Altrock (USAF/PL) works on solar-cycle studies of the solar corona,
using data from the SP Emission-Line Coronal Photometer (ELCP). This
includes investigation of the variation of activity and rotation as
a function of latitude and various periodicities in activity. Efforts
to understand the implications of and to refine knowledge of
overlapping solar cycles as observed in the corona will be continued.
Studies of the variation of Fe XIV and Fe X coronal flux and their
relationship to other global solar parameters will be performed. ELCP
data will be searched for transients, and correlations with
chromospheric, upper-corona (from space-based instruments), and
possibly solar-wind and geomagnetic data will be investigated.
Investigations of the spatial and temporal variations of coronal
temperature will continue. Correlations will be performed on East-limb
ELCP Ca XV intensities and flare intensities of associated active
regions during their disk passage. Studies of the relationship of
coronal hole properties to solar wind speed will be carried out.
Altrock tracks the effects of pollution on Sac Peak skies. He is a member of the NASA working group: The Thermosphere, Thermal Environment and Solar Conditions Working Group of the Space Environment and Effects Program. He is the manager of the Emission-Line Coronal Photometer (ELCP) synoptic program. He supervises Tim Henry, data assistant and programmer, for this project. He continues to manage the CORONALERTS worldwide alerting system for unusual activity in the solar corona. Daily data products continue to be faxed to the NOAA Space Environment Services Center and the Air Force 50th Weather Squadron. Altrock participates in AURA activities such as membership on the NSO/SP Telescope Allocation Committee and providing coronal data to the community on the NSO/SP anonymous FTP site and automatically by email. He supplies coronal data to NOAA for publication in Solar Geophysical Data.
