre while scanning the Medium Wave and Shortwave frequencies below 7 MHz. My brother Ron 4S7RO and myself (4S7VK) made a similar observation somewhere in 1984 around 2.30 p.m. in the afternoon with tremendous results. Unfortunately, most of the stations that we observed on 2-7 MHz range, have now left short wave and thus there was very little to observe there. The 1984 Eclipse which ran across Central India gave us HF/SW signals from longer distances compared to the January 15th Eclipse which was only about 100 km north of Colombo. The problem with sky wave is that there is a dead zone between the ground wave and the first hop when we are so close to the eclipse.
