Manila Observatory’s Ionosphere Division: Annual Report for 1996
I. INSTRUMENTATION A. Vertical Sounding The IPS-42 Digital Ionosonde replaced the C-3 analog film-recording ionosonde. The sweep frequency is from one to 15 MHz. the ionosphere directly overhead is probed twice a day. B. Trans-Equatorial or Oblique Ionosonde Signals transmitted across the equator from MO and received in several southern stations reveal the changing characteristics [...]

Upper Atmosphere Division (UAD): Mission and Vision
The Upper Atmosphere Division (UAD) of the Manila Observatory seeks to become an internationally respected Center for Space Weather Research in the Philippines. As a research division of the Manila Observatory, the UAD seeks to understand three things about the ionosphere: (1) its composition and variability, (2) its effect on the propagation of radio waves [...]

Strategic Planning at the Manila Observatory: Research directions for the Upper Atmosphere Division
Yesterday, after the Mass, Fr. Sergio Su, S.J. asked us to form groups of three and share our worries and hopes. I was with Dr. Gemma Narisma and Randell Teodoro. We made agreed on two points. First we get caught up in the issues and we forget what is it for and why are we [...]

Manila Observatory’s Ionosphere Division: Accomplishment Report for 1994
I. INSTRUMENTATION 1. Digital Ionosonde (IPS-42) and Geophysical Netweork Terminals (DBD-43) In Frebruary the Ionosonde and network Terminals were installed. The use of these new instruments resulted in the complete digitizing of ionograms. These ionograms are stored on digital data tapes instead of the usual use of films. For the first six months of the [...]

FM-CW radar breaks down during thunderstorms
Last May 9, 2009, the FM-CW (Frequency Modulated Continuous Wave) radar stopped sending data to Kyushu University. There was a lightning strike at the Manila Observatory at that time. The statue of St. Ignatius of Loyola in front of the Manila Observatory was nearly hit, putting many telephone lines out of service, including my telephone [...]

Magnetic dip equator and electrojets
What is an electrojet? Here is a wikipedia entry: “The equatorial electrojet (EEJ) is a narrow ribbon of current flowing eastward in the day time equatorial region of the Earth’s Ionosphere. The abnormally large amplitude of variations in the horizontal components in equatorial geomagnetic observatories, as a result of EEJ, was noticed as early as [...]
