The Jicamarca Faraday mode data for the October MISETA observing period have been processed and made available through a new web page at
http://landau.phys.clemson.edu/faraday/faraday.html
This is an experimental web server that generates graphs of the density, temperature, and composition observations "on the fly" and allows a degree of online analysis. More new data will appear here as they are taken, as eventually will data from past MISETA experiments. Data can now be FTP'd directly from Jicamarca, processed, and added to the website on a next-day basis.
The data quality is quite high now, thanks to a major upgrade of the acquisition hardware and software undertaken recently by the Jicamarca staff. The new data have considerably smaller error bars than before and suffer from fewer dropouts. The observations from October 19th and 20th are contaminated by spread F, naturally, but the data from the 18th are quite clean.
The data from October 18th are the best ever obtained during this part of the solar cycle, thanks to a major upgrade to the data acquisition computer and software at Jicamarca. The accuracy of the experiment is now sufficient to go hunting for ~10 degree temperature variations at night, and indeed there seems to be a detectable postmidnight temperature enhancement visible in the data from the 18th. Also visible is an enormous undulation in the F layer height around the time in question. Data from other nights are obscured by the presence of spread F - we will have to wait for future experiments to see if this behavior is repeated.
