The Philippines' most active volcano shot higher ash columns and rumbled louder on Wednesday as authorities warned of a potential hazardous eruption in Mount Mayon anytime. Mayon Volcano, known for its near-perfect cone shape in the coconut-growing central Bicol region, has been spewing ash and burning mud and rocks for more than a week. Officials have evacuated nearly 50,000 residents from around the base of the volcano. President Gloria Macapagal Arroyo flew on Wednesday to Albay province where Mayon Volcano is located to inspect the government's disaster preparedness plan. She briefly talked to some of the evacuees and handed out relief goods. Authorities said they monitored distinct indicators of a hazardous eruption, such as continuous lava flows, rumbling sounds and ash explosions coupled with sulphuric dioxide emission from the volcano.

I can not help as to wonder who took my photo and why. I how ever did see my photo being used by other hams as their own personal shack. That really pisses me off.
I have a guest book, please let me know why you needed my image. Leave a comment on the original post or this one. Maybe I should post the IP address of all those that stole my image. Then again, who really cares? It is my shack and no one can claim it other then my XYL.
HOW TO READ PROPAGATION NUMBERS
The A index [ LOW is GOOD ]
- 1 to 6 is BEST
- 7 to 9 is OK
- 11 or more is BAD
Represents the overall geomagnetic condition of the ionosphere ("Ap" if averaged from the Kp-Index) (an average of the eight 3-hour K-Indices) ('A' referring to amplitude) over a given 24 hour period, ranging (linearly) typically from 1-100 but theoretically up to 400.
A lower A-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Ap-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.
SFI index [ HIGH is GOOD ]
- 70 NOT GOOD
- 80 GOOD
- 90 BETTER
- 100+ BEST
The measure of total radio emissions from the sun at 10.7cm (2800 MHz), on a scale of 60 (no sunspots) to 300, generally corresponding to the sunspot level, but being too low in energy to cause ionization, not related to the ionization level of the Ionosphere.
Higher Solar Flux generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; Solar Flux rarely affects the 30, 40, 60, 80, & 160 Meter Bands.
K index [ LOW is GOOD ]
- 0 or 1 is BEST
- 2 is OK
- 3 or more is BAD
- 5 is VERY VERY BAD
The overall geomagnetic condition of the ionosphere ("Kp" if averaged over the planet) over the past 3 hours, measured by 13 magnetometers between 46 & 63 degrees of latitude, and ranging quasi-logarithmically from 0-9. Designed to detect solar particle radiation by its magnetic effect. A higher K-index generally means worse HF conditions.
A lower K-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Kp-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.
