Notes:
11:00 U.T. (left image): A drawing of Mars made using a red (Wratten
23A) filter. The North Polar Cap (NPC) is small and brilliant along
the north polar limb. The NPC appears to be surrounded by a dark
to dusky (3-4/10) collar consisting of Scandia, Lemuria, and Panchaia.
The region between Diacria and Trivium Charontis appears as a mottled
dark to dusky (3-4/10) complex which includes Azania, Hades, and Phlegra.
The Amazonis-Arcadia region appears dusky to dull (4-5/10) towards
the preceding limb adjacent to an extremely bright (9/10) evening limb
haze and cloud. An extremely bright (9/10) cloud appears over the
western (following) half of Elysium. Mare Sirenum and Mare Cimmerium
appear dark (3/10) towards the southern limb separated by a thin, dull
(5/10) strip (Atlantis I and II). An extremely bright (9/10)
southern limb haze (SLH) and morning limb haze (MLH) is noted as well.
Integration Times: BLUE (Koheisha, 445nm peak central; BWHM
105nm) 0.95s 11:15 U.T. (right image): A drawing of Mars made
using blue (W38A) and blue-green (W64) filters. The disk is encircled
by an extremely bright (9/10) haze over the preceding (evening
limb haze (ELH)), southern (SLH), following (morning limb haze (MLH)),
and northern limbs. A Violet Clearing (or Blue (W38A)) of 0-1 was
noted at this time (Mare Sirenum, Scandia, Diacria, and Panchaia).

INFORMATION FOR MARS OBSERVATION, MARCH 8th, 2001. D. A. Peach, King's Lynn, Norfolk, UK. 12" (30.5cm) Meade SCT. Magnifications: 406X. Filters: Unfiltered/W#21. Seeing very poor (2-3 at 15degs altitude.) Seeing good (6-7) at ~50 degs altitude.Transparency good (4.0mag), high haze, cirrus. Wind SE (0-5mph.) Light dew. Observation Time: 04:40 - 04:55 UT Mars CML: 65.6 Ls: 127.4 Diameter: 8.29" Altitude of Mars: 15degs. Comments: Seeing at this altitude was poor on this occasion, seriously limiting the view. Despite this a distinct haze over Chryse was observed. Also, prominent Olympus Mons cloud on the Morning Limb. Haze also visible over Argyre I. NPC quite small, but still visible. around local noon. Very weak to no terminator hazes. Mare Acidalium/Erythraeum visible, but rather deviod of fine details due to seeing. Solis Lacus faint, again due to seeing. Nilokeras also faint. Images flat and dark corrected. Seeing POOR (4, Pickering). Transparency GOOD (4.5m)]

Caption: It is rather cold for March, sometimes the wind blows hard. Hellas is extremely bright especially in blue images. Dark spot in the center of Hellas - Zea Lacus? - is noted in R images [R2]. Syrtis Major is very dark [R2]. Syrtis Majpr, Aeria, and Arabia is covered with blue cloud [B2], [B3]. Arabia is bright also in R image [R2]. Cecropia and Boreosyrtis is faint.

2001/03/24, 9:01 UT, Bowie MD, 20-inch f/6.4 reflector 200x: Seeing 4 out of 10. Very poor seeing. Air temp. of 38 degrees F, Saturday morning, about 4am. 20mm Pretoria. Any more power useless in the poor seeing. Small 9" disk! Hellas easy, some darkening that must be Mare Serpentis/Sinus Sabaeus. Chryse very bright. White clouds over Syrtis Major.
