Atmospheric seeing conditions for solar observing

Atmospheric Seeing Conditions

Reports and observations submitted to the AAVSO use the following ratings for atmospheric turbulence (Seeing): Poor, Fair, Good and Excellent.

Solar Reporting Form

SOLAR REPORTING FORM


The sunspot reporting form below has been created with a variation of the SUNKEY.exe program
and embodies the information and column/character alignments required by the AAVSO Solar
Division data processing software. It can be used by any observer who has previously sent an
email report to the Division using SUNKEY.exe or the regular-mail paper report. OBSERVERS WHO
ARE REPORTING FOR THE FIRST TIME SHOULD USE EITHER THE SUNKEY.EXE PROGRAM AVAILABLE ON THIS
WEBSITE OR THE REGULAR MAIL FORM SO THAT IMPORTANT INFORMATION REGARDING ADDRESS AND TELESCOPE

Sunkey Readme File

The program SUNKEY enables you to enter your sunspot data
directly into your computer.  It will run on almost any PC
operating system, including DOS, Windows 3.1, Win95, and
Win98.

To install the program, first choose a folder (directory)
where you wish to keep your sunspot data.  You may wish to
create a new folder (directory) specifically for this
purpose.  Then copy the file SUNKEY.EXE into that folder
(directory).

If you operate under DOS, installation is complete.  To run

SID Program - Reducing Data and Email Format

Reducing Data Gathered by VLF Monitoring Systems

(Extracted from SID Technical Bulletin Vol. 3, Number 4, Oct. 1992)

The reduction process is quite simple, and consists of the steps which follow. First, the universal time for each of three event-phases must be measured for each SID. Examples are indicated on the recording at the end of this report.

SID Data Report Format

The AAVSO SID section provides a number of options for data logging, data reduction and report generation. You may or may not use one or all of these methods. How you monitor SIDs and how you generate a report is up to you and left open to personal preference. The only constraint imposed by the SID Program as a requirement for submitting data is the format of that data. Two requirements must be met. One is the internal format and the second is the file name convention of the formatted report.
