CHr uses filters Wr23A (for red), Wr38A (for blue) and Wr64 (green-blue).
The sketch on 6 Jan (061°Ls) at ω=036°W was made in colour; the morning side being very white, while Tempe is orange. The following are sets of drawings in red and those in blue up until the end of March. The ω here recorded depends on the red one. The blue drawing is behind about 30 minutes and so.
Now on 29 Jan (071°Ls) at ω=132°W, Solis L appeared dark while Thaumasia looked dusty to CHr as stated in his LtE cited in #184 p1995. Apparent diameter δ=10.4".
On 5 Feb (074°Ls) at ω=035°W, M Acidalium was partially misted in the morning.
On 7 Feb at ω=045°W, Solis L was already caught.
On 13 Feb (078°Ls) at ω=340°W, the evening terminator was bright but Syrtis Mj was still seen. M Acidalium was totally inside the disk.
On 20 Feb (081°Ls) at ω=270°W, Elysium was bright near the evening terminator. N Alcyonius evident. The contour of the npc was not clear.
On 24 Feb (083°Ls) at ω=237°W, the EBC looked to be seen, though Syrtis Mj was considerablly apparent.
On 28 Feb (084°Ls) at ω=194°W, Propontis I very evident and Elysium bright.
On 4 Mar (086°Ls) at ω=156°W, Olympus Mons roundish bright even in red and a faint interesting dark marking preceded it near the terminator. See the drawing cited in another column.
On 7 Mar (087°Ls) at ω=120°W, Olympus Mons at the CM. M Acidalium near the terminator from which a mist extended west-southward.
On 10 Mar (087°Ls) at ω=108°W, Tharsis bright in the evening, and independently Olympus Mons roundish (one hour later Ascraeus Mons was detected in blue).
On 17 Mar (092°Ls) at ω=033°W, M Acidalium near the CM while Hyperboreus L was not well separated though dark.
On 22 May (122°Ls) at ω=126°W, the npc already thin in SN (De φ=25°N).
On 3 June at ω=030°W, Chryse was light on the morning side.
On 6 June (129°Ls) at ω=341°W, Syrtis Mj still big and Ismenius L was seen near CM to the north. The npc thin.
On 16 June (134°Ls) at ω=256°W, N Alcyonius quite evident. The Elysium area very bright near the evening limb.
On 19 June (135°Ls) at ω=216°W, Elysium large roundish in the afternoon.
On 25 June (138°Ls) at ω=154°W, Propontis I near the CM.
On 27 June (139°Ls) at ω=147°W, Olympus Mons was seen with a strange dark spot to the far north.
On 30 June (140°Ls) at ω=110°W, M Acidalium totally seen near the evening limb. Solis L was well seen as well as M Sirenum on the morning side. A cloud belt at Tractus Albus.
On 3 July (142°Ls) at ω=096°W, the main part of M Acidalium was misted.
On 4 July (142°Ls) at ω=064°W, Chryse and Tempe were misty.
On 8 July (144°Ls) at ω=038°W, M Acidalium was misty in the morning in blue. (As reported, on 27 June the HST found a dust cloud near Eos: CHr recorded that on 4 July Chryse-Xanthe was bright while on 8 July CHr stated that the area was dust free.) The observations that follow were all made in red.
On 9 July (145°Ls) at ω=048°W, the npc was not depicted while the landing site of the Pathfinder was recorded to be clear.Apparent diameter(δ) was 7.1".
On 22 July (152°Ls) at ω=261°W, the morning Syrtis Mj hidden under the thick mist.
On 25 July (153°Ls) at ω=235°W where N Alcyonius visible, Elysium bright and large roundish, and Hesperia clear.
On 30 July (156°Ls) at ω=171°W and on 1 Aug (157°Ls) at ω=151°W, Propontis I looks difficult to identify.
On 13 Aug (163°Ls) at ω=040°W, the morning side of M Acidalium was misted.
On 19 Aug (166°Ls) at ω=333°W, S Sabaeus was evident and Edom light.
On 26 Aug (170°Ls) at ω=261°W where the apparent diameter δ=5.8", Syrtis Mj was seen near the morning terminator.
Y HIGA (Hg) sent us a Video Tape surrounded with a background music where a series of the 1996/97 Mars images by him are contained from 14 Dec 1996 (051°Ls) through 20 July 1997 (151°Ls) (together with excellent images of Saturn and Jupiter in 1997).
