MARS Image file 2001-09-02-TJR INSTRUMENTAL 180mm Astro-Physics EDT apochromatic refractor SBIG ST7e CCD camera 0.35 arcsec/pixel IMAGING 2001-Sep-02, 11:04 UT 17 of 64 exposures, 0.11sec, R filter. Camera temp -26oC Dark & flat calibrated CONDITIONS Ambient temp=11C Seeing 5/10, Transparency 4/5. Mars's altitude 65o. MARS DATA CM=320o, Diam=13.2", Ph=86%, PAdef=90o, PAaxis=28o. South up. REMARKS Visually with red filter there was a suggestion of Syrtis Major and Hellas. The R image shows Syrtis Major with Libya and Iapygia near the limb. Further N, Hellas is large and bright. The fork where Mare Serpentis and Sinus Sabaeus meet is near the terminator. No sign of polar caps/hoods. Dr Tom Richards, Woodridge Observatory, Melbourne Australia tom@woodridgeobsy.org

Eyepiece Projection @ f/44.2
Integration Times:
BLUE (Koheisha, 445nm peak central; BWHM 105nm) 2.32-5.20s
GREEN (Koheisha, 540nm peak central; BWHM 75nm) 0.72-1.60s
RED (RG610 - No IR Rejection) 0.16-0.34s
Images flat and dark corrected.
Seeing fairly good (7-8, Pickering) Transparency variable (3-5m) due to high
cirrus and fast cumulus. Wind gusty, NE-ENE 2-10 kts. Altitude = 35 degrees.
No dew.
Visibility of albedo features improving; western Sirenum M., Titanum S., and
Gigantum S. seen. Poss streak in Daedalia. Olympus Mons visible.
Bright PM limb arc extending over SPR. Possible glimpse of SPC. NP hood
remains weak.

Seeing good (7-8, Pickering) despite frequent rain clouds. Transparency
variable (3-5m). Wind gusty, ENE 0-9 kts. Altitude = 37-36 degrees.
No dew.
Bright dust clouds continue to erupt in Solis Planitia. Bright cloud over
Solis LAcus centered approx. 90W, 25N. -- also bright in green. In
addition, Sirenum S. very faint, with dust clouds noted in Phaethontis
extending eastward, obscuring Aonius Sinus. Phoenicis L. very dark. Phasis
(?) noted.
The four great Tharsis volcanoes again prominent. SPC very small, while NP
Hood remains small, disorganized. Bright PM limb haze persists.

Hellas bright, yellowish with bright white streak along southern rim. Some
detail visible on Hellas' floor. The other albedo features are more distinct
than in the past two months. Syrtis Major thin, with Moeris Lacus and
Nymphaeum Pr. both prominent. Tyrhennum M. and Syrtis Minor very dark.
E. limb haze persists; NP Hood largely absent. SPC small bright, both
visually and on CCD images.
